| 226 | colors applied to textual tags. Color mappings are stored in |
| 227 | complete listings called themes. Built-in themes in |
| 228 | idlelib/config-highlight.def are fixed as far as the dialog is |
| 229 | concerned. Any theme can be used as the base for a new custom |
| 230 | theme, stored in .idlerc/config-highlight.cfg. |
| 231 | |
| 232 | Function load_theme_cfg() initializes tk variables and theme |
| 233 | lists and calls paint_theme_sample() and set_highlight_target() |
| 234 | for the current theme. Radiobuttons builtin_theme_on and |
| 235 | custom_theme_on toggle var theme_source, which controls if the |
| 236 | current set of colors are from a builtin or custom theme. |
| 237 | DynOptionMenus builtinlist and customlist contain lists of the |
| 238 | builtin and custom themes, respectively, and the current item |
| 239 | from each list is stored in vars builtin_name and custom_name. |
| 240 | |
| 241 | Function paint_theme_sample() applies the colors from the theme |
| 242 | to the tags in text widget highlight_sample and then invokes |
| 243 | set_color_sample(). Function set_highlight_target() sets the state |
| 244 | of the radiobuttons fg_on and bg_on based on the tag and it also |
| 245 | invokes set_color_sample(). |
| 246 | |
| 247 | Function set_color_sample() sets the background color for the frame |
| 248 | holding the color selector. This provides a larger visual of the |
| 249 | color for the current tag and plane (foreground/background). |
| 250 | |
| 251 | Note: set_color_sample() is called from many places and is often |
| 252 | called more than once when a change is made. It is invoked when |
| 253 | foreground or background is selected (radiobuttons), from |
| 254 | paint_theme_sample() (theme is changed or load_cfg is called), and |
| 255 | from set_highlight_target() (target tag is changed or load_cfg called). |

| 257 | Button delete_custom invokes delete_custom() to delete |
| 258 | a custom theme from idleConf.userCfg['highlight'] and changes. |
| 259 | Button save_custom invokes save_as_new_theme() which calls |
| 260 | get_new_theme_name() and create_new() to save a custom theme |
| 261 | and its colors to idleConf.userCfg['highlight']. |
| 262 | |
| 263 | Radiobuttons fg_on and bg_on toggle var fg_bg_toggle to control |
| 264 | if the current selected color for a tag is for the foreground or |
| 265 | background. |
| 266 | |
| 267 | DynOptionMenu targetlist contains a readable description of the |
| 268 | tags applied to Python source within IDLE. Selecting one of the |
| 269 | tags from this list populates highlight_target, which has a callback |
| 270 | function set_highlight_target(). |
| 271 | |
| 272 | Text widget highlight_sample displays a block of text (which is |
| 273 | mock Python code) in which is embedded the defined tags and reflects |
| 274 | the color attributes of the current theme and changes for those tags. |
| 275 | Mouse button 1 allows for selection of a tag and updates |
| 276 | highlight_target with that tag value. |
| 277 | |
| 278 | Note: The font in highlight_sample is set through the config in |
| 279 | the fonts tab. |
| 280 | |
| 281 | In other words, a tag can be selected either from targetlist or |
| 282 | by clicking on the sample text within highlight_sample. The |
| 283 | plane (foreground/background) is selected via the radiobutton. |
| 284 | Together, these two (tag and plane) control what color is |
| 285 | shown in set_color_sample() for the current theme. Button set_color |
| 286 | invokes get_color() which displays a ColorChooser to change the |
| 287 | color for the selected tag/plane. If a new color is picked, |
| 288 | it will be saved to changes and the highlight_sample and |
| 289 | frame background will be updated. |

