Can add comment to an OBJECT?

 
When we stop mouse to a point of indicator line, a popup small window will display its name and current values.

Then it is possible add a comment to a Object, and get a same effect.
 
After you make the Object with ObjectCreate(), set its comment with ObjectSetText() (the second parameter). However, the object must not be OBJ_TEXT or OBJ_LABEL, cause in this case the comment will appear as text on screen (you want to create a tooltip). Though, I never tested this to see how actually works.
 
Thanks!
It it works and draw athose text one the screen directly, though I want to creat a tooltip.
