Tag: this week in gtk

In this last week, the master branch of GTK+ has seen 40 commits, with 1551 lines added and 1998 lines removed.

Planning and status

• Matthias Clasen released the first GTK+ 3.89 development snapshot
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Andrew Chadwick landed a series of fixes for graphic tablets support on Windows
• Benjamin Otte removed the gtk_cairo_should_draw_window() utility function; the function was introduced for compatibility in the 3.x API, but now it’s not necessary any more
• Benjamin also removed gdk_window_process_updates() and gdk_window_process_all_updates(); GDK has long since been switched to a frame clock; additionally, only top level GdkWindow can be used as a rendering surface
• Lapo Calamandrei updated the High Contrast and Adwaita theme with the recent round of CSS improvements for progress bars and gradients

Bugs fixed

• 774114 – Window shadows are repainted even if only the contents of the window change
• 774695 – GtkProgressbar needs full and empty classes
• 774265 – No tilt for wintab devices
• 774699 – [wintab, potential segfault]: list iteration regression causes odd-indexed devices to be ignored during lookup & e.g. present no pressure
• 775038 – Build: Add wayland to GSKs dependencies
• 774917 – [wayland] child subsurfaces need to be placed relative to their parent
• 774893 – Application font sizes scaling gets clamped to 1.00 when starting GtkInspector
• 774939 – GtkLabelAccessible: Initialize link before setting parent
• 774760 – inspector: ensure controller is a GtkGesture
• 774686 – GtkMenu does not unref all GtkCheckMenuItem it creates
• 774743 – GtkNotebook does not unref all GtkBuiltinIcon it creates
• 774790 – GtkTextHandle does not unref all GtkAdjustment it references

In this last week, the master branch of GTK+ has seen 167 commits, with 8048 lines added and 6858 lines removed.

Planning and status

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

Notable changes

On the master branch:

• The default value of the GtkFileChooser:local-only property is now FALSE, which means that file selections dialogs will automatically show non-local resources.
• Benjamin Otte introduced the GtkSnapshot API, which works as a GskRenderNode builder for widgets, and aims to replace the immediate mode gtk_render_* family of functions.
• Benjamin also changed the GtkDrawingArea API, which now works using an explicit callback function, instead of a the generic GtkWidget::draw signal.
• Finally, Benjamin has implemented support for 3D CSS transformations in GTK+.
• The GDK API to read back the contents of a GdkWindow into a GdkPixbuf have been removed, as their behavior and result are platform-dependent.
• Matthias Clasen updated the GTK+ 3.x → 4.x porting guide, and the API reference, with the newest API additions.
• Simon Steinbeiss updated the CSS styling for GtkProgressbar to add the empty and full classes when the progress is set to 0.0 or 1.0, respectively.

Bugs fixed

• 774475 – wayland: gtk+ prevents using subsurfaces if the parent is not root
• 774476 – surfaces with no outputs get scale factor reset
• 774634 – GtkPlacesView does not unref all GDaemonFileEnumerator it references
• 773007 – GtkFilechooser gives completion for non-matching extensions
• 774609 – small fix to foreign drawing spinbutton demo
• 773587 – [PATCH] recent-manager: Add a limit to the list’s size
• 774352 – GtkAppChooserWidget does not unref all GAppInfo it references
• 774347 – Fails to build: unknown type name GdkColor
• 773601 – Display size detected as 0x0 pixels when RANDR is not available

In this last week, the master branch of GTK+ has seen 46 commits, with 1541 lines added and 3471 lines removed.

