TreeViewer: getText before treeExpanded [message #452261] Wed, 16 March 2005 11:03 Go to next message

I'm using a TreeViewer and, in my application, the elements' labels depend
on the selected element. So, I want to be able to know when the user
expand an element, do some processing and, then, give the children's
labels. But getText() (in LabelProvider) is called for the children of the
expanded element before treeExpanded() (in ITreeViewerListener). Is there
a way to notice the expansion before the children are shown?

Does anybody know the answer to this question (now 8 years after)?
I have the same problem: how to get the eventhandler (listener) for the event after the default behavior is executed.
In other development enviroments/libraries, there was a explicit differenciation: something like afterExpand vs. beforeExpand.
