How to use the bindTexture() function outside of the QGLWidget children?

8Observer8

Hello!

I have a class Scene:

@class Scene : public QGLWidget
{
// ...
void genTexture();
// ...
}

void Scene::genTexture()
{
triangleTextureID = bindTexture( QPixmap( QString( ":Textures/Stub.jpg" ) ), GL_TEXTURE_2D );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE );
}@

And I have a class Triangle:
@#ifndef TRIANGLE_H
#define TRIANGLE_H

// ...

class Triangle
{
// ...
}

#endif // TRIANGLE_H@

I want to move genTexture() to the class Triangle. How to use the bindTexture() function outside of the QGLWidget children?

Hi, not sure if it work have you tried to pass a "Scene" pointer to class Triangle??
@#ifndef TRIANGLE_H
#define TRIANGLE_H

#include "scene.h"
// ...

class Triangle
{
private:
Scene *m_scene;
void genTexture(){m_scene->genTexture;}

}@

if not work try also to add m_scene->context()->makeCurrent(); before m_scene->genTexture();

Thank you! I will try it. But I cannot see a texture. I don't know where is mistake. Please, run my simple example from this theme: http://qt-project.org/forums/viewthread/50872/

unfortunately i can't help you with this, i've just started learning OpenGL v3.3 and i have also some problems... However in previous version you should try glEnable(GL_TEXTURE_2D); if you are in compatibly context it should work, don't know if still exist in new version of openGL...
