Hi BE,

There is no "reset()" method on QMainWindow.

However, there might be a way to do it anyway. I haven't tried this, but 
it's what I would do for the first attempt if I had to implement it.

On startup store the state of the window at the point where you to 
restore it to. You use "saveState()" and "saveGeometry()" for this. When 
you want to reset it, call "restoreState()" and "restoreGeometry()".

You can see examples of this in the QMainWindow documentation. The 
examples store the values in QSettings because this is almost always 
used to restore the window the next time the user starts the 
applicaiton. But it should be simple for you to adjust this to your problem.

I hope this helps.
