setting needle size in qwtCompass

[Uwe]

Of course it has to look like this.

class myCompass: public QwtCompass
{
...
 
   virtual void drawNeedle( QPainter *painter, const QPoint &pos,
      int radius, double direction,
      QPalette::ColorGroup colorGroup) const
   {
      ...
   }
};

class myCompass: public QwtCompass
{
...

   virtual void drawNeedle( QPainter *painter, const QPoint &pos,
      int radius, double direction,
      QPalette::ColorGroup colorGroup) const
   {
      ...
   }
};

To copy to clipboard, switch view to plain text mode 

If this doesn't help start the debugger, set a breakpoint in QwtDial::drawNeedle and check if it is called from myCompass::drawNeedle.

Thank you Uwe.

It works now. I didn't type it properly: const QPoint instead of const QPoint &
