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.
|
|
|
|
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.
