In this last week, the master branch of GTK+ has seen 33 commits, with 5011 lines added and 8140 lines removed.

Planning and status

• The GTK+ road map is available on the wiki
• Patrick Griffis is experimenting with a feature branch to deprecate and remove gtk_dialog_run(); see this comment on the pitfalls of nested main loops with regards to UI threads, IPC threads, and I/O threads
• Matthias Clasen is experimenting with re-using the fuzzy search in libdazzle in the icon browser

Notable changes

On the master branch:

• Matthias Clasen added the ability to copy the icon name to the clipboard to the icon browser utility

• Olivier Fourdan fixed various bugs in the Wayland backend, and backported the fixes to the gtk-3-22 stable branch
• Chun-wei Fan pushed various fixes to ensure that GTK+ keeps building with MSVC on Windows
• Emmanuele Bassi modified the Meson build to ensure that all the SASS-based themes are regenerated when building GTK+, if sassc is installed; Lapo Calamandrei removed the Gem file for Ruby/Sass, and thus GTK+ switched to sassc as the preferred SASS compiler

Bugs fixed

• 770513 – MainToolbar in full-screen mode has rounded corners, which show video pixel bleed-thru underneath it
• 783347 – gtkfilechoosernativewin32: Fix support for non-ASCII paths
• 781945 – SIGSEGV dragging window on Wayland when toplevel window set_transient_for is set to another toplevel

After quite a long break around the GNOME 3.24 release, we’re finally back. Sorry for the wait!

In this last week, the master branch of GTK+ has seen 103 commits, with 2355 lines added and 5482 lines removed.

Planning and status

• The GTK+ road map is available on the wiki.
• Matthias Clasen released GTK+ 3.91.0, the first snapshot of the development cycle that will lead to the 3.92 release. This is still part of the development cycle towards the API stable 4.0.
• Timm Bäder is working on his drawing branch which aims to replace all the internal uses of CSS gadgets with real widgets. See this article on this blog for more information.

Notable changes

On the master branch:

• Carlos Garnacho merged his event-delivery branch, which moves the event handling from the GDK window hierarchy to the GTK widget one; this is the first step towards the removal of all GdkWindow instances outside of the top level one, and which will ultimately lead to improved input handling.

Bugs fixed

• 745289 – wayland: do not use g_error() on connection errors

The past two weeks we’ve had DevConf and FOSDEM back to back, so the development slowed down a bit. Expect it to pick up again, now that we’re close to the GNOME 3.24 release.

In these last two weeks, the master branch of GTK+ has seen 34 commits, with 20973 lines added and 21593 lines removed.

Planning and status

• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Timm Bäder removed gtk_widget_class_list_style_properties() in the continuing effort to deprecate the style properties inside GtkWidget and replace them with CSS properties
• Timm also moved some of the state used only by GtkToggleButton subclasses into those types
• William Hua improved the Mir GDK backend for proper positioning of menus

Bugs fixed

• 777547 – Notebook arrow icon wrong color after closing final tab
• 773686 – Software when launched shows in dash with wrong icon, name and menu
• 775864 – getting-started: typo tie->the
• 778009 – menu drawn on top of menubar in Fedora

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

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

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

In this last week, the master branch of GTK+ has seen 20 commits, with 883 lines added and 2740 lines removed.

Planning and status

• Alex Larsson worked on a simplification of GdkWindow that removed native and foreign child windows; the long term plan is to have native windowing system surfaces only for top levels
• Alex also sent a review on gtk-devel-list of Benjamin’s wip/otte/rendernode branch, with ideas on future work for the GSK rendering API
• Chun-wei Fan updated the Windows backend to ensure that it continues to build and work on the master branch
• Benjamin Otte implemented the snapshot() virtual function in more GtkWidget subclasses.
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Olivier Fourdan updated the Wayland backend to ensure that empty input shapes are updated on sub-surfaces when needed; this allows other toolkits, like Clutter, to use the GDK sub-surface API
• Alex Larsson removed gdk_window_reparent() from the GDK API, since it’s unused and allows for the goal of only having top level GDK windows
• Benjamin Otte removed the ad hoc code from GdkCellView to modify its background, as the cell view can use CSS to achieve the same (or better) results
• Benjamin also removed the border node from the GtkFrame CSS nodes, as it performed additional immediate mode clipping that complicates the rendering

On the gtk-3-22 stable branch:

• Emmanuele pushed fixes for the GL rendering when using GtkGLArea with OpenGL ES 2.0 implementations that are missing the GL_EXT_framebuffer_blit extension

Bugs fixed

• 776132 – Mention the difference between gdk_window_create_similar_image_surface and cairo_surface_create_similar_image
• 774534 – [wayland] input shape and opaque region not applied without begin_paint()/end_paint()

In this last week, the master branch of GTK+ has seen 103 commits, with 5986 lines added and 1896 lines removed.

Planning and status

• Benjamin Otte is working on a refactoring of the GSK render node API
• Emmanuele Bassi worked on a 3.x-specific branch that allows GDK to use EGL instead of GLX on X11 platforms
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Benjamin merged the Vulkan renderer for GSK, as comparison point for the GL and Cairo renderers. The Vulkan renderer adds a new optional dependency on a working Vulkan implementation, as well as glslc
• The Vulkan renderer also resulted in a large refactoring of the GL drawing code inside GDK, though this should not have caused any user-visible changes in the API
• Benjamin also implemented support for the CSS border-spacing property following the CSS 2.1 specification

On the gtk-3-22 stable branch:

• Matthias released GTK+ 3.22.5.

Bugs fixed

• 775651 – GdkX11-4.0.gir, GdkWin32-4.0.gir, and Gsk-4.0.gir are generated before Gdk-4.0.gir is ready

In this last week, the master branch of GTK+ has seen 65 commits, with 1780 lines added and 2429 lines removed.

Planning and status

• A GTK+ hackfest is planned for March 2017; the main topic is going to be improving performance, especially with regards with rendering
• Benjamin Otte is reworking the GL renderer for GSK to ensure it’s well integrated into the GDK rendering
• Additionally, Benjamin is also working on an experimental Vulkan-based renderer for GSK
• Timm Bäder is changing the GtkWidget and GtkContainer API to converge the two classes into a single scene graph
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Matthias Clasen changed GTK to exit cleanly when it loses the display connection under X11 and Wayland; this change has also been backported to the stable gtk-3-22 branch
• Timm Bäder cleaned up various widgets to consistently use gtk_widget_measure() when measuring the size of their children
• Daniel Boles fixed a bug in GtkComboBox that caused a warning in Debian-based distribution that applied a downstream patch; see bug 771242 for more information; this change has also been backported to the stable gtk-3-22 branch

On the gtk-3-22 stable branch:

• Lapo Calamandrei backported the GtkProgressbar theme fixes for correctly identifying empty and full states

Bugs fixed

• 774915 – [Wayland]: Destroying the parent of a subsurface causes _gdk_window_destroy_hierarchy: assertion failed
• 771242 – 3.21: opening menu for certain types of GtkComboBox causes Gdk-CRITICAL assertion ‘GDK_IS_WINDOW (window)’ failed
• 775410 – gsk/Makefile.am runs g-ir-scanner before libgsk-4.la is linked
• 775319 – [Wayland]: gdk_window_get_toplevel() fails to return the toplevel of a child subsurface
• 775316 – gtk_drag_source_set_icon_pixbuf references the pixbuf received once too much
• 775212 – GtkScaleButton does not unref all GtkAdjustment it references
• 775525 – gtk_flow_box_get_child_at_index shouldn’t crash with an invalid index
