Hide window for screen capture - using WDA_EXCLUDEFROMCAPTURE maybe optional?

[bn45hkurr0y4]

Is your feature request related to a problem? Please describe.
Sometimes I turn on screen sharing in Discord and open the CopyQ window. It contains confidential information.

Describe the solution you'd like
Using SetWindowDisplayAffinity with args WDA_EXCLUDEFROMCAPTURE/WDA_MONITOR (if use windows)
There is also a similar api for MacOS.
This feature can be made optional.

Describe alternatives you've considered
none

Good idea. Though it would make it a bit harder to shared screenshots in bug reports.

Thanks, for the suggestion and sharing the details! I will look into it.

Feature implemented in the dev build here: https://ci.appveyor.com/project/hluk/copyq/builds/52818546/artifacts

Thank you, the function works, but for some reason the context menu is no longer displayed correctly (in the tray and in the program itself).
When opening the context menu, the program freezes and only responds after the window becomes inactive.

I checked this on the main machine with many elements and on a virtual machine.

Thanks for testing!

The app applies the settings to all its "windows" which also include menus. I could change that, so only the main window is affected, even though the tray menu also lists clipboard history by default. Would that make sense?

I don't quite understand why the program freezes when I open the context menu.
It freezes when I open it from the menubar (File, Edit, etc. buttons).
I sent you a GIF showing how it works (I click on the items, but it doesn't respond).
It would be nice if the context menu in the tray could also be hidden (since it also contains entries from the clipboard).

This is on VM(WinApi hide windows)

I don't quite understand why the program freezes when I open the context menu.

Me neither, it could be Qt bug. I'm trying to set it just for the main window, perhaps it will affect also menus.

Does this build work better?
