Some artifacts when clicking on diagram

Hi all,

I set diagram behavior as "do nothing":
diagram.setBehavior(MindFusion.Diagramming.Behavior.DoNothing);

But I still have node selected (ports became visible) when I click on it. Also I have some strange  artifacts (see example attached), it looks like some selected nodes a duplicated with an offset. Is it possible to turn it off?

Hi Anna,

Try this -

Code
Select All
var originalOnClick = Diagram.prototype.onClick;
Diagram.prototype.onClick = function (position, button)
{
	if (this.getBehavior() == Behavior.DoNothing)
	{
		var clickedItem = this.getItemAt(position, true);
		this.raiseClicked(clickedItem, position, button);
	}
	else
	{
		originalOnClick.apply(this, [position, button]);
	}
};

This could be the shadow effect, or otherwise the control might not have repainted correctly after some modification of yours (e.g. if you assign to bounds field directly instead of calling setBounds, or a property setter of ours omits invalidating); try calling diagram.invalidate() to do a full repaint.

Regards,
Slavcho
