Problem with TextCtrl focus since Windows 10

Newbie Help
1

Hallo,
i’m using wxpython now since a few years, mostly with Ubuntu. Now, i tried my code again under Windows and since Windows 10 i do have a problem the focus of the TextCtrl objects.
If i select a TextCrtl with the mouse, it gets framed (on Win 10), or blue underlined (Win 11), and it stay this way, even when i select an other TextCtrl. This also happens for inactive TextCtrl windows. AND i’m not able to return the focus to one of those windows with the cursor. I can use the TAB-key to get the keyboard input back to those TextCtrl windows, then the cursor still stays at his last position, whereas the letters appear in the TAB-selected window.

I’ve searched the web for those issues, but really got no results. From this search i got the brief idea it may depend on the ‘voice output’-focus of windows, but turning off the voice output didn’t solve the problem.

So it may be rather a windows-problem then a wx-problem, but if anyone has an idea, he is welcome!

Thanks a lot in advance,
Andreas K.

I wonder if you have the controls in panel? Best of my knowledge for the tabs/returns/mouse to act normal they have to be in a panel.

Hallo,
i’ve changed my code to sizers and therefore i do not use a panel at the moment (at least not expicitly). But for some dialogs, i still have my hardcodet panel code. I just tested this old code and yes, it has the same behaviour.

Thanks for your answer.

well, you haven’t got a runnable code, have you? but if you have please put it into </> icon and some fog may lift :face_with_peeking_eye:

Thanks, you’re right, i’ve to strip it down to get a clear view on the problem. Hopefully i’ll get a small executable example of the problem.
Think that might even be the best way to track the problem, as i now noticed, the i have smaller dialogs, where the problem does not occur, the keyboard focus and the cursur focus are synchronised correctly.
The whole time i assumed it to be a principal windows or wx problem. But the problem really seems to lie in my code.
I’ll come back to you, when i’ve stripprd down the problem.

Hallo,
now i have two examples extracted from my code, one where the problem occurs (TestDialog_Ko) and a second, where everything work OK (TestDialog_OK):

Your EVT_KILL_FOCUS handler is inhibiting some of the default behaviour of the control. Add event.Skip() to the handler.

Thanks!!!
Sometimes the solutions are really simple! As i invented the ‘On_KillFocus’ method in the parent class of all my dialogs, the problem occured really widespread in my code!

By the way: in all other event triggered methods. i have an ‘event.Skip()’ in my code.
Thanks a lot for all, i carried this problem with me now for nerarly 1 1/2 years.

Cheers
