| | 80 | A ComboBox is like a combination of an edit control and a listbox. It can be |
| | 81 | displayed as static list with editable or read-only text field; or a drop-down |
| | 82 | list with text field; or a drop-down list without a text field. |
| | 83 | |
| | 84 | This example shows both a preset ComboBox and one that is dynamically created |
| | 85 | (that is, it is initially empty but then we 'grow' it out of program-supplied |
| | 86 | data). The former is common for read-only controls. |
| | 87 | |
| | 88 | This example also shows the two form factors for the ComboBox. The first is more |
| | 89 | common, and resembles a Choice control. The latter, although less common, shows |
| | 90 | how all the values in the ComboBox can be visible, yet the functionality is the |
| | 91 | same for both. |
| | 92 | |
| | 93 | Finally, this demo shows how event handling can differ. The first ComboBox is set |
| | 94 | up to handle EVT_TEXT_ENTER events, in which text is typed in and then ENTER is |
| | 95 | hit by the user. This allows the user to enter a line of text which can then be |
| | 96 | processed by the program. EVT_TEXT can also be processed, but in that case the |
| | 97 | event is generated every time that the user hits a key in the ComboBox entry field. |
