[Sugar-devel] [PATCH sugar-toolkit] Cursor moves to beginning while trying to edit activity instance name #2608

[Sascha Silbe]

Excerpts from Aleksey Lim's message of Mon Feb 14 23:23:25 +0100 2011:

>      def __jobject_updated_cb(self, jobject):
> +        prev_pos = self.entry.props.cursor_position
>          self.entry.set_text(jobject['title'])
> +        self.entry.set_position(prev_pos)

The GTK documentation doesn't say anything about what the cursor position
will be after a set_text() call, so we need to take care of saving and
restoring the cursor position (i.e. your patch does the right thing).

But the documentation for set_position() says the position must not
exceed the number of characters currently in the widget, so we need some
bounds checking here (the title might have been shortened).
