| 11 | The :mod:`tkinter.ttk` module provides access to the Tk themed widget set, |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 12 | introduced in Tk 8.5. If Python has not been compiled against Tk 8.5, this |
| 13 | module can still be accessed if *Tile* has been installed. The former |
| 14 | method using Tk 8.5 provides additional benefits including anti-aliased font |
| 15 | rendering under X11 and window transparency (requiring a composition |
| 16 | window manager on X11). |

Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 18 | The basic idea for :mod:`tkinter.ttk` is to separate, to the extent possible, |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 19 | the code implementing a widget's behavior from the code implementing its |
| 20 | appearance. |

| 29 | Using Ttk |
| 30 | --------- |
| 31 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 32 | To start using Ttk, import its module:: |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 33 | |
| 34 | from tkinter import ttk |
| 35 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 36 | To override the basic Tk widgets, the import should follow the Tk import:: |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 37 | |
| 38 | from tkinter import * |
| 39 | from tkinter.ttk import * |
| 40 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 41 | That code causes several :mod:`tkinter.ttk` widgets (:class:`Button`, |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 42 | :class:`Checkbutton`, :class:`Entry`, :class:`Frame`, :class:`Label`, |
| 43 | :class:`LabelFrame`, :class:`Menubutton`, :class:`PanedWindow`, |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 44 | :class:`Radiobutton`, :class:`Scale` and :class:`Scrollbar`) to |
| 45 | automatically replace the Tk widgets. |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 46 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 47 | This has the direct benefit of using the new widgets which gives a better |
| 48 | look and feel across platforms; however, the replacement widgets are not |
| 49 | completely compatible. The main difference is that widget options such as |
| 50 | "fg", "bg" and others related to widget styling are no |
| 51 | longer present in Ttk widgets. Instead, use the :class:`ttk.Style` class |
| 52 | for improved styling effects. |

| 62 | Ttk Widgets |
| 63 | ----------- |
| 64 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 65 | Ttk comes with 17 widgets, eleven of which already existed in tkinter: |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 66 | :class:`Button`, :class:`Checkbutton`, :class:`Entry`, :class:`Frame`, |
| 67 | :class:`Label`, :class:`LabelFrame`, :class:`Menubutton`, :class:`PanedWindow`, |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 68 | :class:`Radiobutton`, :class:`Scale` and :class:`Scrollbar`. The other six are |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 69 | new: :class:`Combobox`, :class:`Notebook`, :class:`Progressbar`, |
| 70 | :class:`Separator`, :class:`Sizegrip` and :class:`Treeview`. And all them are |
| 71 | subclasses of :class:`Widget`. |
| 72 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 73 | Using the Ttk widgets gives the application an improved look and feel. |
| 74 | As discussed above, there are differences in how the styling is coded. |

