Are you expecting your "changeCurrent" slot to be called when navigating
the tree with keyboard? If so, thats where your error is. You connected the
pressed-signal of the treeview to that slot and the documentation clearly
states that this signal is emitted when a mouse button is pressed. If you
want to catch selection changes of your tree, you should look at the
signals of the QItemSelectionModel class. You can obtain the
selection-model from the treeview using the selectionModel member functions
