Thanks Carl. I also discovered that the actual text gets set in
Editor::set_verbose_canvas_cursor(). I added an extra line to
show_verbose_canvas_cursor() so that it now looks like this:-
/* My line */ Glib::ustring str =
verbose_cursor_visible = true;
The extra line proved that the text was still valid at the time it's
about get shown - but all I actually see is a long string of zeros (or maybe
it's a long string of yellow squares - I can't be certain). Either way, the
cursor text is correct but what gets displayed on screen is wrong.
Can anyone suggest a useful tutorial for someone who wants to find out
about libgnomecanvas? Anything that has some simple example projects
would be great.