| 93 | Widget |
| 94 | ------ |
| 95 | |
| 96 | :class:`ttk.Widget` defines standard options and methods supported by Tk |
| 97 | themed widgets and is not supposed to be directly instantiated. |
| 98 | |
| 99 | |
| 100 | Standard Options |
| 101 | ^^^^^^^^^^^^^^^^ |
| 102 | |
| 103 | All the :mod:`ttk` Widgets accepts the following options: |
| 104 | |
| 105 | +-----------+--------------------------------------------------------------+ |
| 106 | | Option | Description | |
| 107 | +===========+==============================================================+ |
| 108 | | class | Specifies the window class. The class is used when querying | |
| 109 | | | the option database for the window's other options, to | |
| 110 | | | determine the default bindtags for the window, and to select | |
| 111 | | | the widget's default layout and style. This is a read-only | |
| 112 | | | which may only be specified when the window is created | |
| 113 | +-----------+--------------------------------------------------------------+ |
| 114 | | cursor | Specifies the mouse cursor to be used for the widget. If set | |
| 115 | | | to the empty string (the default), the cursor is inherited | |
| 116 | | | for the parent widget. | |
| 117 | +-----------+--------------------------------------------------------------+ |
| 118 | | takefocus | Determines whether the window accepts the focus during | |
| 119 | | | keyboard traversal. 0, 1 or an empty is return. If 0 is | |
| 120 | | | returned, it means that the window should be skipped entirely| |
| 121 | | | during keyboard traversal. If 1, it means that the window | |
| 122 | | | should receive the input focus as long as it is viewable. And| |
| 123 | | | an empty string means that the traversal scripts make the | |
| 124 | | | decision about whether or not to focus on the window. | |
| 125 | +-----------+--------------------------------------------------------------+ |
| 126 | | style | May be used to specify a custom widget style. | |
| 127 | +-----------+--------------------------------------------------------------+ |
| 128 | |
| 129 | |
| 130 | Scrollable Widget Options |
| 131 | ^^^^^^^^^^^^^^^^^^^^^^^^^ |
| 132 | |
| 133 | The following options are supported by widgets that are controlled by a |
| 134 | scrollbar. |
| 135 | |
| 136 | +----------------+---------------------------------------------------------+ |
| 137 | | option | description | |
| 138 | +================+=========================================================+ |
Georg Brandl | ae2dbe2 | 2009-03-13 19:04:40 +0000 | [diff] [blame] | 139 | | xscrollcommand | Used to communicate with horizontal scrollbars. | |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 140 | | | | |
| 141 | | | When the view in the widget's window change, the widget | |
| 142 | | | will generate a Tcl command based on the scrollcommand. | |
| 143 | | | | |
| 144 | | | Usually this option consists of the method | |
| 145 | | | :meth:`Scrollbar.set` of some scrollbar. This will cause| |
| 146 | | | the scrollbar to be updated whenever the view in the | |
| 147 | | | window changes. | |
| 148 | +----------------+---------------------------------------------------------+ |
Georg Brandl | ae2dbe2 | 2009-03-13 19:04:40 +0000 | [diff] [blame] | 149 | | yscrollcommand | Used to communicate with vertical scrollbars. | |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 150 | | | For some more information, see above. | |
| 151 | +----------------+---------------------------------------------------------+ |
| 152 | |
| 153 | |
| 154 | Label Options |
| 155 | ^^^^^^^^^^^^^ |
| 156 | |
| 157 | The following options are supported by labels, buttons and other button-like |
| 158 | widgets. |
| 159 | |
| 160 | +--------------+-----------------------------------------------------------+ |
| 161 | | option | description | |
| 162 | +==============+===========================================================+ |
| 163 | | text | Specifies a text string to be displayed inside the widget.| |
| 164 | +--------------+-----------------------------------------------------------+ |
| 165 | | textvariable | Specifies a name whose value will be used in place of the | |
| 166 | | | text option resource. | |
| 167 | +--------------+-----------------------------------------------------------+ |
| 168 | | underline | If set, specifies the index (0-based) of a character to | |
| 169 | | | underline in the text string. The underline character is | |
| 170 | | | used for mnemonic activation. | |
| 171 | +--------------+-----------------------------------------------------------+ |
| 172 | | image | Specifies an image to display. This is a list of 1 or more| |
| 173 | | | elements. The first element is the default image name. The| |
| 174 | | | rest of the list if a sequence of statespec/value pairs as| |
| 175 | | | defined by :meth:`Style.map`, specifying different images | |
| 176 | | | to use when the widget is in a particular state or a | |
| 177 | | | combination of states. All images in the list should have | |
| 178 | | | the same size. | |
| 179 | +--------------+-----------------------------------------------------------+ |
| 180 | | compound | Specifies how to display the image relative to the text, | |
| 181 | | | in the case both text and images options are present. | |
| 182 | | | Valid values are: | |
| 183 | | | | |
| 184 | | | * text: display text only | |
| 185 | | | * image: display image only | |
| 186 | | | * top, bottom, left, right: display image above, below, | |
| 187 | | | left of, or right of the text, respectively. | |
| 188 | | | * none: the default. display the image if present, | |
| 189 | | | otherwise the text. | |
| 190 | +--------------+-----------------------------------------------------------+ |
| 191 | | width | If greater than zero, specifies how much space, in | |
| 192 | | | character widths, to allocate for the text label, if less | |
| 193 | | | than zero, specifies a minimum width. If zero or | |
| 194 | | | unspecified, the natural width of the text label is used. | |
| 195 | +--------------+-----------------------------------------------------------+ |
| 196 | |
| 197 | |
| 198 | Compatibility Options |
| 199 | ^^^^^^^^^^^^^^^^^^^^^ |
| 200 | |
| 201 | +--------+----------------------------------------------------------------+ |
| 202 | | option | description | |
| 203 | +========+================================================================+ |
| 204 | | state | May be set to "normal" or "disabled" to control the "disabled" | |
| 205 | | | state bit. This is a write-only option: setting it changes the | |
