Hello!
In my application I'm able to change the figure of an editpart from a
rectangle to a circle and vice versa.
I'm achieving this by overriding the method setFigure(IFigure newFigure)
like this:
@Override
protected void setFigure(IFigure newFigure) {
if (figure != null) {
oldGeometryType = getExhibit().getGeometryType();
unregisterVisuals();
IFigure parentFigure = figure.getParent();
int index = parentFigure.getChildren().indexOf(figure);
parentFigure.remove(figure);
figure = newFigure;
parentFigure.add(figure, index);
registerVisuals();
} else {
super.setFigure(newFigure);
}
}
I call setFigure every time the property geometryType in my model
changes. This check is done in refreshVisuals of the editpart. Here is
some code of refreshVisuals():
@Override
protected void refreshVisuals() {
String geometryType = getExhibit().getGeometryType();
....
Rectangle bounds = null;
if(geometryType.equals(VisualExhibit.GEOMETRY_TYPE_BOX)) {
bounds = new
Rectangle(UnitConversion.toPoint(getExhibit().getPosition()) ,
((RectangleFigure)getFigure()).getVirtualBounds().getSize()) ;
} else
if(geometryType.equals(VisualExhibit.GEOMETRY_TYPE_CYLINDER) ) {
bounds = new
Rectangle(UnitConversion.toPoint(getExhibit().getPosition()) ,
(getFigure()).getSize());
}
((GraphicalEditPart) getParent()).setLayoutConstraint(this,
getFigure(), bounds);
getFigure().repaint();
super.refreshVisuals();
}
My problem is, that when the figure changes the bounding box of the old
figure is still drawn once. After that the bounding box for the figure
is correct (for example when I resize the figure or change the position).
So how can I achieve that if the figure of an EditPart changes, the
bounding box appears correct? I also tried to use
getFigure().setBounds(bounds) in refreshVisuals of the EditPart. But
that wasn't successful too...
So may somebody made the same experiences and can provide me with a
solution or somebody has an idea what I'm doing wrong?!
Thanks in advance
Robert

Thanks Randy. It works fine.
For those who are interested, I call deactivate() before and activate()
after setting the new Figure.
Regards
