cannon.h

我在我的EP9315上写的两个QT程序

#ifndef CANNON_H
#define CANNON_H

#include <qwidget.h>

class QTimer;

class CannonField : public QWidget
{
  Q_OBJECT;
  public:
   CannonField( QWidget *parent=0, const char *name=0 );
   int angle() const {return ang;}
   QSizePolicy sizePolicy( ) const;

  public slots:
   void setAngle( int degrees );
   void paintSet( );
   void simulate( );
 
  private slots:
   void timerTest();  

  signals:
   void angleChanged( int );
  protected:
   void paintEvent( QPaintEvent * );

  private:
   int ang; 
   int timerCount;
   QTimer * autoShootTimer;
   
};

#endif
