Hi all:
I want to embed a ScrollingGraphicalViewer viewer into a FormPage so
that the viewer occupies the available space. To this end, I do the
following:
protected void createFormContent(IManagedForm managedForm) {
Composite container = toolkit.createComposite(scrolledForm.getBody());
container.setLayout(new GridLayout(1,true));
// viewer
ScrollingGraphicalViewer viewer = new ScrollingGraphicalViewer();
Control viewerControl = viewer.createControl(container);
Diagram diagram = new Diagram();
Ellipse ellipse = new Ellipse();
ellipse.setLocation(new Point(150, 50));
diagram.addChild(ellipse);
viewer.setContents(diagram);
viewerControl.setLayoutData(new GridData(GridData.FILL_BOTH));
}
But when I run the application, nothing in the formpage. Anybody can
help me to solve this problem?
Thanks for any pointers.

Hi,
Did you set the editpart factory for the viewer? Did you create the root
editpart? I don't see that in your snippet.
If that doesn't help debug the #setContents(), check that editparts and
figures are created. IF yes, put a breakpoint in the ellipse figure paint
method or diagram figure paint method... check if they are being painted
and where...
Hope this helps.
Cheers,
Alex
