how to wait for mouse press without figure or gui?

Hi all,

I need to capture a small rectangle region of screen that defined by the user.

I need a way to get from the user two pointer location.

How do I do that without figure or gui ?

should be something like:

% wait for mouse press and released 
p1 = get(0, 'PointerLocation');

% wait for mouse press

while mouse not released
   p2 = get(0, 'PointerLocation');
   %draw rectangle window on screen
   pause(0.5)
end

capture window.

I'm open for any suggestions even java.awt.Robot/java.awt.MouseInfo

Thx

Zohar - is the screen a MATLAB figure or is it outside of the MATLAB environment?

Hi Geoff,

I need the mouse location outside matlab environment.
