Hi,
I am making my own Navigator view Plugin for eclipse.
View consists of a TreeViewer.
The issue is I want to refresh(automatic) this view in case of any
addition/deletion/change to the resource workspace.
I refresh my TreeViewer in the code like this:
IResourceChangeListener listener = new MyResourceChangeReporter();
ResourcesPlugin.getWorkspace().addResourceChangeListener(listener);
....
private class MyResourceChangeReporter implements IResourceChangeListener {
public void resourceChanged(IResourceChangeEvent event) {
try{
treeViewer.refresh();
}
catch(Exception e){
e.printStackTrace();
}
}
}
//inner class ends
I am able to add the resources, but while deleting a Project I get exception:
