Here's some code:

MayaFourView.h
@#pragma once
#include <QtGui>
#include "MayaSimFrame.h"

class QSplitter;
class MayaSimFrame;

class MayaFourView :
public QWidget
{
Q_OBJECT
public:
MayaFourView(QWidget *parent = 0);
~MayaFourView(void);
private:
MayaSimFrame *openGLSceneViewLeft;
MayaSimFrame *openGLSceneViewTop;
MayaSimFrame *openGLSceneViewFront;
MayaSimFrame *openGLSceneViewPerspective;
QSplitter *newSplitter1;
QSplitter *newSplitter2;
void loadStyleSheet(const QString &sheetName);

};

MayaFourView.cpp
@#include "MayaFourView.h"

MayaFourView::MayaFourView(QWidget *parent)
: QWidget(parent)
{

newSplitter1 = new QSplitter;
newSplitter2 = new QSplitter;

/newSplitter1->setOpaqueResize(false);/

newSplitter1->setAttribute(Qt::WA_PaintOnScreen);

/newSplitter2->setOpaqueResize(false);/

newSplitter2->setAttribute(Qt::WA_PaintOnScreen);

QSplitter *vSplitter = new QSplitter;
vSplitter->setOrientation(Qt::Vertical);
vSplitter->addWidget(newSplitter1);
vSplitter->addWidget(newSplitter2);
setAttribute(Qt::WA_PaintOnScreen);

/vSplitter->setOpaqueResize(false);/

vSplitter->setAttribute(Qt::WA_PaintOnScreen);
setAutoFillBackground(false);
openGLSceneViewTop = new MayaSimFrame("Top left view");
newSplitter1->addWidget(openGLSceneViewTop);

openGLSceneViewPerspective=new MayaSimFrame("Top right view");
newSplitter1->addWidget(openGLSceneViewPerspective);

openGLSceneViewLeft=new MayaSimFrame("Bottom left view");
newSplitter2->addWidget(openGLSceneViewLeft);

openGLSceneViewFront=new MayaSimFrame("Bottom right view");
newSplitter2->addWidget(openGLSceneViewFront);

QHBoxLayout *layout = new QHBoxLayout;
layout->addWidget(vSplitter);

layout->setSpacing(0);
layout->setMargin(0);
setLayout(layout);
setWindowTitle(tr("QtGLFrame"));
resize(800,600);
}

MayaFourView::~MayaFourView(void)
{
}

void MayaFourView::loadStyleSheet(const QString &sheetName)
{
QFile file(":/theme/"+ sheetName.toLower()+".qss");
file.open(QFile::ReadOnly);

QString styleSheet = QLatin1String(file.readAll());
qApp->setStyleSheet(styleSheet);
