I am not sure what you mean by column number as each character may have a different width. If you are asling how many characters are on the line before the current position, you could call gtk_text_iter_get_offset(), gtk_text_view_backward_display_line_start() and then call gtk_text_iter_get_offset() again. The determine the line number you could call gtk_text_view_backward_display_line() until gtk_text_iter_is_start() is TRUE counting the number of times you call the function. I am not sure whether there is a better way. > 2. I should put this code piece into a callback function, but which signal > should I connect the function with?

I didn't find any function call to implement this. > _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
