Can I delete an object in event handler |
|
|
Hi everybody,
I'm trying to write an event handler to edit block attributes while user
double-clicked specific type of block.
Within the double-click event handler, I access the block by using the
Pickfirst selection set, then check the object type that match what I want.
For example a Block named "CAP SCREW" have 4 attributes:
NO , REMARK, LENGTH, BORE_DEPTH.
But because there may be some block with old definition which just have
the 1st 2 attributes. In this case I need to redefine the block and then
insert
a newly defined block at the same position. Finally the old block needs to
be deleted.
**** NOW I HAVE THE PROBLEM TO DELETE THE OLD BLOCK
WITHIN THE EVENT HANDLER ****
Can anyone teach me how to solve the problem.
Or even don't have to delete the old block, may be there is a way to
redefine
my existing block but I don't know.

I'm not sure you can do this. You can't delete an object that fired an
event. Have you considered just updating all the blocks?
Hope that helps,
