Same Width of Qt's Bottom Drawer and its parent QMainWindow

[santosh.kumar]

Hi

I am using Qt 4.6.4 on MacOSX.

QDockWidget *m_pDockWidget = new QDockWidget(this,Qt:rawer);
MyWdgt *m_pMyWdgt = new MyWdgt(this);

m_pDockWidget->setFixedWidth(750);
m_pDockWidget->setFixedHeight(220);

m_pDockWidget->setWidget(m_pMyWdgt);
this->addDockWidget(Qt::BottomDockWidgetArea,m_pDockWid get);

It Start showing Drawer After Bottom of QMainWindow. But Drawer's width is not same as QMainWindow's width.

I want to set Same Width as QMainWindow. But it always some width less than QMainWindow.

I have attached sample Screen. Kindly tell me the solution for this.

Thanks
Santosh
