Month: November 2016

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

• 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

• 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
• 774614 – Wrong #include in Print docs
