Dear bosses, in a one of the main dialog, please click on the button control, pop-up a child dialogs, how can let the child dialog box is displayed in the main window is a central location?
The code is as follows:
Public mainDialog: public QDialog
{
Q_OBJECT
Public:
MainDialog (QDialog * parent=nullptr);
~ mainDialog ();

Private slots:
Void clickedOnSubDialog ();

Private:
QPushButton * m_button;
};

Public subDialog: public QDialog
{
Q_OBJECT
Public:
SubDialog (QDialog * parent=nullptr);
~ subDialog ();
}


MainDialog: : mainDialog (QDialog * parent) : QDialog (parent)
{
M_button=new QPushButton (QString (" next dialog "), this);
M_button - & gt; The resize (40, 30);
M_button - & gt; Move (this - & gt; Width () * 50/100, this - & gt; Height () * 40/100);
The connect (m_button, & amp; QPushButton: : clicked, this, & amp; MainDialog: : clickedOnSubDialog);
}

MainDialog: : ~ mainDialog ()
{

}

Void mainDialog: : clickedOnSubDialog ()
{
SubDialog DLG.
Int res=DLG. The exec ();
If (res!=QDialog: : Accepted)
{
return ;
}
}

SubDialog: : subDialog (QDialog * parent) : QDialog (parent)
{

}

SubDialog: : ~ subDialog ()
{

}
