Hi

When deleting a box, any arrows between this box and other boxes are also deleted. If the "ArrowDeleted" event is handled I have noticed that one can still obtain information (Tag, UserString etc.) from the box which was deleted.
My question is thus, When is it no longer possible to obtain information about a deleted box and what can be done to it besides obtaining info?


Best regards,
Magnus

Hi Stoyan

If I understand you correctly, using the commands:

arrow.GetOriginBox();
arrow.GetDestinationBox();

in the "ArrowDeleted" event is a very bad idea! Am I right?

How about when deleting a box. Is it safe to use the "box" item in the "BoxDeleted" event?


Best regards,

Hi Stoyan

Thank you!
So the commands:

arrows.GetOriginBox();
arrows.GetDestinationBox();

are OK as long as they are used within the "ArrowDeleted" event?

Also:
I have two boxes connected by an arrow. When one box is deleted the other one should be deleted as well. First I put some code in the "BoxDeleted" event to do this using the arrow connecting the boxes. This did not work since when deleting a box, the code in the "ArrowDeleted" started executing directly so that when the code in "BoxDeleted" should execute the arrow was  not available!
Second I tried putting some code in the "RequestDeleteBox" event but this did not work either. This code included a for-loop but this only executed once and control never returned to this loop.

Any ideas?

Best regards,
Magnus
