G'day All,

I have a set of 10 or so QWidgets that are used in application main window code like:
Qt Code: 
  1. QWidget * widget = new ThingoWidget;
  2. QMdiSubWindow * sw = m_ui->mdiArea->addSubWindow(widget);
  3. sw->show();
To copy to clipboard, switch view to plain text mode 
to create MDI sub windows (each a different view of the same document) as needed. I'd like each type of sub-window to remember its position and size and restore that the next time it is opened.

I can capture the location on close by overriding the QWidget::closeEvent() in ThingoWidget to store the pos() and size() of the widget's parent QMdiSubWindow. I cannot use the ThingoWidget constructor to restore these values because the parent QMdiSubWindow does not exist until after the widget is constructed. Is there somewhere in the widget code I can restore the parent window geometry (slot or handler method), will it have to be done in the main window code above, or should I rewrite my widgets as QMdiSubWindow derivatives?

Any thoughts appreciated
