Arrow Deleted Event

Hi Stoyo,

I am having some issues on a chart that I have tracked to the ArrowDeleted event being fired when the Chart.ClearAll is called, as well as when a user deletes an arrow.

Is there anyway to limit when this event fires, or once it has fired, what the Action that caused it was?

Thanks in advance
JC

Hi JC,

Indeed, raising Deleted events in response to method calls is very inconsistent with how the rest of the events work. We'll probably fix this in a future release. Until then you will have to keep track of the event context yourself, for example:

Code
Select All
boolean cleanup = false;

void someMethod()
{
	cleanup = true;
	diagram.ClearAll();
	cleanup = false;
}

void diagram_LinkDeleted(...)
{
	if (!cleanup)
		...
}


I hope that helps,
Stoyan

That's pretty much how I've handled it, just wondered if there was anything inbuilt.

Thanks again
JC