| 1303 | |
| 1304 | Enable users to provisionally change foreground and background |
| 1305 | colors applied to textual tags. Color mappings are stored in |
| 1306 | complete listings called themes. Built-in themes in |
| 1307 | idlelib/config-highlight.def are fixed as far as the dialog is |
| 1308 | concerned. Any theme can be used as the base for a new custom |
| 1309 | theme, stored in .idlerc/config-highlight.cfg. |
| 1310 | |
| 1311 | Function load_theme_cfg() initializes tk variables and theme |
| 1312 | lists and calls paint_theme_sample() and set_highlight_target() |
| 1313 | for the current theme. Radiobuttons builtin_theme_on and |
| 1314 | custom_theme_on toggle var theme_source, which controls if the |
| 1315 | current set of colors are from a builtin or custom theme. |
| 1316 | DynOptionMenus builtinlist and customlist contain lists of the |
| 1317 | builtin and custom themes, respectively, and the current item |
| 1318 | from each list is stored in vars builtin_name and custom_name. |
| 1319 | |
| 1320 | Function paint_theme_sample() applies the colors from the theme |
| 1321 | to the tags in text widget highlight_sample and then invokes |
| 1322 | set_color_sample(). Function set_highlight_target() sets the state |
| 1323 | of the radiobuttons fg_on and bg_on based on the tag and it also |
| 1324 | invokes set_color_sample(). |
| 1325 | |
| 1326 | Function set_color_sample() sets the background color for the frame |
| 1327 | holding the color selector. This provides a larger visual of the |
| 1328 | color for the current tag and plane (foreground/background). |
| 1329 | |
| 1330 | Note: set_color_sample() is called from many places and is often |
| 1331 | called more than once when a change is made. It is invoked when |
| 1332 | foreground or background is selected (radiobuttons), from |
| 1333 | paint_theme_sample() (theme is changed or load_cfg is called), and |
| 1334 | from set_highlight_target() (target tag is changed or load_cfg called). |
| 1335 | |
| 1336 | Button delete_custom invokes delete_custom() to delete |
| 1337 | a custom theme from idleConf.userCfg['highlight'] and changes. |
| 1338 | Button save_custom invokes save_as_new_theme() which calls |
| 1339 | get_new_theme_name() and create_new() to save a custom theme |
| 1340 | and its colors to idleConf.userCfg['highlight']. |
| 1341 | |
| 1342 | Radiobuttons fg_on and bg_on toggle var fg_bg_toggle to control |
| 1343 | if the current selected color for a tag is for the foreground or |
| 1344 | background. |
| 1345 | |
| 1346 | DynOptionMenu targetlist contains a readable description of the |
| 1347 | tags applied to Python source within IDLE. Selecting one of the |
| 1348 | tags from this list populates highlight_target, which has a callback |
| 1349 | function set_highlight_target(). |
| 1350 | |
| 1351 | Text widget highlight_sample displays a block of text (which is |
| 1352 | mock Python code) in which is embedded the defined tags and reflects |
| 1353 | the color attributes of the current theme and changes for those tags. |
| 1354 | Mouse button 1 allows for selection of a tag and updates |
| 1355 | highlight_target with that tag value. |
| 1356 | |
| 1357 | Note: The font in highlight_sample is set through the config in |
| 1358 | the fonts tab. |
| 1359 | |
| 1360 | In other words, a tag can be selected either from targetlist or |
| 1361 | by clicking on the sample text within highlight_sample. The |
| 1362 | plane (foreground/background) is selected via the radiobutton. |
| 1363 | Together, these two (tag and plane) control what color is |
| 1364 | shown in set_color_sample() for the current theme. Button set_color |
| 1365 | invokes get_color() which displays a ColorChooser to change the |
| 1366 | color for the selected tag/plane. If a new color is picked, |
| 1367 | it will be saved to changes and the highlight_sample and |
| 1368 | frame background will be updated. |

| 1946 | |
| 1947 | Enable users to provisionally change both individual and sets of |
| 1948 | keybindings (shortcut keys). Except for features implemented as |
| 1949 | extensions, keybindings are stored in complete sets called |
| 1950 | keysets. Built-in keysets in idlelib/config-keys.def are fixed |
| 1951 | as far as the dialog is concerned. Any keyset can be used as the |
| 1952 | base for a new custom keyset, stored in .idlerc/config-keys.cfg. |
| 1953 | |
| 1954 | Function load_key_cfg() initializes tk variables and keyset |
| 1955 | lists and calls load_keys_list for the current keyset. |
| 1956 | Radiobuttons builtin_keyset_on and custom_keyset_on toggle var |
| 1957 | keyset_source, which controls if the current set of keybindings |
| 1958 | are from a builtin or custom keyset. DynOptionMenus builtinlist |
| 1959 | and customlist contain lists of the builtin and custom keysets, |
| 1960 | respectively, and the current item from each list is stored in |
| 1961 | vars builtin_name and custom_name. |
| 1962 | |
| 1963 | Button delete_custom_keys invokes delete_custom_keys() to delete |
| 1964 | a custom keyset from idleConf.userCfg['keys'] and changes. Button |
| 1965 | save_custom_keys invokes save_as_new_key_set() which calls |
| 1966 | get_new_keys_name() and create_new_key_set() to save a custom keyset |
| 1967 | and its keybindings to idleConf.userCfg['keys']. |
| 1968 | |
| 1969 | Listbox bindingslist contains all of the keybindings for the |
| 1970 | selected keyset. The keybindings are loaded in load_keys_list() |
| 1971 | and are pairs of (event, [keys]) where keys can be a list |
| 1972 | of one or more key combinations to bind to the same event. |
| 1973 | Mouse button 1 click invokes on_bindingslist_select(), which |
| 1974 | allows button_new_keys to be clicked. |
| 1975 | |
| 1976 | So, an item is selected in listbindings, which activates |
| 1977 | button_new_keys, and clicking button_new_keys calls function |
| 1978 | get_new_keys(). Function get_new_keys() gets the key mappings from the |
| 1979 | current keyset for the binding event item that was selected. The |
| 1980 | function then displays another dialog, GetKeysDialog, with the |
Cheryl Sabella | 82aff62 | 2017-08-17 20:39:00 -0400 | [diff] [blame] | 1981 | selected binding event and current keys and allows new key sequences |
Cheryl Sabella | e36d9f5 | 2017-08-15 18:26:23 -0400 | [diff] [blame] | 1982 | to be entered for that binding event. If the keys aren't |
| 1983 | changed, nothing happens. If the keys are changed and the keyset |
| 1984 | is a builtin, function get_new_keys_name() will be called |
| 1985 | for input of a custom keyset name. If no name is given, then the |
| 1986 | change to the keybinding will abort and no updates will be made. If |
| 1987 | a custom name is entered in the prompt or if the current keyset was |
| 1988 | already custom (and thus didn't require a prompt), then |
| 1989 | idleConf.userCfg['keys'] is updated in function create_new_key_set() |
| 1990 | with the change to the event binding. The item listing in bindingslist |
| 1991 | is updated with the new keys. Var keybinding is also set which invokes |
| 1992 | the callback function, var_changed_keybinding, to add the change to |
| 1993 | the 'keys' or 'extensions' changes tracker based on the binding type. |
