Hi,

I have the following code which creates a core dump when I run the program . 
This compiles fine.

Can somebody help me with this. I am trying to modify the "Punidraw" program to 
put some new GraphicComp in it.

Here is the relevant lines from code....

class PictComp : public GraphicComp {
 ..........................
 .......................
 };

 ........................
 class MyComp : public GraphicComps {
 public:
       MyComp() {};
       }


.................................
...............................

Picture* picture = new Picture();
GraphicComp* Newcomp = new MyComp();
GraphicView* view = (GraphicView*) Newcomp->Create(COMPONENT_VIEW);
Newcomp->Attach(view);

Label* MyLabel = new Label ("New Comp");
MyLabel->SetTransformer(new Transformer(1, 0, 0, 1, 18, 1.5));
picture->Append(MyLabel);
PictComp* pcomp = new PictComp(picture);
Newcomp->Append(pcomp);

ControlInfo* _VPanelControl_924_info = new ControlInfo(Newcomp, "r", "r
  ");
Tool* _VPanelControl_924_tool = new GraphicCompTool(_VPanelControl_924_info, (GraphicComp*) Newcomp->Copy());
VPanelControl* _VPanelControl_924 = new VPanelControl("_instance_521", _VPanelControl_924_info, _curCtrl_0);
GetKeyMap()->Register(_VPanelControl_924);

.........................



 Am I totally in the wrong track? Is there a better way to do this?

 Thank you
 Ranjana
