Python Tkinter Toplevel
Advertisements
Toplevel widgets work as windows that are directly managed by the window manager. They do not necessarily have a parent widget on top of them.
Your application can use any number of top-level windows.
Syntax:
Here is the simple syntax to create this widget:
w = Toplevel ( option, ... )
Parameters:
options: Here is the list of most commonly used options for this widget. These options can be used as key-value pairs separated by commas.
| Option | Description |
|---|---|
| bg | The background color of the window. |
| bd | Border width in pixels; default is 0. |
| cursor | The cursor that appears when the mouse is in this window. |
| class_ | Normally, text selected within a text widget is exported to be the selection in the window manager. Set exportselection=0 if you don't want that behavior. |
| font | The default font for text inserted into the widget. |
| fg | The color used for text (and bitmaps) within the widget. You can change the color for tagged regions; this option is just the default. |
| height | Window height. |
| relief | Normally, a top-level window will have no 3-d borders around it. To get a shaded border, set the bd option larger that its default value of zero, and set the relief option to one of the constants. |
| width | The desired width of the window. |
