Help Using Help Reference Back 70 select (Mac OS) On Mac OS, the optional second argument is a callback function. This function takes one argument, which is a File object. When the dialog is set up, it calls this callback function for each file that is about to be displayed. If the function returns anything else than true, the file is not displayed. This is true only for the openDialog() method; the saveDialog() method ignores this callback method. Returns File object, or null if the user cancels the dialog.
