Hello all!
I want to make a GEF editor allowing the user to lay out graphical
objects on a display, so the diagram area of the editor must be of a
fixed size. The bounds of the diagram in pixels are set upon the editor
creation, when the user chooses the screen resolution, and later they
probably never change.
Can somebody tell me how to accomplish this?
The problem is that by default the sizes are practically unlimited -
they grow when figures are resized or new ones are added so that they
don't fit within the bounds anymore. This behaviour is inappropriate for me.
Thanks in advance,
Ilya

IIRC this is because of the FreeFormLayout of the root editpart. You want
to use a different layout. FreeForm expands to fit the bounds of the
contents.

As I wrote in the previous answer I tried some other layers and layouts,
for instance, the combination of
ScalableLayeredPane, XYLayout, and ScalableRootEditPart instead of
FreeformLayer, FreeformLayout, and FreeformGraphicalRootEditPart
and still the diagram sizes were unlimited, though they could grow into
only two directions instead of four.
Setting the maximumSize property of the diagram Figure didn't help either.