Planning and status

• Emmanuele Bassi outlined a list of items to work on GSK on the wiki
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Matthias Clasen worked on removing the custom -gtk-gradient CSS function and ensured that the standard radial-gradient and linear-gradient functions worked as defined by the CSS specifications
• Lapo Calamandrei ported Adwaita and other themes shipped by GTK+ to the standard CSS gradient definitions
• Benjamin Otte introduced a GskTexture API inside GSK to cache icon assets from GTK+ and avoid multiple texture uploads
• Timm Bäder removed the custom style properties used by GtkTreeView and GtkToolItemGroup, and replaced them with standard CSS properties
• Timm also removed the appears-as-list custom style property from GtkComboBox

On the 3.22 stable branch:

• Matthias Clasen released GTK+ 3.22.3
• Chun-wei Fan merged the HiDPI display support for Windows

Bugs fixed

• 774097 – GtkPrintOperation should not truncate job names

• 773916 – GtkComposeTable caches broken: using a same ~/.XCompose does not work twice in a row
• 773979 – GdkGLContext does not chain finalize handler
• 774046 – GtkSpinButton does not always unref priv->{up,down}_button
• 774066 – GtkHeaderBar does not unref all GtkBox and GtkSeparator it creates
• 774185 – GtkPlacesSidebar does not unref itself as many times as it references

In this last week, the master branch of GTK+ has seen 132 commits, with 10020 lines added and 16435 lines removed.

Planning and status

• Matthias Clasen worked on a better internal API for CSS gadgets to deal with the port to GSK render nodes in the wip/matthiasc/render-node-vfunc branch
• Matthias is also working on dropping deprecated API like GdkColor from the text attributes in the wip/matthiasc/text-attributes branch
• William Hua is working on adding support for ContentHub in the Mir backend for GDK, in his wip/attente/mir-content-hub branch
• The GTK+ road map is available on the wiki.

Notable changes

On the master branch:

• Alex Larsson removed the “offscreen” GdkWindow support in GDK, and the GtkOffscreenWindow widget in GTK+, in order to simplify the internals of GDK. Replacing offscreen windows is going to be the job of GSK from now on
• Alex also changed the way GTK+ is built: from now on, there won’t be a separate GDK and GSK shared libraries; instead, GTK+ will provide a single shared library that includes GDK and GSK symbols. This allows GTK to use internal symbols without having to expose them via private function pointer tables, and reduces the intra PLT jumps to call GDK API
• Chun-wei Fan improved the OpenGL support in the Windows backend of GDK; GDK will use more accurate GL configuration options, and will fall back to legacy GL contexts if core profiles contexts are not available, just like the X11 and Wayland backends
• Fan also updated the Visual Studio projects files in order to build GSK; MSVC 2013 is now the minimum required version to compile the next stable version of GTK+
• Benjamin Otte reworked the way invalidations are queued in GTK, and removed gdk_window_invalidate(); this allowed the inspector to show the updates caused by GTK widget invalidations during rendering
• Benjamin also removed the API to query visuals from GDK, and the API to check if the windowing system is using RGBA visuals and compositing has been moved to GdkDisplay from GtkWidget

Bugs fixed

• 773479 – Typo in GtkShortcutType developer docs
• 773100 – Merge libgdk.so into libgtk.so
• 773528 – Improve GL support on Windows

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

Bugs fixed

• 772922 – GtkMenu: Try using gdk_window_move_to_rect() more often
• 773029 – [gucharmap] style-set signal problem
• 773246 – Typo in css color definitions documentation
• 773180 – Don’t second-guess whether our GDK GL context is GLES
• 773113 – tests: fix clipboard test by loading correct icon
• 771694 – GtkSourceView completion popup window not shown, no grabbed seat found
• 771205 – Buttons with circular style class have a suddenly clipped shadow at the bottom

Notable changes

• Emmanuele added various compiler flags to the default build in master, in order to catch issues earlier — and, hopefully, before pushing to the remote repository — during development
• Matthias added new compiler requirements for GTK+; if you wish to build GTK+, your compiler must support at least a known subset of C99

Bugs fixed

• 772683 – Usage of FALSE instead of gint in glarea demo
• 772926 – shortcutswindow: working version of set_section_name()
• 772775 – menu bindings needs attribute to force LTR for horizontal-buttons display-hint
