Hi,
	How can i set an QHBoxLayout as the central item of an QDialog ?

	Often in QMainWindow , i'd morph an QHBoxLayout into a QWidget , and
use setCentralWidget function. However it doesn't work this time.

	Sample Code:
		
		I've got a UI file ,  has an memeber called mainLayout which is a
QHBoxLayout.


MasterWindow::MasterWindow(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::MasterWindow)
{
    ui->setupUi(this);
    theme *th = new theme();
    ui->mainLayout->addWidget(th);
}


How can i make ui->mainLayout centrally ?

Appreciate any of your help ;-)

Thanks in advance !
