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?
