Functions

doneCurrent()

void QWaylandGLContext::doneCurrent ( )

virtual

Reimplement in subclass to release current context.

Typically this is calling makeCurrent with 0 "surface"

Reimplemented from QPlatformGLContext.

Definition at line 100 of file qwaylandglcontext.cpp.

Referenced by setEglSurface().

{
    QPlatformGLContext::doneCurrent();
    eglMakeCurrent(mEglDisplay, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT);
}

eglConfig()

{
    return mConfig;
}

getProcAddress()

void * QWaylandGLContext::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 111 of file qwaylandglcontext.cpp.

{
    return (void *) eglGetProcAddress(string.toLatin1().data());
}

makeCurrent()

void QWaylandGLContext::makeCurrent ( )

virtual

Reimplement in subclass to do makeCurrent on native GL context.

Reimplemented from QPlatformGLContext.

Definition at line 91 of file qwaylandglcontext.cpp.

Referenced by setEglSurface().

{
    QPlatformGLContext::makeCurrent();
    if (mSurface == EGL_NO_SURFACE) {
        qWarning("makeCurrent with EGL_NO_SURFACE");
    }
    eglMakeCurrent(mEglDisplay, mSurface, mSurface, mContext);
}

platformWindowFormat()

QPlatformWindowFormat QWaylandGLContext::platformWindowFormat ( ) const

inlinevirtual

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 63 of file qwaylandglcontext.h.

{ return mFormat; }

setEglSurface()

void QWaylandGLContext::setEglSurface

(

EGLSurface

    if (QPlatformGLContext::currentContext() == this) {

    mSurface = surface;
    if (wasCurrent) {
        makeCurrent();
    }
}

swapBuffers()

void QWaylandGLContext::swapBuffers ( )

virtual

Reimplement in subclass to native swap buffers calls.

Implements QPlatformGLContext.
