function gtk.Widget.Widget.addOnDraw is deprecated

[iK4tsu]

I want to work with gtk.DrawingArea, however the only way (that I know of) to draw is to connect with the signal addOnDraw. From my research the upcoming Gtk release, Gtk4, the gtk.Widget won't have the addOnDraw signal, and instead gtk.DrawingArea will have a gtk_drawing_area_set_draw_func, link https://developer.gnome.org/gtk4/stable/GtkDrawingArea.html#gtk-drawing-area-set-draw-func.

How should I proceed now? Should I keep using the addOnDraw signal until the new major update and then fix it when it breaks, or is there other way to do it?

Currently the only thing you can do is keep using the signal and change the implementation when switching to GTK4.

Ok, thank you!
