ListView as a multi-select combo box
We would like to implement a multi-select combo box. We need a widget that uses a ListStore<T>. Using a TextButton with a Menu of CheckItems does not allow us to have a backing store, even though the physical appearance does meet our requirements.
We could implement this with a ListView however then we don't get check boxes. The user needs to hold CTRL to multi-select. Are there other approaches you can recommend? Is there a way to have check boxes appear in the ListView?
It seems like this feature existed in GXT previously: CheckBoxListView in GXT 2.2.5.
