[RFE} Add onselectionchanged event handler for tree widgets to notify when tree items are added/removed from the selection. This might also apply to other widgets which support multiple selection. Rationale: I am trying to maintain multiple selection in a tree of widgets and a form view of the same widgets. I also need to synchronize a property inspector. The current tree.onselected event only gives the total current selection. This is murder when you need to know when an item is de/selected.
are you using tree or outliner?
I am using the tree control. I suppose that once mutation events are in I could listen for changes to the "select" attribute. In the meanwhile I clone the selection list and then look for additions and removals.
I have reconsidered this request. Onselect works fine for most users. It took about 20 lines of code to maintain my own selection list and to compare it with the selectedItems list in the onselect event. The differences generate my own selection change events. When mutation events arrive a more direct approch will be available. Please consider this item closed.
Mutation events are online.
