Remove resize handlers [message #1313480]

Hi,

I have a diagram with objects that I don't want to resize. I created a resize feature that always returns false. However, when I select an object on the editor, the resize handlers are still there, and is even possible to move them (without resizing the object...). Can I hide those handlers?

Thanks!

I don't know exactly how you do this but I created Resize Feature as follow and it is working as expected:

public class ResizeShapeForbiddenFeature extends DefaultResizeShapeFeature {

	public ResizeShapeForbiddenFeature(IFeatureProvider fp) {
		super(fp);
	}

	@Override
	public boolean canResizeShape(IResizeShapeContext context) {
		return false;
	}
}

If you want them to be unable to get moved, you have to extend the

AbstractMoveShapeFeature

for example.

Thanks Marek Jagielski. Your class is similar to mine, so the problem wasn't there, but your answer sent me on the right direction.

Actually, I had an error in the FeatureProvider, I forgot to change the line that checked the type of object (it was still checking if the object was of type EClass, like in the tutorial...)

@ Soeren M: i wanted to disable the capacity to move the handlers, not the object, but thanks anyway Wink
