thumbnail view not as Content outline view [message #224612]

I am looking for a way to create a thumbnail view of my GEF editor but not
as a ContentOulineView. Because I have already an outline view composed
of a tree of my diagram elements. So, I would like to have a thumbnail
view in a separate view. It is possible ? I know how to create a view, but
I dont know how to connect my view to my editor ?
For creating the view I need the root edit part of my GEF editor, but how
to give this root edit part to my view ?

Code of my view:
public void createPartControl(Composite parent)
{
// create canvas and lws
overview = new Canvas(parent, SWT.NONE);
LightweightSystem lws = new LightweightSystem(overview);

// create thumbnail
thumbnail =
new ScrollableThumbnail((Viewport) rootEditPart.getFigure());
thumbnail.setBorder(new MarginBorder(3));
thumbnail.setSource(
rootEditPart.getLayer(LayerConstants.PRINTABLE_LAYERS));
lws.setContents(thumbnail);
}

Thanks !

Sabri.

Simple way: Make the ContentOutlinePage layout on a SashForm. One part
of the sash will be your tree view and the other part the thumbnail
view. Giving part of code below.

public void createControl (Composite parent) {
sash = new SashForm (parent, SWT.VERTICAL);
getViewer().createControl(sash);

getViewer().setEditDomain(getEditDomain());
getViewer().setEditPartFactory(new <factory for tree>);
getViewer().setContents(<model>);
getSelectionSynchronizer().addViewer(getViewer());
Canvas canvas = new Canvas(sash, SWT.BORDER);
LightweightSystem lws = new LightweightSystem(canvas);
thumbnail = new ScrollableThumbnail(
(Viewport) ((ScalableRootEditPart) getGraphicalViewer()
.getRootEditPart()).getFigure());
thumbnail.setSource(((ScalableRootEditPart) getGraphicalViewer()
.getRootEditPart())
.getLayer(LayerConstants.PRINTABLE_LAYERS));
lws.setContents(thumbnail);

disposeListener = new DisposeListener() {
public void widgetDisposed(DisposeEvent e) {
if (thumbnail != null) {
thumbnail.deactivate();
thumbnail = null;
}
}
};
getGraphicalViewer().getControl().addDisposeListener(
disposeListener);
}

If you want full code, I can send it to your email id.

Hi Sebu,

Is it possible to share the complete code to my email id?
I understand it's a very old post and pulling the exact code may take time but it wouls be really helpful of you if in case you end up finding it.

Thanks a lot,
Vrushali.
