Docking through other applications

[zyrkiel]

Hello,

I am found a wired behavior that enables to dock a ads::CDockWidget in a Container that is not visible on the screen (hiden by an other application).
The issue can be reproduced with the simple example.

Screencast.from.2025-02-25.17-17-34.mp4

I think two solutions could be found:

• all the windows of the app should be shown if one if focus and that others are hidden by other applications
• the floating dock widget should not be docked/dropped in a hidden container. Overlay should not appear on top of other apps.

My config is:
Qt: 6.7.2 (through vcpkg official ports but it should not matter)
ADS: master
OS: Ubuntu 24.04
Debug

Should be fixed in master now

Unfortunately it's not working for me

Please test with Ubuntu 22.04

I can't right now. I only can test it on Ubuntu 24.04 and it's not working.
Thanks for having taken a look at it anyway.

On Unbuntu 22.04 it is working - so it seems to be an Ubuntu 24.04 issue

Have you try to reproduce with the Simple example?

It seems that CDockFocusController is only instantiated if FocusHighlighting flag is set.
That's not the case in this example.

Your solution seems to apply only if CDockFocusController is instantiated.

Yes, this is right - i fixed this in dock focus controllet

[zyrkiel]

Would it be possible to move the fix in the Manager (adding a connect with a CDockManager::onFocusWindowChanged slot) ?

[zyrkiel]

However, I just realize that the bug is still present if you have multiple floating dock container, one can be hidden and you still can dock an other floating dock container through the application hiding the first one.
The fix only works for the window that handles the manager.

But this is not an ADS issue because it works in Ubuntu 22.04. So there must be something wrong with Ubuntu 24.94

[zyrkiel]

It's working if the flag FocusHighlighting is set. It's not an Ubuntu 24 issue.
I don't know how your fix is working for the simple example since this example doesn't instantiate the CDockFocusController: the flag is not set.
Have you tested your fix on the simple example?
