Il gruppo di sviluppo di Gtk+ sta lavorando alla roadmap per lo sviluppo delle nuove librerie Gtk+ 3.0.

Per ora c’è una prima stesura da cui partire e discutere come implementare tutti i cambiamenti e come portare avanti le nuove funzionalità. Potete seguire la discussione sulla mailing list oppure leggere la roadmap.

• Full offscreen rendering, probably completed in 2.x. This is needed for animations and effects beyond the classic widget boundaries.
• Remove all public structure fields so the API is defined only in terms of function entry points.
• Introduce new widget creation means that fix currently problematic widget property defaults like widget visibility.

• Eliminate the need for implementing realize/unrealize, map/unmap, style_set and more, depending on how much offscreen rendering allows for this.
• Implement a new base class widget for scrollable widgets that could help to simplify the implementation of widgets like text-view, scrolled window, tree-view.
• Resolution independence, this allows free scaling of UIs, including fonts, pixmaps and spacing/padding.
• Anything from the current 2.16 list that didn’t make it in time:
  • support for icons in entries
  • better handling of invisible characters
  • flippable boxes, separators, etc
  • resolution independence/font scaling
  • complete offscreen window support
  • extended layout (width-for-height)
  • a tool palette widget
  • a simple list API
• Simplified DnD API, work on this is going on in the tree-view already.
• Add simple transparency API for widgets (should work by means of offscreen rendering if XComposite isn’t available).
• Allow themable RGBA backgrounds for widgets.
