Hi all,

I have two types of figures placed in the same containment.

I need listen from one of these figures some graphical changes (in particular selection event or move event) of the OTHER figure.

Does anybody know if there is a way to do this?

Any idea would be very appreciated!!

Laura.

Hi Laura,

I would solve it like this:
1) take the root of the tree where all your classes are connected to.
2) place an addMouseListener or take one of the functions of the EditPart classes on the figure that changes.
3) Search trough the root the figure that you want to change and the figure who had an event. You have now the two classes in your hands and should be able to implement what you describe.

hope this helps,

Peter

Thanks a lot Peter!

The only problem than I have is when adding to the figure the MouseListener it works only when clicking in the border of the figure...I don't know why!!

If I click in the center of the figure it does not work Sad

The mouse listener can only be added to IFigures, I tried also FigureListener but with this I am not able to know the delta of the move action.

Any idea?

Thank you in advance.

Laura.

Hi Laura,

At the bottom of your EditPart classes in de diagram project, you will find stuff as:

	public class ControlPanel extends RectangleFigure {

		public ControlPanel() {
                ....
		private void createContents() { /* <= here you have to be !*/
			
		       RectangleFigure stopIndicator0 = new RectangleFigure();

this stopIndicator0 you can for example use to catch a mouse event. I do it with a factory who gets a reference to this object. But in order to make it simple I will inline the code, and you organize it as you want:

                final RectangleFigure stopIndicator0 = new RectangleFigure();
		stopIndicator0.addMouseListener(new MouseListener.Stub()
		{
			public void mousePressed(MouseEvent me)
			{
				if(stopIndicator0.getBackgroundColor()== ColorConstants.red){
					stopIndicator0.setBackgroundColor(ColorConstants.darkGray);
				} 
				else{
					stopIndicator0.setBackgroundColor(ColorConstants.red);
				}
			}
		});

Hi Marco,

if fact I had to detect when the user tried to move a figure inside another one.

I had installed a role policy "Drag&Drop" in the second figure and I receive this events in the this figure.

I don't know if it would suit you Smile

Best regards!

Laura.

Hello laura,

I suggest you installing listeners onto notation model objects so you'll
receive all the notifications concerning corresponding elements position/size..
