Well, here's what I need -- maybe there's other way to achieve it: I need to draw identifiers to some kinds of selections (may be lines, crosses, ...) on an unpredictable varying background, which is actually a display of some data. So I'd like - visibility on varying backgrounds - obscuring as little of the underlying bg as possible - ease of undrawing - portability gdk_draw_string() with GDK_XOR/GDK_INVERT has first three properties, but requires some backend-dependent font guesswork and it is deprecated so I wonder whether it will survive to Gtk+3.0... I'm unable to get anything else than portability from gdk_draw_layout(), that is useless in itself. It should be possible to draw the text to an offscreen drawable and then draw that with GDK_XOR. But how do I get rid of antialiasing (that don't work well with XOR)?
