Hi all,
I am trying to make changes to the schema diagram editor example to get a
better understanding of gef. I need to add af frame to the editor on which
my figures would appear. I am able to do this by adding a recatngular figure
to the schemafigure. Schemafigure extends FreeformLayer. So the frame
appears on it.
The class schemafigure is as follows:
public class SchemaFigure extends FreeformLayer
{
public SchemaFigure()
{
setOpaque(true);
setBorder(new LineBorder(ColorConstants.white, 1));
}
protected void paintFigure(Graphics g)
{
Rectangle r = getBounds().getCopy();
r.translate(20, 20);
g.setLineWidth(2);
g.drawRectangle(r.x, r.y, r.width - 40, r.height - 40);
g.drawRectangle(r);
}
}
My problem is, when I add figures at the edges, the frame and the editor
expands, which is desired, but my figure intersects the frame. How can I
validate and expand the frame at this point so that the figure lies withing
the frame and not over it.
Thanks in advance,
Binti

If I understand you correctly...
when you do sth to your models to impl adding a child figure onto your
frame, do you recalculate the size of the frame?

Sorry. Just have a look at logic example...
Do you set a FreeformLayout instance as the LayoutManager of the frame?

As I mentioned the schemafigure extends a freeform layer and it extends when
the model becomes largea and the frame on it expands as well. I am trying to
recalculate the size of the frame and resetting its bounds, but it is not
doing so....i try to get the freeformextent and set it again. even if I use
setsize or setpreferred size for schema figure it does not show....it is
only following the default behaviour of expansion vertically and
horizontally upon adding childs. How can I control this behaviour?
Thanks in advance,
Binti
