GXT TreeGrid Selection Event/Listener
In the evolution of the Ext GWT (GXT) framework, there seemed to have been some change as to how selection events of trees/tree grids can be intercepted. In release 2.2.1, the following approach works:
treeGrid.getSelectionModel().addSelectionChangedListener(new SelectionChangedListener() {
@Override
public void selectionChanged(SelectionChangedEvent se) {
GWT.log("selection changed from getSelectionModel");
}
});
The following approaches do not work:
store.addListener(Events.SelectionChange, new SelectionChangedListener() {
@Override
public void selectionChanged(SelectionChangedEvent se) {
GWT.log("selection changed");
}
});
treeGrid.addListener(Events.SelectionChange, new SelectionChangedListener() {
@Override
public void selectionChanged(SelectionChangedEvent se) {
GWT.log("selection changed");
}
});
