RE: GtkText Problems Update

["Dugas, Alan" <alan dugas analog com>]

You could simplify the code and eliminate variables temp and size using;

gtk_text_backward_delete(GTK_TEXT(text),
gtk_text_get_length(GTK_TEXT(text));

Hope this helps.

P.S.
When using the gtk_editable_get_chars() method, don't forget to free() temp
when you are done.
