How to use NonResizableEditPolicy? [message #187540]

Hello.

I want to make a figure to be not resizeable. I found the EditPolicy
NonResizableEditPolicy. I tried to install this Policy for the
corresponding EditPart via:
protected void createEditPolicies() {
installEditPolicy(EditPolicy.SELECTION_FEEDBACK_ROLE, new
StartNodeNonResizableEditPolicy());
}

I tried other Roles like GRAPHICAL_NODE_ROLE but this also
didn't work...

Thanks in advance.

Sometimes the LayoutEditPolicy adds that role to the child. Maybe it is
getting overwritten?

Hi,

I had problems determining which policy did what. I found that overloading
the method AbstractEditPart#understandsRequest(Request) with the following
cleared up a lot of my problems.

/*
* Just for debug
*/

public boolean understandsRequest(Request req) {
EditPolicyIterator iter = getEditPolicyIterator();
while (iter.hasNext()) {
EditPolicy ep = iter.next();
if (ep.understandsRequest(req)) {
System.out.println(className(this) + "/" +
className(ep) + " understands " +
className(req) + "/" + req.getType());
return true;
}
}
System.out.println(className(this) +
" has no policy for " +
className(req) + "/" +
req.getType());
return false;
}

/*
*
*/

public static String className(Object cls) {
String className = cls.getClass().getName();
return className.substring(className.lastIndexOf('.')+1);
}

Hope it helps.

Steve.
