Parameters:

part	the editor part to observe

Returns:

true if the selection listeners were successfully installed, false if the selection listeners could not be installed

ControlListener de.fu_berlin.inf.dpp.editor.EditorListener.controlListener [protected]

Initial value:

 new ControlListener() {

        @Override
        public void controlMoved(ControlEvent e) {
            generateViewport();
        }

        @Override
        public void controlResized(ControlEvent e) {
            generateViewport();
        }

    }

Listens to resize events of the control, because the IViewportListener does not report such events.

boolean de.fu_berlin.inf.dpp.editor.EditorListener.isUnsupportedEditor [protected]

final KeyListener de.fu_berlin.inf.dpp.editor.EditorListener.keyListener [protected]

Initial value:

        public void keyReleased(KeyEvent e) {
            generateSelection();
        }

        @Override
        public void keyPressed(KeyEvent e) {
            
        }
    }

        }

        @Override
        public void mouseUp(MouseEvent e) {
            generateSelection();
        }

        @Override
        public void mouseDoubleClick(MouseEvent e) {
            
        }
    }

        @Override
        public void selectionChanged(SelectionChangedEvent event) {
            generateSelection();
        }
    }

ITextListener de.fu_berlin.inf.dpp.editor.EditorListener.textListener [protected]

Initial value:

 new ITextListener() {

        @Override
        public void textChanged(TextEvent event) {

            String text = event.getText();

    }
