Non-activating panel

General
1

I’m trying to create a floating window that behaves like a PopOver, on Win and Mac desktop targets. The major difficulty is that it should be non-activating, so that it does not send the main window to the background when open.

On Mac Big Sur, I tried to configure the NSPanel with becomesKeyOnlyIfNeeded = True, but it does not seem to do anything. Perhaps it also needs some other property or window style/level, but I couldn’t find anything online.

In the Open event:
#if TargetCocoa then
declare sub setBecomesKeyOnlyIfNeeded lib “Cocoa” selector “setBecomesKeyOnlyIfNeeded:” (obj_id as Integer, value as Boolean)

setBecomesKeyOnlyIfNeeded self.handle, true
#endif

I haven’t had much success on Windows either. I tried setting the WS_EX_NOACTIVATE flag in the Window.Constructor to no avail.

Any help would be much appreciated!

If you have the MBS plugins you might be able to use OverlayMBS.

Yes, OverlayMBS would be non-activating and is a great class, but I’d much rather prefer to use a regular window that could embed container controls.