| 206 | | | widget state, but the :meth:`Widget.state` method does not | |
| 207 | | | affect this option. | |
| 208 | +--------+----------------------------------------------------------------+ |
| 209 | |
| 210 | Widget States |
| 211 | ^^^^^^^^^^^^^ |
| 212 | |
| 213 | The widget state is a bitmap of independent state flags. |
| 214 | |
| 215 | +------------+-------------------------------------------------------------+ |
| 216 | | flag | description | |
| 217 | +============+=============================================================+ |
| 218 | | active | The mouse cursor is over the widget and pressing a mouse | |
| 219 | | | button will cause some action to occur | |
| 220 | +------------+-------------------------------------------------------------+ |
| 221 | | disabled | Widget is disabled under program control | |
| 222 | +------------+-------------------------------------------------------------+ |
| 223 | | focus | Widget has keyboard focus | |
| 224 | +------------+-------------------------------------------------------------+ |
| 225 | | pressed | Widget is being pressed | |
| 226 | +------------+-------------------------------------------------------------+ |
| 227 | | selected | "On", "true", or "current" for things like Checkbuttons and | |
| 228 | | | radiobuttons | |
| 229 | +------------+-------------------------------------------------------------+ |
| 230 | | background | Windows and Mac have a notion of an "active" or foreground | |
| 231 | | | window. The *background* state is set for widgets in a | |
| 232 | | | background window, and cleared for those in the foreground | |
| 233 | | | window | |
| 234 | +------------+-------------------------------------------------------------+ |
| 235 | | readonly | Widget should not allow user modification | |
| 236 | +------------+-------------------------------------------------------------+ |
| 237 | | alternate | A widget-specific alternate display format | |
| 238 | +------------+-------------------------------------------------------------+ |
| 239 | | invalid | The widget's value is invalid | |
| 240 | +------------+-------------------------------------------------------------+ |
| 241 | |
| 242 | A state specification is a sequence of state names, optionally prefixed with |
| 243 | an exclamation point indicating that the bit is off. |
| 244 | |
| 245 | |
| 246 | ttk.Widget |
| 247 | ^^^^^^^^^^ |
| 248 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 249 | Besides the methods described below, the :class:`ttk.Widget` supports the |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 250 | methods :meth:`tkinter.Widget.cget` and :meth:`tkinter.Widget.configure`. |
| 251 | |
| 252 | .. class:: Widget |
| 253 | |
| 254 | .. method:: identify(x, y) |
| 255 | |
| 256 | Returns the name of the element at position *x* *y*, or the empty string |
| 257 | if the point does not lie within any element. |
| 258 | |
| 259 | *x* and *y* are pixel coordinates relative to the widget. |
| 260 | |
| 261 | |
| 262 | .. method:: instate(statespec[, callback=None[, *args[, **kw]]]) |
| 263 | |
| 264 | Test the widget's state. If a callback is not specified, returns True |
| 265 | if the widget state matches *statespec* and False otherwise. If callback |
| 266 | is specified then it is called with args if widget state matches |
| 267 | *statespec*. |
| 268 | |
| 269 | |
| 270 | .. method:: state([statespec=None]) |
| 271 | |
| 272 | Modify or inquire widget state. If *statespec* is specified, sets the |
| 273 | widget state according to it and return a new *statespec* indicating |
| 274 | which flags were changed. If *statespec* is not specified, returns |
| 275 | the currently-enabled state flags. |
| 276 | |
| 277 | *statespec* will usually be a list or a tuple. |
| 278 | |
| 279 | |
| 280 | Combobox |
| 281 | -------- |
| 282 | |
| 283 | The :class:`ttk.Combobox` widget combines a text field with a pop-down list of |
| 284 | values. This widget is a subclass of :class:`Entry`. |
| 285 | |
| 286 | Besides the methods inherited from :class:`Widget`: :meth:`Widget.cget`, |
| 287 | :meth:`Widget.configure`, :meth:`Widget.identify`, :meth:`Widget.instate` |
| 288 | and :meth:`Widget.state`, and the following inherited from :class:`Entry`: |
| 289 | :meth:`Entry.bbox`, :meth:`Entry.delete`, :meth:`Entry.icursor`, |
| 290 | :meth:`Entry.index`, :meth:`Entry.inset`, :meth:`Entry.selection`, |
| 291 | :meth:`Entry.xview`, it has some other methods, described at |
| 292 | :class:`ttk.Combobox`. |
| 293 | |
| 294 | |
| 295 | Options |
| 296 | ^^^^^^^ |
| 297 | |
| 298 | This widget accepts the following specific options: |
| 299 | |
| 300 | +-----------------+--------------------------------------------------------+ |
| 301 | | option | description | |
| 302 | +=================+========================================================+ |
| 303 | | exportselection | Boolean value. If set, the widget selection is linked | |
| 304 | | | to the Window Manager selection (which can be returned | |
| 305 | | | by invoking Misc.selection_get, for example). | |
| 306 | +-----------------+--------------------------------------------------------+ |
| 307 | | justify | Specifies how the text is aligned within the widget. | |
| 308 | | | One of "left", "center", or "right". | |
| 309 | +-----------------+--------------------------------------------------------+ |
| 310 | | height | Specifies the height of the pop-down listbox, in rows. | |
| 311 | +-----------------+--------------------------------------------------------+ |
| 312 | | postcommand | A script (possibly registered with Misc.register) that | |
| 313 | | | is called immediately before displaying the values. It | |
| 314 | | | may specify which values to display. | |
| 315 | +-----------------+--------------------------------------------------------+ |
| 316 | | state | One of "normal", "readonly", or "disabled". In the | |
| 317 | | | "readonly" state, the value may not be edited directly,| |
| 318 | | | and the user can only selection of the values from the | |
| 319 | | | dropdown list. In the "normal" state, the text field is| |
| 320 | | | directly editable. In the "disabled" state, no | |
| 321 | | | interaction is possible. | |
| 322 | +-----------------+--------------------------------------------------------+ |
| 323 | | textvariable | Specifies a name whose value is linked to the widget | |
| 324 | | | value. Whenever the value associated with that name | |
| 325 | | | changes, the widget value is updated, and vice versa. | |
| 326 | | | See :class:`tkinter.StringVar`. | |
| 327 | +-----------------+--------------------------------------------------------+ |
