show() in central main window

[ufo-vl]

Hello,

QDialog dlg( this );
dlg.show();

QDialog dlg( this );
dlg.show();

To copy to clipboard, switch view to plain text mode 

as result dialog window showed in random place,
can I show the dialog in main window central position?

now, for this task I use the following code:

QDialog dlg( this );
moveToCenter( &dlg );
 
void SMainWindow::moveToCenter( QWidget* child )
{
    if ( child->parentWidget( ) )
    {
        QSize szParent = child->parentWidget( )->size( );
        QPoint ptChild = QPoint( ( szParent.width( ) - child->size( ).width( ) ) / 2,
                ( szParent.height( ) - child->size( ).height( ) ) / 2 );
        child->move( ptChild );
    }
}

QDialog dlg( this );
moveToCenter( &dlg );

void SMainWindow::moveToCenter( QWidget* child )
{
    if ( child->parentWidget( ) )
    {
        QSize szParent = child->parentWidget( )->size( );
        QPoint ptChild = QPoint( ( szParent.width( ) - child->size( ).width( ) ) / 2,
                ( szParent.height( ) - child->size( ).height( ) ) / 2 );
        child->move( ptChild );
    }
}

To copy to clipboard, switch view to plain text mode 

There are other ways?

Yeah, if it works then use it.
There is no straightforward way to do that.

I thought dialogs with a parent got automatically centered.

A dialog is always a top-level widget, but if it has a parent, its default location is centered on top of the parent's top-level widget (if it is not top-level itself). It will also share the parent's taskbar entry.
