GraphicalEditorWithFlyoutPalette without scroll bars [message #510970]

The title pretty much says it. I have a (custom subclass of) GraphicalEditorWithFlyoutPalette that has scroll bars, because the figure inside it is too large. How can I remove the scrollbars. Obviously the default graphical viewer for GraphicalEditorWithFlyoutPalette is always a ScrollingGraphicalViewer, overwriting this leads to exceptions.

Presumably you tried over-riding the following method in your editor?:

protected void createGraphicalViewer(Composite parent);

But if your figure is big then removing the scrollbar will make you figure visible partially or not visible at all...

The best way would be...

((ScalableRootEditPart*) getGraphicalViewer().getRootEditPart()).getZoomManager().setZoomAsText(ZoomManager.FIT_ALL)

*What ever is your rooteditpart.

still if your figure is too large the result will not be viewable...

In fact, I tried to override configureGraphicalViewer(). I don't quite get the difference between create..., initialize... and configureGraphicalViewer(). I added the line suggested by Philipp, however my figure is not shown at all any more. It is indeed big, but is ok, if it is shown only partially. By the way, I have a ScalableFreeformRootEditPart
Any idea how to remove the scroll bars, but with having the Figure (containing a large image) still been drawn?

When I said to over-ride createGraphicalViewer(Composite parent) in your
editor I meant like this:

protected void createGraphicalViewer(Composite parent) {
GraphicalViewer viewer = new GraphicalViewerImpl();
viewer.createControl(parent);
setGraphicalViewer(viewer);
configureGraphicalViewer();
hookGraphicalViewer();
initializeGraphicalViewer();
}

When I add that to my Editor I get no scroll bars.

Does it also enshure that the figure will be scaled down to fit the visible area...??

@Ben Wecker
Did you try the zoom manager part...

((ScalableFreeformRootEditPart
) getGraphicalViewer().getRootEditPart()).getZoomManager().setZoomAsText(ZoomManager.FIT_ALL)

ScalableFreeformRootEditPart also has a getZoomManager method...

No. But the original poster said "...but is ok, if it is shown only
partially."

Philipp, thanks a lot! Overriding the createGraphicalViewer() method in the way that you suggested worked perfectly for me! I do not need the image to be scaled.
