This week in GTK+ – 29

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()
