MOUSE DOUBLE CLICK PROBLEM

The script Im using has an option to accept the double click as the answer and move to next question. However, matlab does not accept my double click (IM USING TRACKPAD NOT A MOUSE). I am a mac user with OS catalina 10.15. Has anyone faced the same issue, any help would be appreciated!

Vertika - can you show us the code that you are using to accept a double-click? This example (from https://www.mathworks.com/matlabcentral/answers/96424-how-can-i-execute-a-double-click-callback-without-executing-the-single-click-callback-in-my-matlab-g) works as expected on my Mac via a double-click of the trackpad

function example
close all
set(gcf,'WindowbuttonDownFcn',@clickcallback)
function clickcallback(obj,evt)
switch get(obj,'SelectionType')
    case 'normal'
    case 'open'
        disp('double click')
end

The other, "accepted", answer on that link might be better suited to handle both a single-click and a double-click event, that might be what the OP looked for (and if it is it is the solution to my problem!)...

Once I wrote an image-processing tool where I wanted to use all 4 mouse-button events - but it seemed as if the double-click event always triggered the a single-click event first, and then a double-click event. For my case that was possible to deal with (the response to the single-click did not noticeably change the response to the double-click). This was a couple of years ago, so this might have changed. You could try to write the most basic event-handling function and check what it does to the different events - something like just echo a number for each event. That might tell you how this is handled on your system.
