An ExtendedComboBox looks much like a ComboBox, but allows for any view |
|
| 5443 | 58 |
to be popped up |
59 |
(in contrast to a ComboBox, which has a hardWired selectionInListmenu). |
|
60 |
||
| 1281 | 61 |
The popped view may optionally be decorated with scrollBars. |
62 |
As a side effect, an ExtendedComboBox with a SelectionInListView or Menu |
|
63 |
can now be used as a replacement for ComboBoxes when long-lists are to be shown, |
|
| 5443 | 64 |
since those can now be scrolled or defined as hierarchical lists. |
