| 3 | Tkinter provides classes which allow the display, positioning and |
| 4 | control of widgets. Toplevel widgets are Tk and Toplevel. Other |
| 5 | widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton, |
| 6 | Checkbutton, Scale, Listbox, Scrollbar, OptionMenu. Properties of the widgets are |
| 7 | specified with keyword arguments. Keyword arguments have the same |
| 8 | name as the corresponding resource under Tk. |
| 9 | |
| 10 | Widgets are positioned with one of the geometry managers Place, Pack |
| 11 | or Grid. These managers can be called with methods place, pack, grid |
| 12 | available in every Widget. |
| 13 | |
| 14 | Actions are bound to events by resources (e.g. keyword argument command) or |
| 15 | with the method bind. |
| 16 | |
| 17 | Example (Hello, World): |
| 18 | import Tkinter |
| 19 | from Tkconstants import * |
| 20 | tk = Tkinter.Tk() |
| 21 | frame = Tkinter.Frame(tk, relief=RIDGE, borderwidth=2) |
| 22 | frame.pack(fill=BOTH,expand=1) |
| 23 | label = Tkinter.Label(frame, text="Hello, World") |
| 24 | label.pack(fill=X, expand=1) |
| 25 | button = Tkinter.Button(frame,text="Exit",command=tk.destroy) |
