Re: Making a window/application always on bottom
Message 1 in thread
Hi Allen
I don't know of anything within Qt... but...
It may be possible to intercept the WM_MOUSEACTIVATE message for your top
level window and discard it.. that way your window won't be activated when
you click on it, and then it shouldn't be raised. Looking at the Win32
documentation for Z order and SetActiveWindow doesn't reveal anything for
keeping windows on the bottom.
Another option to explore would be Active Desktop, which will allow you to
embed an active-x control as the desktop background (there might be some 3rd
party way of making any window the desktop backrgound, not sure).
Hope that helps
Ross.
