Error: 'QGLBuffer::IndexBuffer' is not a type

Karunesh

While creating a structure to hold information regarding an object, I am getting an unexpected error, something like

@C:\K_QT\Learning\Minimal_Qt_OpenGL\minimal_example-build-desktop..\Qtopengl_minimal_example\glwindow.h:28: error: 'QGLBuffer::IndexBuffer' is not a type@

The structure (in the file) looks like:

@
#ifndef GLWINDOW_H
#define GLWINDOW_H

#include <QGLWidget>
#include <QTimer>
#include <QtOpenGL/qglshaderprogram.h>
#include <QtOpenGL>

class GLWindow : public QGLWidget
{
Q_OBJECT
public:
GLWindow(QWidget *parent = 0);
~GLWindow();

void resizeGL(int width, int height);
void initializeGL();
void paintGL();

/////////////////////////////////////////////////////////////////////////////////////////////
struct Drawable {
    QGLBuffer  vertexBuffer;
    QGLBuffer  indexBuffer(QGLBuffer::IndexBuffer); ///////////////// PROBLEM HERE
    int     faceCount;
    GLfloat transform[16];
};
/////////////////////////////////////////////////////////////////////////////////////////////

struct Drawables
{
    Drawable Truck;
    Drawable Cub01;
    Drawable Cube;
};
Drawable m_drawables;

QMatrix4x4 truck;
QMatrix4x4 cub01;
QMatrix4x4 cube;

void CreateDrawable(GLfloat* vertices,GLfloat* tex,GLfloat* normals,GLushort* face,int facecount,QMatrix4x4 &matrix);

protected:
QGLShaderProgram m_sampleProgram;
};

#endif // GLWINDOW_H
@

Initializing the vertexBuffer with 'QGLBuffer::VertexBuffer' leads to the same error, with both qglbuffer objects.

Am I doing something wrong? (I am kind of clueless.)

p.s. I am writing QT += opengl in my .pro file, and the project (though small) was compiling and running correctly until I decided to use buffers.

Try adding:

@
#include <QGLBuffer>
@

at the top of your file.
