Note a major gotcha here. In python spaces and tabs are totally different, but they look just the same in an editor. So being indented one tab stop is not the same as being indented four spaces, even though they might look the same. And indentation level is very important in python. You will get a lot of errors if you mix tab indentation with space indentation. Your generated project follows the python standard of using four spaces for each indentation level. So you'll either have to hit the space bar four time every time you indent, or set up your editor to use the right number of spaces for tabs.</para>

Now you're ready to write some code. Of course just telling the glade file what signal to emit won't make the file actually save, because we haven't created the "save_file" function yet. The code for JottyWindow is stored in the file jotty. jotty is a special python file that is the entry point for your application. Other python files in your application have the ".py" suffix.</para>
