Hello everybody,

I don't succeed in finding solution in following problem:

I know renderPixmap use initializeGL(), resizeGL(), and paintGL() in a new context.
So I do test with only one triangle textured. the list is creat with it's texture in initializeGL()
Result is good in window OpenGL but when I use renderPixmap, I got my triangle without image texture.

Here example code use in initializeGL() :
Qt Code: 
  1. void ViewerOGL::initializeGL(){
  2.     glClearColor(0.0f, 0.0f, 0.0f, 1.0f);   // Efface en noir
  3.     glClearDepth(1.0f);
  4.     glEnable(GL_DEPTH_TEST );              // Autorise le test de profondeur
  5.     glDepthFunc(GL_LEQUAL);
  6.     glFrontFace(GL_CCW );                   // Normale dans le sens horaire
  7.     glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
  8.     glShadeModel(GL_SMOOTH);               // Autorise anti-aliasing
  9.     glEnable(GL_CULL_FACE );                 // Face arriere cache
  10.     glEnable(GL_LIGHT0);                    // Active la 1ere lampe
  11.     glEnable(GL_COLOR_MATERIAL);            // Autorise les materiaux
  12.     glColorMaterial(GL_FRONT, GL_AMBIENT_AND_DIFFUSE);  // Autorise l'affichage
  13.  
  14.     glNewList(1, GL_COMPILE);
  15.         QImage img("C:\\test.png");
  16.         QImage tex;
  17.         tex = QGLWidget::convertToGLFormat(img);
  18.         GLuint nuId;
  19.         glGenTextures(1, &nuId);        // ID OpenGL sur la texture
  20.         glBindTexture(GL_TEXTURE_2D, nuId);
  21.         glTexImage2D(GL_TEXTURE_2D, 0, 4, tex.width(), tex.height(), 0, GL_RGBA,GL_UNSIGNED_BYTE, tex.bits());
  22.         glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
  23.         glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
  24.         glEnable(GL_TEXTURE_2D);
  25.             glBegin(GL_TRIANGLES);
  26.                 glTexCoord2f(0, 0);
  27.                 glNormal3f(0, 0, 1);
  28.                 glVertex3f(0, 0, 0);
  29.                 glTexCoord2f(1, 0);
  30.                 glNormal3f(0, 0, 1);
  31.                 glVertex3f(200, 0, 0);
  32.                 glTexCoord2f(0.5, 1);
  33.                 glNormal3f(0, 0, 1);
  34.                 glVertex3f(100, 200, 0);
  35.             glEnd();
  36.         glDisable(GL_TEXTURE_2D);
  37.     glEndList();
  38. }

Perhaps I forget an Enable, but which ?
Tanks for help
