Hi Nitin,
I am not 100% sure but did you try overloading ComputeSelection(const Handle(SelectMgr_Selection)& aSelection,const Standard_Integer aMode) function?
see AIS_Axis.cxx for example, I defined my own axis after deriving my class from AIS_Axis. I was unable to select the axis till I overloaded ComputeSelection function.

Hi Venu,
I tried to overload ComputeSelection method. In that StdSelect_BRepSelectionTool::Load(...) method needs TopoDS_Shape object, My Isession_Text class is derived from AIS_InteractiveObject not from TopoDS_Shape.
Can you pls suggest me how can i overload that method, Currently that method is blank in my code.

Hi Nitin,
I myself didn't implement selectable text though I am able to draw text. Pl take a look at this thread, not sure if you already have seen this. If you get it to work, please let me know.
