Merge lp:~ryanriffle/writer/instant_style_apply into lp:writer

[Ryan Riffle]

I made clicking bold, italic, and underline apply the style instead of having to select the text first. Also in TextToolbar I added focus_on_click = false to the other buttons aside from bold.

I had to change the way TextEditor.cursor_moved is called, because the notify caused cursor_moved_callback to be called before text_insert_callback was called, therefore resetting the styles. Also added a mouse click event because Gtk.TextView.move_cursor signal does not emit if the user clicks somewhere in the text.

[Ryan Riffle (ryanriffle)]

I am not sure what the design should be. Whether you want to use a dictionary for the added members or a new TextStyle class. Just let me know and I can change it.

[Ryan Riffle (ryanriffle)]

Is this going to be reviewed?

[Tuur Dutoit (tuur-dutoit-f)]

Yes, of course. I'm sorry, I've been lazy the last few days (after exams...). Tomorrow I'll get some work done.

[Tuur Dutoit (tuur-dutoit-f)]

That's very good, I'm merging it in.
