Re: Re: wx.BusyInfo does not stick to parent, stays on top of other applications

Sorry for taking so long to reply on this. My solution was to ditch 
wx.BusyInfo, because it simply does not work as I think it should. I 
also considered the AGW solution, but that was very different from the 
native look-and-feel of the GUI, so I didn't look into this any further.

Here's how I made the "busy display" work for my case. My application 
works with a "main" window. So I decided to implement the "busy 
display" as part of my main window (code snipped below). Now I just use 
calls to frame_main.busy_box.activate( ... ), 
frame_main.busy_box.deactivate( ... ) and frame_main.busy_box.setup( 
.. ) to control the busy display from the main thread or from the 
separate long-running thread (wrapped into wx.CallAfter where 
necessary).

Cheers
Matthias
