How to tell whether a draw object exists?

[cassb]

Let's say I do a DrawRay("ABC"...) on my chart so that I have a draw object created. Is it possible to query to see if that object exists on the chart? I just want a true/false property or method to tell me if it exists or not.

Thanks!

foreach(IDrawObject drawObject in DrawObjects)
{
  if (drawObject.DrawType == DrawType.Ray && drawObject.Tag == "ABC")
  {
       // Do something here
       break;
  }
}

Nice... thanks for exposing that object for us. :-)

Also, you used to be able to click on and manually move or delete draw objects that were created by a Draw...() function. Now you have to remove the whole indicator that drew it. Is this intended functionality?

Thanks again --

It is default functionality. In Initialize() set:

AllowRemovalOfDrawObjects = true;

The code provided by Ray seems to give access only to the user drawn drawobjects.

Is there a way to get access to the drawobjects drawn by indicators?

Is there a way to draw drawobjects programmatically in other panels than the price panel?

The DrawObjects colllection contains objects that are user drawn and drawn by the host indicator or strategy. There is no access to other objects drawn by other indicators etc...

To draw in the indicator panel set the the following property to false in Initialize()

DrawOnPricePanel = false;
