Getting a Signal when the current selection in a QTreeView changes.

[Doug Broadwell]

I have a QTreeView connected to a QDirModel. I need a signal whenever the user changes the highlighted item in the tree view - whether by mouse or by up/dn arrow keys (I have to change the active state of a button depending upon if it is pointing at a directory or a file). I cannot find any such signal in either the QTreeView nor the QDirModel.

How to implement?

Thanks,
Doug

See the signals from QItemSelectionModel( for example, the currentChanged signal). You must connect to those.
You can access the selection model for your view with QTreeView::selectionModel().