| 328 | | values | Specifies the list of values to display in the | |
| 329 | | | drop-down listbox. | |
| 330 | +-----------------+--------------------------------------------------------+ |
| 331 | | width | Specifies an integer value indicating the desired width| |
| 332 | | | of the entry window, in average-size characters of the | |
| 333 | | | widget's font. | |
| 334 | +-----------------+--------------------------------------------------------+ |
| 335 | |
| 336 | |
| 337 | Virtual events |
| 338 | ^^^^^^^^^^^^^^ |
| 339 | |
| 340 | The combobox widgets generates a **<<ComboboxSelected>>** virtual event |
| 341 | when the user selects an element from the list of values. |
| 342 | |
| 343 | |
| 344 | ttk.Combobox |
| 345 | ^^^^^^^^^^^^ |
| 346 | |
| 347 | .. class:: Combobox |
| 348 | |
| 349 | .. method:: current([newindex=None]) |
| 350 | |
| 351 | If *newindex* is specified, sets the combobox value to the element |
| 352 | position *newindex*. Otherwise, returns the index of the current value or |
| 353 | -1 if the current value is not in the values list. |
| 354 | |
| 355 | |
| 356 | .. method:: get() |
| 357 | |
| 358 | Returns the current value of the combobox. |
| 359 | |
| 360 | |
| 361 | .. method:: set(value) |
| 362 | |
| 363 | Sets the value of the combobox to *value*. |
| 364 | |
| 365 | |
| 366 | Notebook |
| 367 | -------- |
| 368 | |
| 369 | Ttk Notebook widget manages a collection of windows and displays a single |
| 370 | one at a time. Each child window is associated with a tab, which the user |
| 371 | may select to change the currently-displayed window. |
| 372 | |
| 373 | |
| 374 | Options |
| 375 | ^^^^^^^ |
| 376 | |
| 377 | This widget accepts the following specific options: |
| 378 | |
| 379 | +---------+----------------------------------------------------------------+ |
| 380 | | option | description | |
| 381 | +=========+================================================================+ |
| 382 | | height | If present and greater than zero, specifies the desired height | |
| 383 | | | of the pane area (not including internal padding or tabs). | |
| 384 | | | Otherwise, the maximum height of all panes is used. | |
| 385 | +---------+----------------------------------------------------------------+ |
| 386 | | padding | Specifies the amount of extra space to add around the outside | |
| 387 | | | of the notebook. The padding is a list up to four length | |
| 388 | | | specifications left top right bottom. If fewer than four | |
| 389 | | | elements are specified, bottom defaults to top, right defaults | |
| 390 | | | to left, and top defaults to left. | |
| 391 | +---------+----------------------------------------------------------------+ |
| 392 | | width | If present and greater than zero, specified the desired width | |
| 393 | | | of the pane area (not including internal padding). Otherwise, | |
| 394 | | | the maximum width of all panes is used. | |
| 395 | +---------+----------------------------------------------------------------+ |
| 396 | |
| 397 | |
| 398 | Tab Options |
| 399 | ^^^^^^^^^^^ |
| 400 | |
| 401 | There are also specific options for tabs: |
| 402 | |
| 403 | +-----------+--------------------------------------------------------------+ |
| 404 | | option | description | |
| 405 | +===========+==============================================================+ |
| 406 | | state | Either "normal", "disabled" or "hidden". If "disabled", then | |
| 407 | | | the tab is not selectable. If "hidden", then the tab is not | |
| 408 | | | shown. | |
| 409 | +-----------+--------------------------------------------------------------+ |
| 410 | | sticky | Specifies how the child window is positioned within the pane | |
| 411 | | | area. Value is a string containing zero or more of the | |
| 412 | | | characters "n", "s", "e" or "w". Each letter refers to a | |
| 413 | | | side (north, south, east or west) that the child window will | |
| 414 | | | stick to, as per the :meth:`grid` geometry manager. | |
| 415 | +-----------+--------------------------------------------------------------+ |
| 416 | | padding | Specifies the amount of extra space to add between the | |
| 417 | | | notebook and this pane. Syntax is the same as for the option | |
| 418 | | | padding used by this widget. | |
| 419 | +-----------+--------------------------------------------------------------+ |
| 420 | | text | Specifies a text to be displayed in the tab. | |
| 421 | +-----------+--------------------------------------------------------------+ |
| 422 | | image | Specifies an image to display in the tab. See the option | |
| 423 | | | image described in :class:`Widget`. | |
| 424 | +-----------+--------------------------------------------------------------+ |
| 425 | | compound | Specifies how to display the image relative to the text, in | |
| 426 | | | the case both options text and image are present. See | |
| 427 | | | `Label Options`_ for legal values. | |
| 428 | +-----------+--------------------------------------------------------------+ |
| 429 | | underline | Specifies the index (0-based) of a character to underline in | |
| 430 | | | the text string. The underlined character is used for | |
| 431 | | | mnemonic activation if :meth:`Notebook.enable_traversal` is | |
| 432 | | | called. | |
| 433 | +-----------+--------------------------------------------------------------+ |
| 434 | |
| 435 | |
| 436 | Tab Identifiers |
| 437 | ^^^^^^^^^^^^^^^ |
| 438 | |
| 439 | The tab_id present in several methods of :class:`ttk.Notebook` may take any |
| 440 | of the following forms: |
| 441 | |
| 442 | * An integer between zero and the number of tabs |
| 443 | * The name of a child window |
| 444 | * A positional specification of the form "@x,y", which identifies the tab |
| 445 | * The literal string "current", which identifies the currently-selected tab |
| 446 | * The literal string "end", which returns the number of tabs (only valid for |
| 447 | :meth:`Notebook.index`) |
| 448 | |
| 449 | |
| 450 | Virtual Events |
| 451 | ^^^^^^^^^^^^^^ |
| 452 | |
| 453 | This widget generates a **<<NotebookTabChanged>>** virtual event after a new |
| 454 | tab is selected. |
| 455 | |
| 456 | |
| 457 | ttk.Notebook |
| 458 | ^^^^^^^^^^^^ |
| 459 | |
| 460 | .. class:: Notebook |
| 461 | |
| 462 | .. method:: add(child, **kw) |
| 463 | |
| 464 | Adds a new tab to the notebook. |
| 465 | |
| 466 | If window is currently managed by the notebook but hidden, it is |
| 467 | restored to its previous position. |
| 468 | |
| 469 | See `Tab Options`_ for the list of available options. |
| 470 | |
| 471 | |

