How to find out the current widget size in tkinter?

Question

I'm using Python and Tkinter, and I need to know the current dimensions (width, height) of a widget.

I've tried somewidget["width"], but it returns only a fixed value, and is not updated whenever the widget size changes (e.g. when the window is resized).

Answer 1

Use somewidget.winfo_width() and somewidget.winfo_height() to get the actual widget size, the somewidget['width'] property is only a hint given to the geometry manager.
