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. + +This example shows both a preset ComboBox and one that is dynamically created +(that is, it is initially empty but then we 'grow' it out of program-supplied +data). The former is common for read-only controls. + +This example also shows the two form factors for the ComboBox. The first is more +common, and resembles a Choice control. The latter, although less common, shows +how all the values in the ComboBox can be visible, yet the functionality is the +same for both. + +Finally, this demo shows how event handling can differ. The first ComboBox is set +up to handle EVT_TEXT_ENTER events, in which text is typed in and then ENTER is +hit by the user. This allows the user to enter a line of text which can then be +processed by the program. 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. + +""" + +if __name__ == '__main__': + import sys,os + import run + run.main(['', os.path.basename(sys.argv[0])]) +
