Happenings on day 2

The morning was mostly filled with misc. hacking. Matthias continued to work on a content portal patch for evince, but ran into some difficulties that will need further gvfs hacking

Christian, Alex and Matthias discussed how to make GTK+ applications react to output characteristic changes ("responsive layout", if you want) The use cases we have in mind here are:

• portrait vs landscape
• widescreen vs normal
• small vs large screen
• tiled vs maximized

After comparing the APIs that Android has in this space, we came up with a few ideas:

• Add a property on GtkWindow (and GdkScreen/monitor ?) that contains this information in some coarse form (ie not exact dimensions, but just "large" or "small". Having this as a property rather than just a convenience function that returns the classification, given a width and height is that we get change notification. The property should also be user-overridable (for debugging and development)

• Add a few smart containers:
  • A box that determines its orientation depending on aspect ratio of the screen
  • A paned for a sidebar that turns into an overlay if space is scarce
  • A grid that can flexibly reattach certain children depending on size

In the afternoon, Jasper was leading a mutter session where various grievances around shadows, workspace, focus handling and tiling were aired.

We had a roadmapping session around xdg-app where we discussed topics

• Deployment / Repositories
  • Trust (not important initially for endless)
  • Discovery (not important initially for endless)
  • Metadata
    • endless current metadata: version, os-version, installed-size, languages
    • gnome-software metadata: appstream, icons, screenshots
• Build issues
  • buildtime dependencies need to be stripped out before exporting
  • helper tools for package-buased builds (like custom rpm config)
  • generate static deltas
  • multiple architectures
  • explore using the same ostree repo for host, runtimes and apps

Before we broke for dinner and bowling, Cosimo and Matt showed a list of Endless GTK+ wishlist items and bugs, including

• @media support for making css adapt to screen sizes

• Zoom support in GtkImage (may be covered by GtkImageView

• Better support for controlling sizes of widgets that can grow but should be aligned to other UI (eg ellipsizing labels)
• Support for css text-transform
• Support for css line-height
• Support for css margins
