I have now tested and indeed this solved the problem with
GtkFileChooserButton. But I wasn't as luck with GtkCombobox, which inherits
from a GtkBin and adds a GtkCellView as a child. Neither without any
GdkWindow. It does add a button, which is connected to the GtkBin through as
gtk_widget_set_parent. But this button does not appear in
gtk_container_get_children(). Sigh. Gtk does have transparency issues...
Any ideas?
