How to use opengl on qt ?

shadowfox

well i can now draw a picture there. but it can't move.
for example i use this code in paintGL
@
void visualazition::paintGL(){

glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glLoadIdentity();

for (int i=0;i<=10;i++){

glTranslatef( -1.5,  0.0, -6.0 );
glTranslatef( rTri,  0.0, -2.0 );

glBegin( GL_TRIANGLES );
  glColor3f( 1.0, 0.0, 0.0 );
  glVertex3f(  0.0,  1.0,  0.0 );
  glColor3f( 0.0, 1.0, 0.0 );
  glVertex3f( -1.0, -1.0,  0.0 );
  glColor3f( 0.0, 0.0, 1.0 );
  glVertex3f(  1.0, -1.0,  0.0 );
glEnd();

glLoadIdentity();
glTranslatef(  1.5,  0.0, -6.0 );
glRotatef( rQuad,  1.0,  0.0,  0.0 );

glColor3f( 0.5, 0.5, 1.0 );
glBegin( GL_QUADS );
  glVertex3f( -1.0,  1.0,  0.0 );
  glVertex3f(  1.0,  1.0,  0.0 );
  glVertex3f(  1.0, -1.0,  0.0 );
  glVertex3f( -1.0, -1.0,  0.0 );
glEnd();
QTime dieTime = QTime::currentTime().addMSecs(1000);
while( QTime::currentTime() < dieTime )
    QCoreApplication::processEvents(QEventLoop::AllEvents, 1000);
//glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
rTri += 0.2;
rQuad -= 0.15;

}@

but it only show the final picture. i want to see tirangles moving on screen.

Maybe using Signals and Slots for timing more preferred?
