This Week in GTK+ – 21

In this last week, the master branch of GTK+ has seen 335 commits, with 13631 lines added and 37699 lines removed.

Planning and status

• Emmanuele merged his wip/ebassi/gsk-renderer branch into the master branch, effectively adding GSK to the API; there is an ongoing effort in improving its performance profile, as well as porting more widgets to the GskRenderNode API
• Benjamin added new GdkWindow constructors for input and child windows, which will eventually replace the generic gdk_window_new() API
• Timm removed more deprecated API from GTK+
• Timm also replaced all the get_preferred_* family of virtual functions with a single GtkWidgetClass.measure virtual function, thus simplifying the implementation of widgets
• Matthias started a new migration guide for application developers that wish to port their code from GTK+ 3.x to GTK+ 4.x
• Chun-wei Fan updated the Windows backend of GDK following the deprecations and API changes
• The GTK+ road map is available on the wiki.

Notable changes

• GDK now tries to do a better job at detecting if a GL context is using OpenGL ES, a core OpenGL profile, or a legacy OpenGL profile.
• New deprecations in the gtk-3-22 branch for API that has been removed from the master branch:
  • gdk_window_set_debug_updates() — will be replaced by appropriate rendering in GSK
  • GtkContainer:child — no replacement, as it’s just a C convenience property for use in variadic arguments functions
  • gdk_window_set_background* family of functions — no replacement
  • gdk_window_set_wmclass() — no replacement, as it was already marked as “do not use”
  • gdk_drag_dest_set_proxy() — no replacement
  • various GdkScreen API — replaced by GdkMonitor
• Jaime Velasco Juan vastly improved the “native” Windows theme in the gtk-3-22 branch, to better match the Windows 7 visuals
• Lapo Calamandrei has fixed the appearance of circular buttons in Adwaita
