tkinter and Qt do not "activate" buttons by pressing the ENTER key with the button highlighted / in focus
|
|
This demo will enable the application to click on a button if the button has focus (is highlighted) and the
|
|
user presses the ENTER key.
|
|
NOTE that the SPACE BAR works correctly out of the box with both tkinter and Qt. If a button has focus and
|
|
you press the space bar, then tkinter and Qt will both consider that a button click. But not so with the ENTER
|
|
key.
|
|
|
|
The solution is for your program to read the keyboard presses and act upon those directly. It's trivial logic
|
|
in the end:
|
|
1. Get a key press
|
|
2. See if the key is the ENTER key
|
|
3. Find the Element that currently has focus
|
|
4. Click the Button if the Element with focus is a button
