Hello Guys!

Simple question:
i have little problem with a feedback rectangle, shown on add request.
the rectangle paints, but when i have a zoom level != 1.00
the rectangle paints in the position and in the size as if zoom level was
1.00.

feedback = new RectangleFigure();
Rectangle r = getHostFigure().getBounds().getCopy().getExpanded(5,5);

feedback.setBounds(r);

addFeedback(feedback);

So how do i use translateToAbsolute / translateToRelative to fix this?

Regards, Ingo

Take a look at NonResizableEditPolicy -> showChangeBoundsFeedback.

I had a look a look at it.

what i want is rectangle with the same size (or a little bigger) of the
target figure resting over the target figure.

what i have:

feedback = getFeedbackRectangle();
Rectangle r = getHostFigure().getBounds().getCopy();
getHostFigure().translateToAbsolute(r);
feedback.setBounds(r);
addFeedback(feedback);

The size is ok now.
But not the position, when the editor is scrolled to the right.

And another (i admit, stupid, but simple) question :
why can

need to call:
feedback.translateToRelative(r);

Works fine now but only, when the feedback is added first,
then the rectangle gets transleted and the bounds are set.
The problem was, that at the time before the feedback is added,
it has no parent and the rectangle can

Yes, if the feedback is not on the feedback layer, then it will not work.
What happens is both the primary and feedback layer are shifted upwards.
So, when you translate from the original figure, you are shifting the point
one way. When yo utranslate back to the feedback, it un-shifts the point.
