Functions

doneCurrent()

void QDirectFbGLContext::doneCurrent ( )

virtual

Reimplement in subclass to release current context.

Typically this is calling makeCurrent with 0 "surface"

Reimplemented from QPlatformGLContext.

Definition at line 79 of file qdirectfbglcontext.cpp.

{
    QPlatformGLContext::doneCurrent();
    m_dfbGlContext->Unlock(m_dfbGlContext);
}

getProcAddress()

void * QDirectFbGLContext::getProcAddress ( const QString &  procName )

virtual

Reimplement in subclass to native getProcAddr calls.

Note: its convenient to use qPrintable(const QString &str) to get the const char * pointer

Implements QPlatformGLContext.

Definition at line 85 of file qdirectfbglcontext.cpp.

{
    void *proc;
    DFBResult result = m_dfbGlContext->GetProcAddress(m_dfbGlContext,qPrintable(procName),&proc);
    if (result == DFB_OK)
        return proc;
    return 0;
}

makeCurrent()

void QDirectFbGLContext::makeCurrent ( )

virtual

Reimplement in subclass to do makeCurrent on native GL context.

Reimplemented from QPlatformGLContext.

Definition at line 73 of file qdirectfbglcontext.cpp.

{
    QPlatformGLContext::makeCurrent();
    m_dfbGlContext->Lock(m_dfbGlContext);
}

platformWindowFormat()

QPlatformWindowFormat QDirectFbGLContext::platformWindowFormat ( ) const

virtual

QWidget has the function qplatformWindowFormat().

That function is for the application programmer to request the format of the window and the context that he wants.

Reimplement this function in a subclass to indicate what format the glContext actually has.

Implements QPlatformGLContext.

Definition at line 100 of file qdirectfbglcontext.cpp.

{
    return m_windowFormat;
}

swapBuffers()

void QDirectFbGLContext::swapBuffers ( )

virtual

Reimplement in subclass to native swap buffers calls.

Implements QPlatformGLContext.

Definition at line 94 of file qdirectfbglcontext.cpp.

{
//    m_dfbGlContext->Unlock(m_dfbGlContext); //maybe not in doneCurrent()
    qDebug() << "Swap buffers";
}
