问题 I have files of a format that has no declared UTI, so Launch Services has assigned to it a dynamic UTI ( dyn.ah62d4rv4ge81g23wsmw1a5dbte ). I have no control over the UTI of these documents. It also happens that I would like to develop a Quick Look generator for that format, and that Quick Look generators only rely on the document UTI, and will ignore any other kind of document identification present in their property list (such as the creator code and the extension). Is it safe for me to use

问题 Why can't I get the python tkinter canvas to respond to the vertical and horizontal swiping/scrolling of Apple's Magic Mouse?