| 496 | number of tabs if *tab_id* is the string "end". |
| 497 | |
| 498 | |
| 499 | .. method:: insert(pos, child, **kw) |
| 500 | |
| 501 | Inserts a pane at the specified position. |
| 502 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 503 | *pos* is either the string "end", an integer index, or the name of a |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 504 | managed child. If *child* is already managed by the notebook, moves it to |
| 505 | the specified position. |
| 506 | |
| 507 | See `Tab Options`_ for the list of available options. |
| 508 | |
| 509 | |
| 510 | .. method:: select([tab_id]) |
| 511 | |
| 512 | Selects the specified *tab_id*. |
| 513 | |
| 514 | The associated child window will be displayed, and the |

Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 524 | *option* is specified, returns the value of that *option*. Otherwise, |
| 525 | sets the options to the corresponding values. |
| 526 | |
| 527 | |
| 528 | .. method:: tabs() |
| 529 | |
| 530 | Returns a list of windows managed by the notebook. |
| 531 | |
| 532 | |
| 533 | .. method:: enable_traversal() |
| 534 | |
| 535 | Enable keyboard traversal for a toplevel window containing this notebook. |
| 536 | |
| 537 | This will extend the bindings for the toplevel window containing the |
| 538 | notebook as follows: |

Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 542 | * Alt-K: where K is the mnemonic (underlined) character of any tab, will |
| 543 | select that tab. |
| 544 | |
| 545 | Multiple notebooks in a single toplevel may be enabled for traversal, |
| 546 | including nested notebooks. However, notebook traversal only works |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 547 | properly if all panes have the notebook they are in as master. |

