QGraphicsView and QWebView size question

[MarkoSan]

Hi to all!

I have following question regarding my problem. I've made QMainWindow and inside it I have one QDockWindow. Inside QDockWindow there is a tab widget with two tabs, one for QGraphicsView and other for QWebView. Now, QMainWindow is always maximized to full screen. I would also to maximize this docking window so it cannot be resized. Then, the sizes of QGraphicsView and QWebView also must be maximized. How do I achieve that. Here is the code of header:
#ifndef CCENTRALWIDGET_H
#define CCENTRALWIDGET_H

#include <QtGui/QDockWidget>
#include <QtGui/QTabWidget>
#include <QtGui/QGraphicsView>
#include <QtWebKit/QWebView>
#include <QtGui/QWidget>
#include <QtGui/QSizePolicy>
#include <QtCore/QString>

//#include "ui_ccentralwidget.h"

class CCentralWidget : public QDockWidget
{
Q_OBJECT

public:
CCentralWidget(/*const QString& strTitle,*/
QWidget *pParent=0,
Qt::WindowFlags flags=0);
~CCentralWidget();

inline QTabWidget* optionsWidget() const
{ return m_pOptionsWidget; };
inline QGraphicsView* merchandizeView() const
{ return m_pMerchandizeView; };
inline QWebView* webpageView() const
{ return m_pWebPageView; };
inline QWidget* merchandizeViewContainer() const
{ return m_pMerchandizeViewContainer; };
inline QWidget* webpageContainer() const
{ return m_pWebPageContainer; };

private:
void createOptionsWidget(); // method for creation options tab
void createMerchnadizeView(); // method for creating merchandize view
void createWebPageView(); // method for creating web page view

/*

#endif // CCENTRALWIDGET_HAnd here is implementation file:

//ui.setupUi(this);

createWebPageView(); // creates web page view

optionsWidget()->addTab(merchandizeViewContainer(),
tr("Room service"));
optionsWidget()->addTab(webpageContainer(),
tr("City sightseeings"));
}

CCentralWidget::~CCentralWidget()

}

void CCentralWidget::createMerchnadizeView()
{
m_pMerchandizeViewContainer=new QWidget(optionsWidget()); // creates new widget
Q_CHECK_PTR(m_pMerchandizeViewContainer); // checks creation
/*

}That commented geometry statements do not work :crying:. Please help!
