I just started to use floating toolbars. I checked the float and keep on top checkbox. However if i start opus Image viewer they also keep on top above it. Is this normal behaviour, since img viewer has a different window class it should behave like that imo.
Is there a way to change this?
You want floating toolbars on top of some windows but not on top of the image viewer windows?
Only on top of the opus lister.
If I set it to float and keep on top it's applies only to opus not other windows. I don't know if that is the way it should be.?
There are three "on top" modes for Opus windows:
[ul][li]On Top is the standard Windows "always on top" mode where such a window will be on top of all windows (except other "always on top" windows or special cases like full-screen windows).
[/li]
[li]On Top of Opus is a special mode where such a window will be on top of other Opus windows (unless they're on-top in some way) but won't be stuck on top of non-Opus windows.
[/li]
[li]Off, which is the usual/standard behaviour windows.[/li][/ul]
It sounds like you're using the On Top of Opus mode for your floating toolbars. In that case they'll appear on top of the Opus viewer window, since it's part of Opus.
Yes I see it now too that there are 3 options but it isn't exactly convenient if you're viewing images in fullscreen mode. So it would be logical to have an extra option to exclude opus.
On top of Opus excluding Opus? umm...
You could set the viewer to be on-top as well. I think that'll solve the problem.
Click the viewer's window icon (i.e. top-left of the window frame) to find the option.
Yes that solved the problem..haha 
. How I couldn't think of that.
You know what I meant.. 
on top of opus exclude opus img viewer..
