This is exactly the way to learn and have fun. It might be a good idea to also keep in mind that you are learning two things at the same time: Python and GTK. <blockquote cite="mid:1429438239.2644.6.camel@vey-waldorf" type="cite"> <pre wrap=""> I have tried (in various permutations) to make use of code borrowed from Terminal, Pippy, Develop, Browse, ReadETexts, and Write. I get stuck just writing a "vanilla" function definition for `__copy_cb` as in: `edit_toolbar.copy.connect('clicked', self.__copy_cb)` . What am I missing? This "fresh start" approach seems to demonstrate a "most naive" form of my error. I take Help-19 as my base (working with sugar-runner, on Fedora 20). I edit helpactivity.py adding 5 segments [1] of code I borrowed from Terminal and Pippy.</pre> </blockquote> The third segment has a commented line in [2] (line 192), but not in [1]. This is the line where the object text_buffer is created in the original code. Since in line 194, the code tries to access a method of this object, it will fail because at this point in the code, text_buffer is None. This will stop execution of the code and thus the hotkey does nothing. <blockquote cite="mid:1429438239.2644.6.camel@vey-waldorf" type="cite"> <pre wrap=""> The resulting modified helpactivity.py is [2]. For this example, no further debugging or "improvements". The Activity runs, and looks ok, the copy button works to the extent that the selected text can be pasted with the centre mouse button, but not with a Sugar Paste button (or Ctrl+Shift+V). When I press the "new" Copy button, no clipping shows in the Frame. The Debug error is: File "~/Activities/SugarTutorial.activity/helpactivity.py", line 194, in __copy_cb text_buffer.copy_clipboard(clipboard) AttributeError: 'NoneType' object has no attribute 'copy_clipboard'</pre> </blockquote> You need to find out what text_buffer is supposed to be. My guess is that you need to ask your Webkit.WebView object (instantiated as <meta http-equiv="content-type" content="text/html; charset=windows-1252"> self._web_view in your code), what text is selected (and put that into text_buffer). It is always good to have docs at hand, and also Q&A websites are good for these kinds of details. Here's a relevant question answered, and it seems Webkit is a little quirky: <a class="moz-txt-link-freetext" href="http://stackoverflow.com/questions/14823892/whats-the-method-to-get-the-webkit-webviews-currently-selected-text">http://stackoverflow.com/questions/14823892/whats-the-method-to-get-the-webkit-webviews-currently-selected-text</a> <meta http-equiv="content-type" content="text/html; charset=windows-1252"> <blockquote cite="mid:1429438239.2644.6.camel@vey-waldorf" type="cite"> <pre wrap=""> I guess I am missing something very obvious, grateful if anyone could throw me a clue.
