[wxruby-users] Making a frame stay on top sometimes

[Eric Rubin]

Thanks, but I just noticed that there is a Window#set_window_style_flag
which seems like it would do what I want.  I think I'll give that a try.  If
it doesn't work I might try your two frames solution.

 From my reading of wxWidgets discussions, there's no way to change the 
style flags of a Window (inc Frame) after it's been created. This is 
because changes are not guaranteed to be honoured on all platforms.

The way round this in your circumstance might be to have two frames, 
with one hidden and one shown at any time. One has the STAY_ON_TOP 
style, the other not. When you want to change the STAY_ON_TOP behaviour:

1) hide the currently shown frame
2) reparent that frame's top-level content (eg Panel) to the other frame
3) move the frame you're about to show to the same size and position
4) show the previously hidden frame