| 550 | Progressbar |
| 551 | ----------- |
| 552 | |
| 553 | The :class:`ttk.Progressbar` widget shows the status of a long-running |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 554 | operation. It can operate in two modes: 1) the determinate mode which shows the |
| 555 | amount completed relative to the total amount of work to be done and 2) the |
| 556 | indeterminate mode which provides an animated display to let the user know that |
| 557 | work is progressing. |

| 560 | Options |
| 561 | ^^^^^^^ |
| 562 | |
| 563 | This widget accepts the following specific options: |
| 564 | |
| 565 | +----------+---------------------------------------------------------------+ |
| 566 | | option | description | |
| 567 | +==========+===============================================================+ |
| 568 | | orient | One of "horizontal" or "vertical". Specifies the orientation | |
| 569 | | | of the progress bar. | |
| 570 | +----------+---------------------------------------------------------------+ |
| 571 | | length | Specifies the length of the long axis of the progress bar | |
| 572 | | | (width if horizontal, height if vertical). | |
| 573 | +----------+---------------------------------------------------------------+ |
| 574 | | mode | One of "determinate" or "indeterminate". | |
| 575 | +----------+---------------------------------------------------------------+ |
| 576 | | maximum | A number specifying the maximum value. Defaults to 100. | |
| 577 | +----------+---------------------------------------------------------------+ |
| 578 | | value | The current value of the progress bar. In "determinate" mode, | |
| 579 | | | this represents the amount of work completed. In | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 580 | | | "indeterminate" mode, it is interpreted as modulo *maximum*; | |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 581 | | | that is, the progress bar completes one "cycle" when its value| |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 582 | | | increases by *maximum*. | |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 583 | +----------+---------------------------------------------------------------+ |
| 584 | | variable | A name which is linked to the option value. If specified, the | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 585 | | | value of the progress bar is automatically set to the value of| |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 586 | | | this name whenever the latter is modified. | |
| 587 | +----------+---------------------------------------------------------------+ |
| 588 | | phase | Read-only option. The widget periodically increments the value| |
| 589 | | | of this option whenever its value is greater than 0 and, in | |
| 590 | | | determinate mode, less than maximum. This option may be used | |
| 591 | | | by the current theme to provide additional animation effects. | |
| 592 | +----------+---------------------------------------------------------------+ |
| 593 | |

| 644 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 645 | The :class:`ttk.Sizegrip` widget (also known as a grow box) allows the user to |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 646 | resize the containing toplevel window by pressing and dragging the grip. |
| 647 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 648 | This widget has neither specific options nor specific methods, besides the |

| 650 | |
| 651 | |
| 652 | Platform-specific notes |
| 653 | ^^^^^^^^^^^^^^^^^^^^^^^ |
| 654 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 655 | * On MacOS X, toplevel windows automatically include a built-in size grip |
| 656 | by default. Adding a :class:`Sizegrip` is harmless, since the built-in |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 657 | grip will just mask the widget. |
| 658 | |
| 659 | |
| 660 | Bugs |
| 661 | ^^^^ |
| 662 | |
| 663 | * If the containing toplevel's position was specified relative to the right |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 664 | or bottom of the screen (e.g. ....), the :class:`Sizegrip` widget will |
| 665 | not resize the window. |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 666 | * This widget supports only "southeast" resizing. |
| 667 | |
| 668 | |
| 669 | Treeview |
| 670 | -------- |
| 671 | |
| 672 | The :class:`ttk.Treeview` widget displays a hierarchical collection of items. |
| 673 | Each item has a textual label, an optional image, and an optional list of data |
| 674 | values. The data values are displayed in successive columns after the tree |
| 675 | label. |
| 676 | |
| 677 | The order in which data values are displayed may be controlled by setting |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 678 | the widget option ``displaycolumns``. The tree widget can also display column |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 679 | headings. Columns may be accessed by number or symbolic names listed in the |
| 680 | widget option columns. See `Column Identifiers`_. |
| 681 | |
| 682 | Each item is identified by an unique name. The widget will generate item IDs |
| 683 | if they are not supplied by the caller. There is a distinguished root item, |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 684 | named ``{}``. The root item itself is not displayed; its children appear at the |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 685 | top level of the hierarchy. |
| 686 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 687 | Each item also has a list of tags, which can be used to associate event bindings |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 688 | with individual items and control the appearance of the item. |
| 689 | |
| 690 | The Treeview widget supports horizontal and vertical scrolling, according to |
| 691 | the options described in `Scrollable Widget Options`_ and the methods |
| 692 | :meth:`Treeview.xview` and :meth:`Treeview.yview`. |

