89 | overview = """\ | |
90 | A ComboBox is like a combination of an edit control and a listbox. It can be | |
91 | displayed as static list with editable or read-only text field; or a drop-down | |
92 | list with text field; or a drop-down list without a text field. | |
93 | ||
94 | This example shows both a preset ComboBox and one that is dynamically created | |
95 | (that is, it is initially empty but then we 'grow' it out of program-supplied | |
96 | data). The former is common for read-only controls. | |
97 | ||
98 | This example also shows the two form factors for the ComboBox. The first is more | |
99 | common, and resembles a Choice control. The latter, although less common, shows | |
100 | how all the values in the ComboBox can be visible, yet the functionality is the | |
101 | same for both. | |
102 | ||
103 | Finally, this demo shows how event handling can differ. The first ComboBox is set | |
104 | up to handle EVT_TEXT_ENTER events, in which text is typed in and then ENTER is | |
105 | hit by the user. This allows the user to enter a line of text which can then be | |
106 | processed by the program. EVT_TEXT can also be processed, but in that case the | |
107 | event is generated every time that the user hits a key in the ComboBox entry field. | |
