Hello list!
With respect to the pop up window not being in the DWSC_UPPER class the
problem seems to
be that gdk_window_set_type_hint() is not fully implemented. I have added the
handling for
GDK_WINDOW_TYPE_HINT_POPUP_MENU:

With this patch the dfbdump output seems ok:
-----------------------------------[ Windows of Layer 0

Reference FID . Refs X Y Width Height Opacity ID
Capabilities State & Options
--------------------------------------------------------------------------------------------------
0x00000018 [ 1] : 6 2, 2 71 x 81 0x00 4 ^
alphachannel FOCUSED
0x00000014 [ 1] : 3 0, 0 75 x 45 0xff 2 ^ alphachannel
0x00000017 [ 1] : 1 -100, -100 10 x 10 0x00 3 - input only
0x00000012 [ 1] : 2 0, 0 640 x 480 0x00 1 - alphachannel
I have the following open questions:
- What is an "input only" window?
- Who's creating this extra GdkWindow just for input and why?
- Why are DirectFB windows not collected (freed) after they are closed?
For example, after closing a dialog, it continues appearing in the dfbdump
output.
Other problems
- The dropdown list loses focus after being clicked. You must move the mouse
slightly for it to gain focus again.
- Why does the combo box not use GDK_WINDOW_TYPE_HINT_COMBO, rather than
GDK_WINDOW_TYPE_HINT_POPUP_MENU?
(Ok, this is probably a gtk+ question)
