Collect output of gui as a regular function

Dear all, I recently asked a question on how to share handles between two different GUIs. This is a slightly different question.

Is there any way to collect the output of a gui once the gui is closed a regular function? Something such as:

function b=myNONguiFunction %this is my main function

a=myGui; %here's my GUI is started, once it is closed it should return a as a result

b=a+1 %here's my main function's task

I was wondering if there's any way to achieve this in a simple way without the need of sharing handles.

Thanks!

I found this: http://blogs.mathworks.com/videos/2010/02/12/advanced-getting-an-output-from-a-guide-gui/

Looks like a good solution wven though I don't undestand what he does with the close request function since that way you have to clic twice to get your window to close...

If anyone has a better idea, please share.

Thanks!
