Hi...

I have written a small application using Q3Canvas... i have got a Big List of errors.. i culdnt understand why it was as i have all the header files included and present.
i am pasting the code of the three files... i culdnt understand the error....

CanvasView.cpp
Qt Code: 
  1. #include "canvassample.h"
  2. #include <QtGui/QPixmap>
  3.  
  4. CanvasSample::CanvasSample(Q3Canvas *canvas) : Q3CanvasView(canvas)
  5. {
  6.   canvas = new Q3Canvas(100,100);
  7.   canvas->setBackgroundColor( Qt::black );
  8.   canvas->setBackgroundPixmap( QPixmap( "stars.png" ) );
  9. }
  10. CanvasSample::~CanvasSample()
