Hi everyone, well my problems is that I tried to do a basic aplication where I could open a OGLWidget and I says that I dont haves de #include<OGLWidget> in the defeaul folder.

So, What library shoud I open if I want to do this? (I'm using Qt4.4.3 Opensource).

And Here is my code:
jose.h

Qt Code: 
  1. #ifndef JOSE_H
  2. #define JOSE_H
  3.  
  4. #include <QApplication>
  5. #include <QDialog>
  6. #include <QPushButton>
  7. #include <QWidget>
  8. #include <QFont>
  9. #include <OGLWidged>  //-----Here's the "missing file"
  10.  
  11. class josewidget : public QWidget
  12. {
  13.  public:
  14.  josewidget (QWidget *parent = 0);
  15.  
  16. //public slots:
  17.   //      void repaint();
  18.  
  19. protected:
  20.            void paintEvent(QPaintEvent *event);
  21.            void repaint();
  22. };
  23.  
  24. #endif

jose.cpp
Qt Code: 
  1. #include "jose.h"
  2. #include <QTime>
  3. #include <QTimer>
  4. #include <QPainter>
  5. #include <QPaintEvent>
  6.  //#include <QGLWidget>
  7.  
  8. josewidget::josewidget(QWidget *parent)
  9.                                : QWidget(parent)
  10. {
  11.  //OGLwidget = new OGLWidget;
  12.  
  13.  setFixedSize(400,200);
  14.  setAutoFillBackground(false);
  15.  
  16.  QPushButton *ok = new QPushButton(tr("Ok"),this);
  17.  ok->setGeometry (60,40,75,30);
  18.  ok->setFont(QFont("Times",18, QFont::Bold));
  19.  
  20.  QPushButton *quit = new QPushButton(tr("Salir"),this);
  21.  quit->setGeometry (150,40,165,30);
  22.   quit->setFont(QFont("Times",18, QFont::Bold));
  23.  
  24.  connect(quit,SIGNAL(clicked()),qApp,SLOT(quit()));
  25.  connect(ok,SIGNAL(clicked()),qApp,SLOT(Event));
  26.  
  27.  }
  28.  
  29.  
  30.  
  31. void josewidget::paintEvent(QPaintEvent *event)
  32. {   
  33.  
  34.     unsigned long int i;
  35.     QTime time;
  36.     time.currentTime();
  37.     qsrand ((unsigned int)time.second());
  38.  
  39.     QPainter painter(this);
  40.     painter.setPen(QPen(Qt::black, 1, Qt::SolidLine, Qt::RoundCap));
  41.     painter.setRenderHint(QPainter::Antialiasing, true);
  42.     for(i=0;i<=100000;i++){
  43.         painter.drawPoint(qrand()%400, qrand()%300);
  44.     }
  45. }
