pygame display position

Hi!

I am working on some zoomable objects, that react to the screen getting 
resized.

Is there a way to
a) get the current desktopsize
b) get the window-position on the desktop
c) react to the 'close' event of that window (little cross in the upper 
right corner has to actually work) and have a screen that is able to resize 
(and have some code fired when it does)?

With kind regards, Roelie
