Hi all,
When I create a "container" editpart, I will create a Figure object that
allows user to add objects into it. However the default bounds for Figure is
0, 0, 64, 36. Is it possible to determine the "viewer's" actual size on
start up, such that the bounds of the Figure could be overridden?
Thanks!!

Hi Randy,
Thanks for your help. Below is the "createFigure" code fragment in the
"container" editpart
protected IFigure createFigure() {
Figure f = new Figure() {
public void setBounds(Rectangle rect) {
int x = bounds.x, y = bounds.y;
boolean resize =
(rect.width != bounds.width)
|| (rect.height != bounds.height);
if (isVisible() && (resize)) {
erase();
}
bounds.width = rect.width;
bounds.height = rect.height;
if (resize) {
fireMoved();
repaint();
}
}
};
f.setLayoutManager(new XYLayout());
return f;
}
and the viewer i am using is ScrollingGraphicalViewer with
ScalableRootEditPart. For the "child" editpart (i.e. the figure added to the
container), the following is the code fragment for refreshVisuals()
protected void refreshVisuals() {
ChildUIModel childUIModel =
(ChildUIModel ) getModel();
Rectangle r =
new Rectangle(
childUIModel .getX(),
childUIModel .getY(),
-1,
-1);
((GraphicalEditPart) getParent()).setLayoutConstraint(
this,
getFigure(),
r);
}
What I want is that when childUIModel.getX() or childUIModel.getY()
returns -1, those values will be set such that the newly added child UI
figure will reside in the middle of the "container" figure. Is there any way
to do that? Or am I going on the wrong track? Thanks!!
