This week in GTK+ – 32

In this last week, the master branch of GTK+ has seen 106 commits, with 7340 lines added and 12138 lines removed.

Planning and status
  • Matthias Clasen released GTK+ 3.89.3
  • The GTK+ road map is available on the wiki.
Notable changes

On the master branch:

  • Benjamin Otte simplified the clipping shaders for the Vulkan renderers
  • Benjamin also removed the “assume numbers without dimensions are pixels” fallback code from the CSS parser
  • Daniel Boles landed various fixes to the GtkMenu, GtkComboBox and GtkScale widgets
  • Daniel also simplified the internals of GtkComboBox and moved most of its internal widgets to GtkBuilder UI files
  • Matthias Clasen removed command line argument handling from the GTK+ initialization functions; gtk_init() now takes no arguments. Additionally, gdk_init() has been removed, as GDK ceased to be a separate shared library. The recommended way to write GTK+ applications remains using GtkApplication, which handles library initialization and the main loop
  • Timm Bäder merged his branch that makes GtkWidget visible by default, except for the GtkWindow and GtkPopover classes; Timm also removed gtk_widget_show_all() from the API, as it’s not useful any more
  • Timm modified GtkShortcutsShortcut, GtkFileChooserButton, and GtkFontButton to inherit directly from GtkWidget, taking advantage of the new scene graph API inside the base GtkWidget class

On the gtk-3-22 stable branch:

  • Ruslan Izhbulatov fixed the Windows backend for GDK to ensure that it works with remote displays
Bugs fixed
  • 777527 – GDK W32: Invisible drop-down menus in GTK apps when working via RDP
  • 770112 – The documented <alt>left shortcut doesn’t work on Wayland
  • 776225 – [wayland] dropdown placed somewhere in the screen
  • 777363 – [PATCH] wayland: avoid an unnecessary g_list_length call

This week in GTK+ – 31

In this last week, the master branch of GTK+ has seen 52 commits, with 10254 lines added and 9466 lines removed.

Planning and status
  • Alex Larsson is working on two separate branches to optimize the memory allocation and fragmentation when building the GSK render tree, after profiling the tree building code
  • Timm Bäder is working on a topic branch to switch widgets to be visible by default
  • The GTK+ road map is available on the wiki.
Notable changes

On the master branch:

  • Rui Matos added support in the Wayland backend for the gtk-enable-primary-paste settings key; this requires a newer version of the gsettings-desktop-schemas
  • Matthias Clasen and Alex Larsson refactored some of the GSK,  GtkWidget, and CSS internals to avoid excessive type casting and type checking after profiling the rendering code
  • Matthias added a “system” tab to the GtkAboutDialog widget, for free-form, system-related information
  • Matthias also updated the porting documentation for -gtk-icon-filter
  • Benjamin Otte changed the X11 backend to always call XInitThreads() unconditionally, in order to safely use the Vulkan rendering API; this should be safe, but testing is encouraged
  • Benjamin updated the GtkSnapshot API to ensure that render nodes are available only after the snapshot is complete
  • Benjamin also fixed the handling of CSS images that have no explicit size but should be scaled according to their aspect ratio
  • Timm Bäder added a revealed property to the GtkInfoBar widget and ported the GtkActionBar code to use it

On the gtk-3-22 stable branch:

  • Ruslan Izhbulatov worked on fixing various cases of keyboard handling under Windows, including interaction with AeroSnap; Ruslan also fixed bug 165385, which was going to be 12 years old in 10 days
  • Carlos Garnacho changed the EGL handling inside the Wayland backend to disable swap interval, as the compositor is in charge of timing the rendering
  • Matthias Clasen deprecated additional API that has been removed from the development branch
Bugs fixed
  • 776031 – W32: Winkey+down minimizes maximized window instead of restoring it
  • 165385 – Win32 keyboard handling still incomplete
  • 769835 – On Wayland, application containing GtkGLArea stops responding if it’s not on current workspace
  • 774726 – GtkTreeView dnd: gtk_drag_finish remove row when reorder sinse 3.20
  • 769214 – keyval field not filled correctly for Pause key
  • 776485 – GDK W32: Impossible to restore maximized window via system menu
  • 776604 – about dialog: Add a “system” tab
  • 775846 – gdk/wayland: Add support for the gtk-enable-primary-paste gsetting

This week in GTK+ – 30

In this last week, the master branch of GTK+ has seen 81 commits, with 12205 lines added and 12625 lines removed.

Planning and status
  • Welcome back to This Week in GTK+ after the end of the year break
  • The GTK+ road map is available on the wiki.
Notable changes

On the master branch:

  • Timm Bädert merged his work on moving the scene graph of widgets directly into the GtkWidget class; this allows widgets to have internal children without necessarily subclassing GtkContainer
  • Timm also worked on porting widgets currently using the internal CSS gadget API to be composite widgets, like GtkSwitch
  • Benjamin Otte and Georges Basile Stavracas Neto have been working on making the Vulkan GSK renderer work on Wayland
  • Benjamin also worked on improving the efficiency of the Vulkan renderer
  • William Hua worked on improving the Mir backend of GDK with regards to clipboard support

On the gtk-3-22 stable branch:

  • Matthias Clasen released GTK+ 3.22.6
Bugs fixed
  • 776627 – Correct PostScript capitalization
  • 776868 – Improve the documentation of GtkEntry:attributes
  • 776560 – icon-browser: window opens at very narrow size, only showing 1 column of icons
  • 775732 – mir: clipboard support missing
  • 776736 – build: Fix vulkan detection
  • 776807 – GtkInspector doesn’t show up when Gtk is initialized through option group
