Minutes of the meeting at GUADEC

Agenda

• roadmap, especially outstanding HIG items and Glade

  • Projects/GTK+/Roadmap

  • continue the discussion from the DX hackfest in Berlin, May 2014
    • in-app notifications
    • Glade
    • data model
      • branch ready to land

      • similar to GMenuModel

      • collection is always ordered
      • interface + base implementations

      • based on GSequence

      • objects in the model → proxies in the view; use GBinding to connect them

      • may have some implementation that does not create 1:1 collection items/UI proxies
      • trees?
        • various strategies — simple collapsing, per-item property holding a collection
        • possibly punted
      • integration with scrolling containers, especially for infinite/paged model population
      • views

        • do we modify GtkListBox or add a new class?

          • deprecating GtkListBox and GtkFlowBox is not appealing

          • we could make them special cases of views with implicit models containing widgets
          • selection/filtering/sorting API on the view does not work with a model-backed view
      • moving forward
        • target: 3.16
        • needs a view first
        • possibly have an Egg copy-and-paste iteration

    • styling of GtkListBox rows

      • separators between rows are currently painful

      • https://bugzilla.gnome.org/show_bug.cgi?id=731911

      • need first/last-child support
      • possibly nth-child, but this requires some optimization first to reduce the number of computed style objects and widget paths

    • GtkFlowBox improvements for cell resizing and reflowing

    • selection mode
    • in-app notification

      • GdNotification widget

  • Glade?
    • hard to support new containers
    • makes it harder to improve support for new widget

    • add meta-information for the Glade UI in the GtkBuilder definition?

    • add Glade support as a strict requirement for including new widgets inside GTK+?
    • move Glade previewer binary into GTK+
      • use with custom GTK+ builds
• Testing
  • ref testing
  • interactive testing
  • do we need better scaffolding?
    • we have already some in place
  • interactive tests for gestures
    • especially conflicts between gestures
• GSK/Scene graph
  • target: 3.16/3.18
  • base requirements
    • being able to build UIs with GSK inside GTK widgets
    • being able to embed GTK widgets into GSK elements
  • port GNOME apps from Clutter/Clutter-GTK/Clutter-GStreamer to GSK as a validation path
• Roadmap/4.0
  • porting widgets to the scene graph will probably require an API break
    • once GSK lands we can start looking at people porting custom widgets to GSK
  • input/gestures
    • widgets should start replacing their input event handling to gestures right now
• Wayland status
  • grabs
    • OSK/popup contention
    • grab emulation?
    • how much of the X11 behaviour do we want to maintain when emulating?
    • per-application/per-window emulated grab
    • device grabs replace global/window grabs
  • improve test harness for Wayland
    • similar to how we use Xvfb for X11
  • clipboard
    • mostly "good enough" for 3.14
    • needs to be cleaned up for 3.16
  • top-levels and widget-attached top-levels
• windows and top-levels

  • lots of code in GtkWindow and GdkWindow is there to deal with X11-specific complexity

  • we should move that code into its own class
  • would simplify the size management code on non-X11
  • would also simplify the life of Glade with embedded "top-levels"
• non-Linux backends
  • merging theme and icons make GTK+ does not make apps look bad by default
  • nacho and LRN are landing build fixes
  • can we make a gnome-icon-theme GResource build for non-Linux builds?
