Whiteboard

Prototype code: https://code.launchpad.net/~gerboland/ubuntu-ui-toolkit/layoutmanager/
Demo: https://code.launchpad.net/~gerboland/+junk/googleio-layout/
Demo Code: http://paste.ubuntu.com/5670914/

[Ideas]
Allow defining layouts based on available input devices (keyboard, mouse, touch, etc)
Signals or property change events on current layout changed
LayoutManager uses a default layout for child components, this is used when no other defined layout's "when" matches
LayoutManager uses the first matching Layout, in cases where more than one matches
Would be nice for the device simulator to have pre-defined profiles for different devices, including pixels/gridunit
"WARNING: there is no layout available for screens wider than 80gu. WARNING: there are two layouts available when screen width is less than 15gu."

Available in Beta timeframe

Work Items

Work items for ubuntu-13.07:
[mhall119] Blog about how to use the LayoutManager API: TODO
[mhall119] Put together a community initiative to develop pre-defined layouts: TODO

Work items:
Determine which part of the stack determines pixels-per-GU, how it does it, and who controls that part of the stack. And tell everyone about it so we can all talk about whether the method will actually work: TODO
[calumpringle] Work on designs for responsive layouts with Ubuntu components: TODO
