Hello, so I have a custom WindowScrollWheelFcn callback I want to use, since I don't want the same callback for every axes handle I set. My question is this:

I set the custom scrollback function with:

set(h,'windowscrollWheelFcn', {@scrollfunc,gca});

but I want to send to the function (and return) handles data. How can I set this?

For example, with the code

function scrollfunc(object, eventdata, handles)

the handles function is set to a random value.
