An ExtendedComboBox looks much like a ComboBox, but allows for any view |
|
| 5443 | 56 |
to be popped up |
57 |
(in contrast to a ComboBox, which has a hardWired selectionInListmenu). |
|
58 |
||
| 1281 | 59 |
The popped view may optionally be decorated with scrollBars. |
60 |
As a side effect, an ExtendedComboBox with a SelectionInListView or Menu |
|
61 |
can now be used as a replacement for ComboBoxes when long-lists are to be shown, |
|
| 5443 | 62 |
since those can now be scrolled or defined as hierarchical lists. |
