RemoveDrawObject() => Drawing is marks for deleting

[sidlercom80]

Hi, is there a way to determine if a drawing object was successfully deleted from the chart, or marked to be deleted in the next process?

private void RemoveDrawing(string tag)
{[INDENT]IsDrawingMarksToDelete = RemoveDrawObject(tag);

if (IsDrawingMarksToDelete)
{[/INDENT][INDENT=2]//...[/INDENT][INDENT]}
else
{[/INDENT][INDENT=2]//...[/INDENT][INDENT]}[/INDENT]
  }

Hello sidlercom80,

There are no specific events for pending deletion or successful deletion. There is an unsupported way to observe the chart objects changed event, there is a sample here:

Alternatively you would likely have to use the DrawObjects["Tag"] syntax and check if the returned object was null or not.
