If you're using QMainWindow see QMainWindow::saveState() and 
QMainWindow::restoreState().

Also QWidget::saveGeometry(), and QWidget::restoreGeometry().

For application specific stuff like file path and font size you will need to 
save and restore things individually, but QSettings is pretty easy to use.
