Question

Is it possible in GWT to had a handler that detects that the knob pf SplitLayoutPanel is been drag or pressed?

Thanks for the help.

I think, you can do it by overriding onResize() inherited method of DockLayoutPanel:

  SplitLayoutPanel splitLayoutPanel = new SplitLayoutPanel(){
            @Override
            public void onResize() {
                super.onResize();
                Window.alert("resized");
            }
        };
