Notes from the GTK BOF in Thessaloniki

GLib

• GLib /etc/os-release support in GLib
  • Sure; open a task; Robert Ancell to propose an MR
• Ordered map/Ordered hash:
  • Sure, if someone wants to implement it
  • Put forth a strawman API proposal in GLib
• Generic container interfaces:
  • Keep specific low-level implementations of specific (non-generic) data types in GLib

  • Add high-level interfaces/wrappers as appropriate (for particular use cases) in GIO, as per GListModel/GListStore

  • The high-level implementations can use the low-level ones
  • Allows the low-level ones to be used when people know what kind of data structure they need
  • Avoids calling vfuncs everywhere
  • People to propose these as use cases appear
• Return (transfer container) (transfer full)
  • Alex to file a bug with a code example of the particular (transfer full) situation which he finds awkward, and we should iterate from there
• Write an IDL for a GVariant type, generate code to read/write it on the serialised form
  • Alex and Allison to work on this outside GLib; could be merged in later
  • Replace XML in GTK with GVariant code
• Can we switch to g_autoptr(), constructors, drop gint, C99 etc.?
  • MSVC is the problem
  • Philip to look up the current state of things and document/blog about it
• Matthias wants to move some more Unicode data into GLib from Pango
  • Sure; open a task

Dark theme support in GTK

• Still being discussed
• Outcome seemed to be: Just keep the "-dark" naming convention, and add accessors to GTK for "whats the current theme variant" and "I prefer a dark/light theme"

GTK discussion

• Unfinished things that still need to land in GTK4:
  • Listview
  • Shortcuts
  • Animations
  • Menu/Popover rework
  • Dnd
• Suggestions for new stuff:
  • a designer widget (in a separate library in gtk). Christian wants to look at this
  • add a way to have nested popover submenus
• Can we have a separate "hig library" ?
• Suggestions for stuff to move out of gtk:
  • shortcutswindow
  • about dialog (this one was not agreed)
• Suggestions for things that libhandy needs
  • better support for split headerbars and state transitions
• Blockers for application porting:
• Things not to block on: OS X backend
• Schedule discussion with ebassi:
  • 4.0 with GNOME 3.36 is not realistic
  • goals:
    • snapshot around the end the year
    • feature-complete snapshot around GNOME 3.36
    • 4.0 with 3.38
