Igor Korot a216806c99 Allow modifying wxComboBox from its CLOSEUP handler with wxGTK2
Doing this resulted in GTK errors about invalid iterators, so postpone the
generation of the CLOSEUP event for slightly later to allow changing the
combobox contents from it with GTK+ 2 (this is not necessary with GTK+ 3).

Also add a demon of a dynamic combobox, creating and destroying its items on
the fly, to the widgets sample.

Closes #17223.
