Quick question, how can i pass some other variables that i want in mousePos

The data variable is defined in the main function but i want to use it here too.

set(frt, 'WindowButtonDownFcn', {@mousePos, data} )
function mousePos(hObject, ~, data)
Note: this will use the value of "data" as of the time the callback is created, and will not reflect any updates to "data" that are made after that.

Another thing, i was trying to save each rectangle i created so later on i can have acces to the position of the one i want. The code below is not working though.
for i = 1:compnum
id = [num2str(i)]; = imrect(gca, compdata(i,:));

To Raldi,
Hi~ Have you found the way to update the value of "data" ?
I encountered the same problem and don't know how to update it.
Thanks for your help in advance.
