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.

Are the child's constraints being set on the parent? Maybe a screenshot
will help better understand the problem.
The SchemaFigure is your content figure, right? What are you doing in
paintFigure()? Set a border with insets of 20, 20, 20, 20 if you want a
thick border and it will resize correctly.

Yes, The schema figure is the content figure which extends freeformlayout. I
am including the snapshot. But the problem the bounds of the figure increase
only when I drag an element to the extremes but then my frame becomes a
problem, because the frame is just a rectangle on the schema figure. The
user should not be able to select it or delete it. It should be there. It
extends accordingly but the problem is the overlap of figure as shown in the
picture.
Please help me as what to do...

Create the frame as a border, instead of a rectangle figure, and you'll be
fine.

Thanks Pratik,
It worked for me. I used a margin border.

A MarginBorder just leaves some empty space so I don't know how you did
this. Did you subclass it? You should use a LineBorder.
