vlr-object-reactor (element modification)

[jerzy.bajor]

Hello

I want to get entity an element on which I made a double-click. I suspect that I have to use the rector 'VLR-Object-Reactor' in combination with ': VLR-MODIFIED'. I tried something below, but I don't mean. Can someone help me how to do it. My English is not very good to seek efficiently in help, hence this request

(defun Reacto ()
  (if (= *EndReacto* nil)
    (vlr-object-reactor nil '((:vlr-modified . GetHandent)))
    )
  )

(Reacto)

(defun GetHandent (A)
  (setq dadas 1)
  )

Perhaps its just the language barrier but this sounds like you could just do (entsel).

As I wrote, it is to start after a double click, not by indicating the element.

Just redefine the double click action to use (entsel) or whatever you need

And how to define that after a double click on this element that I want (e.g. a red line with a thickness of 50) is to start my code?

[annoisscary]

It kind of sounds like you just want to start a lisp by double clicking on an object. Which you could do by changing the double click action to call the function. You would just write "^C^Cyour-command" in the macro line

We are heading in the right direction.
I use the AutoCAD overlay, which has its own elements.
I have already done something that after the command I check what element it was edited. And if it was part of this overlay, then it makes my code.
The problem is that each time I search the whole drawing in search of these 'foreign' elements and I am looking for changes in them. With a small amount it goes somehow, but with a large amount it is already with trouble with time.
That is why I want to catch at the very beginning, what an element is, catch it before the change and compare after the change.