| 761 | | | than columns, the extra values are ignored. | |
| 762 | +--------+---------------------------------------------------------------+ |
| 763 | | open | True/False value indicating whether the item's children should| |
| 764 | | | be displayed or hidden. | |
| 765 | +--------+---------------------------------------------------------------+ |
| 766 | | tags | A list of tags associated with this item. | |
| 767 | +--------+---------------------------------------------------------------+ |
| 768 | |
| 769 | |
| 770 | Tag Options |
| 771 | ^^^^^^^^^^^ |
| 772 | |
| 773 | The following options may be specified on tags: |
| 774 | |
| 775 | +------------+-----------------------------------------------------------+ |
| 776 | | option | description | |
| 777 | +============+===========================================================+ |
| 778 | | foreground | Specifies the text foreground color. | |
| 779 | +------------+-----------------------------------------------------------+ |
| 780 | | background | Specifies the cell or item background color. | |
| 781 | +------------+-----------------------------------------------------------+ |
| 782 | | font | Specifies the font to use when drawing text. | |
| 783 | +------------+-----------------------------------------------------------+ |
| 784 | | image | Specifies the item image, in case the item's image option | |
| 785 | | | is empty. | |
| 786 | +------------+-----------------------------------------------------------+ |
| 787 | |
| 788 | |
| 789 | Column Identifiers |
| 790 | ^^^^^^^^^^^^^^^^^^ |
| 791 | |
| 792 | Column identifiers take any of the following forms: |
| 793 | |
| 794 | * A symbolic name from the list of columns option. |
| 795 | * An integer n, specifying the nth data column. |
| 796 | * A string of the form #n, where n is an integer, specifying the nth display |
| 797 | column. |
| 798 | |
| 799 | Notes: |
| 800 | |
| 801 | * Item's option values may be displayed in a different order than the order |
| 802 | in which they are stored. |
| 803 | * Column #0 always refers to the tree column, even if show="tree" is not |
| 804 | specified. |
| 805 | |
| 806 | A data column number is an index into an item's option values list; a display |
| 807 | column number is the column number in the tree where the values are displayed. |
| 808 | Tree labels are displayed in column #0. If option displaycolumns is not set, |
| 809 | then data column n is displayed in column #n+1. Again, **column #0 always |
| 810 | refers to the tree column**. |
| 811 | |
| 812 | |
| 813 | Virtual Events |
| 814 | ^^^^^^^^^^^^^^ |
| 815 | |
| 816 | The Treeview widget generates the following virtual events. |
| 817 | |
| 818 | +--------------------+--------------------------------------------------+ |
| 819 | | event | description | |
| 820 | +====================+==================================================+ |
| 821 | | <<TreeviewSelect>> | Generated whenever the selection changes. | |
| 822 | +--------------------+--------------------------------------------------+ |
| 823 | | <<TreeviewOpen>> | Generated just before settings the focus item to | |
| 824 | | | open=True. | |
| 825 | +--------------------+--------------------------------------------------+ |
| 826 | | <<TreeviewClose>> | Generated just after setting the focus item to | |
| 827 | | | open=False. | |
| 828 | +--------------------+--------------------------------------------------+ |
| 829 | |
| 830 | The :meth:`Treeview.focus` and :meth:`Treeview.selection` methods can be used |
| 831 | to determine the affected item or items. |

| 1139 | elements making up the widget and how they are arranged, along with dynamic |
| 1140 | and default settings for element options. By default the style name is the |
| 1141 | same as the widget's class name, but it may be overriden by the widget's style |
| 1142 | option. If you don't know the class name of a widget, use the method |

Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1184 | Each key in *kw* is an option and each value should be a list or a |
| 1185 | tuple (usually) containing statespecs grouped in tuples, lists, or |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 1186 | some other preference. A statespec is a compound of one |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1187 | or more states and then a value. |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 1188 | |
| 1189 | An example may make it more understandable:: |
| 1190 | |
| 1191 | import tkinter |
| 1192 | from tkinter import ttk |
| 1193 | |
| 1194 | root = tkinter.Tk() |

| 1197 | style.map("C.TButton", |
| 1198 | foreground=[('pressed', 'red'), ('active', 'blue')], |
| 1199 | background=[('pressed', '!disabled', 'black'), ('active', 'white')] |
| 1200 | ) |
| 1201 | |
| 1202 | colored_btn = ttk.Button(text="Test", style="C.TButton").pack() |
| 1203 | |
| 1204 | root.mainloop() |
| 1205 | |
| 1206 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1207 | Note that the order of the (states, value) sequences for an option does |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 1208 | matter, if the order is changed to ``[('active', 'blue'), ('pressed', |
| 1209 | 'red')]`` in the foreground option, for example, the result would be a |
| 1210 | blue foreground when the widget were in active or pressed states. |

| 1212 | |
| 1213 | .. method:: lookup(style, option[, state=None[, default=None]]) |
| 1214 | |
| 1215 | Returns the value specified for *option* in *style*. |
| 1216 | |
| 1217 | If *state* is specified, it is expected to be a sequence of one or more |
| 1218 | states. If the *default* argument is set, it is used as a fallback value |
| 1219 | in case no specification for option is found. |
| 1220 | |
Raymond Hettinger | 238018c | 2009-04-08 08:23:44 +0000 | [diff] [blame] | 1221 | To check what font a Button uses by default:: |

| 1226 | |
| 1227 | |
| 1228 | .. method:: layout(style[, layoutspec=None]) |
| 1229 | |
| 1230 | Define the widget layout for given *style*. If *layoutspec* is omitted, |
| 1231 | return the layout specification for given style. |
| 1232 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1233 | *layoutspec*, if specified, is expected to be a list or some other |
| 1234 | sequence type (excluding strings), where each item should be a tuple and |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 1235 | the first item is the layout name and the second item should have the |

| 1267 | available in Tk 8.6a for Windows XP and Vista and is not described here. |
| 1268 | |
| 1269 | If "image" is used, *args* should contain the default image name followed |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1270 | by statespec/value pairs (this is the imagespec), and *kw* may have the |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 1271 | following options: |
| 1272 | |
| 1273 | * border=padding |
| 1274 | padding is a list of up to four integers, specifying the left, top, |
| 1275 | right, and bottom borders, respectively. |
| 1276 | |
| 1277 | * height=height |

| 1280 | |
| 1281 | * padding=padding |
| 1282 | Specifies the element's interior padding. Defaults to border's value |
| 1283 | if not specified. |
| 1284 | |
| 1285 | * sticky=spec |
| 1286 | Specifies how the image is placed within the final parcel. spec |
| 1287 | contains zero or more characters “n”, “s”, “w”, or “e”. |
| 1288 | |
| 1289 | * width=width |
| 1290 | Specifies a minimum width for the element. If less than zero, the |

| 1292 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1293 | If "from" is used as the value of *etype*, |

| 1372 | |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1373 | A layout can be just None, if it takes no options, or a dict of |
| 1374 | options specifying how to arrange the element. The layout mechanism |
| 1375 | uses a simplified version of the pack geometry manager: given an |
| 1376 | initial cavity, each element is allocated a parcel. Valid |
| 1377 | options/values are: |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 1378 | |
| 1379 | * side: whichside |
Benjamin Peterson | d23f822 | 2009-04-05 19:13:16 +0000 | [diff] [blame] | 1380 | Specifies which side of the cavity to place the element; one of |
Guilherme Polo | 5f23848 | 2009-01-28 14:41:10 +0000 | [diff] [blame] | 1381 | top, right, bottom or left. If omitted, the element occupies the |
| 1382 | entire cavity. |
| 1383 | |
| 1384 | * sticky: nswe |
| 1385 | Specifies where the element is placed inside its allocated parcel. |
| 1386 | |
| 1387 | * unit: 0 or 1 |
| 1388 | If set to 1, causes the element and all of its descendants to be treated as |
| 1389 | a single element for the purposes of :meth:`Widget.identify` et al. It's |
| 1390 | used for things like scrollbar thumbs with grips. |
| 1391 | |
| 1392 | * children: [sublayout... ] |
| 1393 | Specifies a list of elements to place inside the element. Each |
| 1394 | element is a tuple (or other sequence type) where the first item is |
| 1395 | the layout name, and the other is a `Layout`_. |
| 1396 | |
