Features Being Planned For HTML5 GTK+

GNOME

Earlier this week when multi-process support was added to the HTML5 back-end in GTK+, a TODO list was also created that hints at some of the features being looked at for the "Broadway" back-end.

Broadway is a back-end to the mainline GTK+3 tool-kit that allows for GTK applications to be rendered within HTML5 web-browsers. It's progressed a lot since originally being introduced in late 2010 and then being merged in 2011 for GTK+ 3.2, but still it's mostly a toy for now. The multi-process support merged this week is notable in that multiple GTK applications can run within a single web-page, treated similar to an X11 session.

When the multi-process support was merged for Broadway, a TODO list was added with this commit. The features being listed as TODO work for this HTML5 back-end include:

- Cache surfaces that are opened via shm_open inbetween updates.
- Send configure event when a window is moved and no client
- Handle implicit grabs when in broadway-server.c
- Rewrite events (per-client serials, etc)
- Keyboard focus handling
- Add resize handling to js WM
- Make canvas/title non-selectable in browser
- Handle browser window size changes
- _gdk_broadway_server_has_client is always FALSE, so resize don't work
- Send reset events on client disconnect (button up, normal state. Maybe grab state reset?)
- RGBA suport
- Shift-select in gedit doesn't work
- Backdrop mode

Let's see what happens to the Broadway HTML5 back-end in 2013...
