Hi!
I have a custom layout to be applied to a compartment figure. This is a
customized XYLayoutEditPolicy, and I want to apply it when I move certain
elements, so I catch the ChangeBoundsRequest in the getCommand function. I
do a super.getCommand(request), and in and in a certain point I have a
ClassCastException. This is the exception:
************
java.lang.ClassCastException:
org.eclipse.gmf.runtime.draw2d.ui.figures.ConstrainedToolbar Layout cannot be
cast to org.eclipse.draw2d.XYLayout

************
Failed when cast a ConstrainedToolbarLayout to a XYLayout. The code that
makes this exception is the following (in XYLayoutEditPolicy):
************
protected XYLayout getXYLayout() {
if (xyLayout == null) {
IFigure container = getLayoutContainer();
xyLayout = (XYLayout)container.getLayoutManager();
}
return xyLayout;
}
************
This 'container' IFigure is the compartment, and it has a BorderLayout, I
don't know if this has anyting to do with this exception...
Anybody can help me please?
Thanks to everybody.
