[ve-dev] Question about overriding EditPart.

[Hung V Lam <hungvlam@xxxxxxxxxx>]

Hello,
I have a question about override Edit
Part in VE.

If we have a custom composite looks
something like this, is it possible to render in VE?

Some explanations of CustomComposite
:
1.  The CustomComposite has a private
settings of type Properties.
2.   It has a render() method that
constructs all its children.
3.   CustomControl is another custom
Composite.
4.   The constructor of CustomControl
does nothing but set the layout.
5.   The render() method of CustomControl
creates a SWT widget based on the settings.
6.   The "settings" that's
passed to each CustomControl is from CustomComposite.

We attempted to accomplish this by creating
an Edit Part (eg: create a override file, and our own EditPart that extends
CompositeGraphicalEditPart for our CustomControl), but ran into these problems:
1.  How do we initialize "settings"
of CustomComposite when the *.java file is opened in VE editor, and before
VE attempts to display this composite.    We need to send this
"settings" to each of CustomControl in render() method.
2.  How can we tell VE to construct
the figure when the render() method is called for each CustomControl.  

Hope this makes sense.  Thank you.

        private

CustomComposite(Composite parent,int style)
        {
         
      super(parent,style);
         
      initialize();
        }

        {
         
      this.settings = settings;
        }

        {
         
      this.setSize(new Point(548, 223));
         
      render();
        }

        {
         
      CustomControl control1= new CustomControl(this,SWT.NONE);

      CustomControl control3 = new CustomControl(this,SWT.NONE);
         
      control3.setSomeSettings(settings);  
               
     
         
      control3.render();
         
      
         
      CustomControl control4 = new CustomControl(this,SWT.NONE);
         
      control4.setSomeSettings(settings);
