Re: [directfb-dev] GtkComboBox drop down list covered by GtkDialogs

[Jesus Ruiz de Infante <jesus ruizdeinfante hale at>]

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 ]-----------------------------------------

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)
