Tkinter supports 15 core widgets:
Table 4-1. Tkinter Widget Classes
| Widget | Description |
|---|---|
| Button | A simple button, used to execute a command or other operation. |
| Canvas | Structured graphics. This widget can be used to draw graphs and plots, create graphics editors, and to implement custom widgets. |
| Checkbutton | Represents a variable that can have two distinct values. Clicking the button toggles between the values. |
| Entry | A text entry field. |
| Frame | A container widget. The frame can have a border and a background, and is used to group other widgets when creating an application or dialog layout. |
| Label | Displays a text or an image. |
| Listbox | Displays a list of alternatives. The listbox can be configured to get radiobutton or checklist behavior. |
| Menu | A menu pane. Used to implement pulldown and popup menus. |
| Menubutton | A menubutton. Used to implement pulldown menus. |
| Message | Display a text. Similar to the label widget, but can automatically wrap text to a given width or aspect ratio. |
| Radiobutton | Represents one value of a variable that can have one of many values. Clicking the button sets the variable to that value, and clears all other radiobuttons associated with the same variable. |
| Scale | Allows you to set a numerical value by dragging a "slider". |
| Scrollbar | Standard scrollbars for use with canvas, entry, listbox, and text widgets. |
| Text | Formatted text display. Allows you to display and edit text with various styles and attributes. Also supports embedded images and windows. |
| Toplevel | A container widget displayed as a separate, top-level window. |
Also note that there's no widget class hierarchy in Tkinter; all widget classes are siblings in the inheritance tree.
All these widgets provide the Misc and geometry management methods, the configuration management methods, and additional methods defined by the widget itself. In addition, the Toplevel class also provides the window manager interface. This means that a typical widget class provides some 150 methods.
