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