 | |
| 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.
