Core Windows/Controls → ComboBox

wxPhoenix

Overview = """\

A ComboBox is like a combination of an edit control and a listbox. It can be
displayed as static list with editable or read-only text field; or a drop-down
list with text field; or a drop-down list without a text field.
Normally, ComboBox have be created for read-only controls. Meanwhile it can be
dynamically created (that is, it is initially empty but then we 'grow' it out of
program-supplied data).
Finally, this demo shows how event handling can differ.
EVT_TEXT_ENTER events, in which text is typed in and then ENTER is hit by the user.
EVT_TEXT can also be processed, but in that case the event is generated every time
that the user hits a key in the ComboBox entry field.
