I am using the get function to retrieve the mouse position like this:
get(0,'PointerLocation');
I also need to detect when a mouse button has been clicked. I've tried searching everywhere I know to search for this and cannot find how to do it. I also can't really find everything the get function can do (such as PointerLocation or ScreenSize, etc).
I'm using the java robot in other places in my code to move the mouse and get screen pixel colors. Is there any java functionality that will detect mouse clicks? Is there good documentation on what other java functionality there is for matlab and how to use it (syntax)?
Thanks in advance

Brandon, This can be achieved using 'WindowButtonDownFcn' property of the figure object.
Here is a demo code for the same:
function demo()
figure('WindowButtonDownFcn',@callBack)
function callBack(hObject,~)
mousePos=get(hObject,'CurrentPoint');
disp(['You clicked X:',num2str(mousePos(1)),', Y:',num2str(mousePos(2))]);
Hope this helps!

That works nicely, but I need this to work in another window outside of Matlab. Can this work like that with a modification or is there any other way to do it?

what exactly do you mean by "another window outside of Matlab"?
