How can I execute a double-click callback without executing the single-click callback in my MATLAB GUI?

In order to set a double-click callback for my figure, I must set the SelectionType property to "open." However, when I double-click on my figure, MATLAB cycles the SelectionType through "normal" while I am clicking. This triggers my single-click callback. Thus both callbacks are executed instead of only my double-click callback.

You can use the following sample code to cause your application to execute only the double-click callback:

Associate this function with 'WindowButtonDownFcn' callback of the figure window.

function clickcallback(obj,evt)

persistent chk

if isempty(chk)

      chk = 1;

      pause(0.5); %Add a delay to distinguish single click from a double click

      if chk == 1

          fprintf(1,'\nI am doing a single-click.\n\n');

          chk = [];

      end

else

      chk = [];

      fprintf(1,'\nI am doing a double-click.\n\n');

end

I am disappointed that GUI's do not (apparently) support the double-click option in SelectionType. Why is there no disclaimer in the help files about this?

When will this bug be fixed?
