Ownership of drawing objects

[Gianpiero]

Hello!

My indicator draws some text objects on the price panel. The problem is that I'd like to delete some of them without also removing the indicator that created them. Is it possible to dissociate a drawing object from the indicator or to assign it to a different owner?

Hello Gianpiero,

To remove an object your indicator can do that in its logic. You would use the RemoveDrawObject("tag") method.

Thank you, that's interesting regarding a different approach to my problem. However, that's not exactly what I was looking for. I didn't explain myself clearly. What I want to do is to delete manually some text drawn algorithmically without also deleting the indicator from the chart

Hello Gianpiero,

If a script draws an object that script owns the object through its lifecycle. To remove the object you would need to program into that indicator a way for it to delete it. That would be based on conditions or in a more advanced case you could add a custom button to the chart which calls RemoveDrawObject in the indiators code.

Ok, I understand, but how would I add such a button? Moreover, is it possible to assign a different owner instead of 'this'?

Hello Gianpiero,

The owner would need to be the script which is managing it, that can be the indicator that draws it. There is not a way remove the owner so you can manually delete objects. You would need to make logic in that script to manage the objects in the way that you wanted.
