How to FIT_ALL for newly opened file? [message #168712]

I'm using ScalableFreeformRootEditPart and I'd like to automatically do a
FIT_ALL when the editor is initially opened.

I've tried the following right after InitializeGraphicalViewer():

((ScalableFreeformRootEditPart)viewer.getRootEditPart()).get ZoomManager().se
tZoomAsText(ZoomManager.FIT_ALL);

but I end up with my graphics stuffed into a 36x36 square because that's how
big the client area claims to be.

If I don't do anything, the initial view will be zoomed in too close to be
meaningful. (My coordinates span values in the thousands both positive and
negative - so I'm depending on the ScalableFreeformRootEditPart to scale it
all to fit on the screen.)

Where's a better place for me to perform my initial FIT_ALL?

Thanks,

Jim

You probably need to wait until your editor's control has been resized.

I've solved my problem as follows:

In configureGraphicalViewer(), right after setting the root edit part for
the viewer, I call
root.getFigure().setVisible(false);
to ensure that none of the graphics will be drawn.

Then in my WorkbenchAdvisor.openEditor(), once my editor is opened, I get
the ZoomManager and perform the FIT_ALL, then I call setVisible(true) on the
root figure so that it will be displayed.
