[vtkusers] vtkBalloonWidget.. Help needed

[Ashley Sher]

Hi all,

I want use to vtkBalloonWidget to do a popup text. However, after creating a
project to test out this class, i realised that the vtk source i downloaded
had a few classes missing. So i download several header files,
vtkHoverWidget.h, vtkBalloonWidget.h, vtkBalloonRepresentation.h,
vtkAbstractWidget.h and vtkWidgetRepresentation.h. 

However, it still didnt work out. I think i missed out a few other files but
i'm not too sure what's them.

This is the error i got when i tried compiling:

TextInputDlg.obj : error LNK2019: unresolved external symbol
"__declspec(dllimport) public: void __thiscall
vtkBalloonWidget::AddBalloonText(class vtkProp *,char const *)"

Anyone has met with this problem before?
Thanks in advanced!!!
