wxDialog loses focus at show

[Сергей Коныгин]

Hello!

Recently I noticed that my dialog windows have no focus after calling ShowModal(). Therefore I need to click the left mouse button in order to activate window. There are no visible problems except one more mouse clicking. Probably this strangeness appears since version 3.2.2.1.

I have no idea how to solve this problem.

Me neither, so I can just recommend the usual:

1. Please try to reproduce the problem with minimal changes to the dialogs
sample (which already has all sorts of dialogs).
2. If this worked before, please try to run git-bisect to find the commit
in which is stopped working.

If you can do at least one of the above, please open an issue for this
problem and attach the diff to the sample (for (1)) or mention the commit
you found (for (2)) and, of course, in any case please provide your
platform details, i.e. at the very least which OS do you use.

Thanks,
VZ

Hi,

While debugging my application I have noticed the MouseMove events for the main window are still called even if there is another window shown over with ShowModal().

I have avoided unwanted behaviour by calling Freeze (before the ShowModal() call) for the main window ... 

I do not know when this "bug/behavior" was introduced.

I currently tested it for MacOS only.

best regards,

Mihai

Hi,

I just tested it on Windows, and the problem is not manifesting.

So, it is specific for MacOS.

The dialog shown with ShowModal() does not get focus if I do not click on it. Because of that, mouse events (like mouse move) are still generated for window behind it ...

Hi,

The worst part of this problem is that even after calling wxMessageBox, the mouse move events are still generated for the window behind it.

So, I had to unbind all mouse move messages before calling ShowModal and wxMessageBox and then to bind them again.

This problem appears only on MacOS. I have not noticed it in the older versions of wxWidgets.

best regards,

Mihai

Sorry, I really can't add much more to what I had written previously. If
you can, please try running git-bisect to find when this broke and open an
issue with this information.

Thanks,
