---------------
ubuntu-ui-toolkit (1.3.1627+15.10.20150908-0ubuntu1) wily; urgency=medium
[ Zsombor Egri ]
* Implement list item expansion.
* Turn AdaptivePageLayout page creation to be asynchronous.
* Fix ListItem swipe handling when gesture is initiated over an overlay
MouseArea which does not accept pressed event. Fixes LP: #1484545
* AbstractButton to C++. Fixes LP: #1365471, LP: #1458028
* Haptics singleton moved to C++.
* ActionItem moved to C++.
* Making columns resizable in an AdaptivePageLayout.
* Introducing column configuration into AdaptivePageLayout.
[ Benjamin Zeller ]
* Fix build inside qt and shadowbuild.
[ Tim Peeters ]
* Remove old and unused header-related files, and update unit test filenames.
* Don't unset the subheader style when Page.head changes because that unsets
the parent of Page.head.contents. Fixes LP: #1488922
* Fix the theming of the MainView.
* Fix the background color of the overflow panel.
[ Christian Dywan ]
* Include change signals with arguments in .api.
* A public QML type with no version is an error. Rather than silently breaking
as QML does normally at least apicheck can make this fatal.
* UbuntuShape shouldn't emit redundant deprecation warnings. Fixes LP:
#1481791
* Update .bzrignore to new upstream style layout. Fixes LP: #1433308
* Revert unnecessary change of Popover minimumWidth. Fixes LP: #1483708
[ Ken VanDine ]
* Fixed a few typos in the api docs for StateSaver.
[ Olivier Tilloy ]
* Take custom key indexes into account to allow sorting on custom roles.
Fixes LP: #1485674
[ Albert Astals Cid ]
* Properly free shapeTextures[index] The old code assumes that the UbuntuShape
will still be around when the opengl context is destroyed, but that seldom
happens so connect the signal to a lambda that will be there and does the
cleanup properly. Without this patch testDirectionalDragArea from unity8 was
hitting the qFatal because it ran out of space in shapeTextures.
[ Richard Huddie ]
* Remove all usage of the autopilot simulated keyboard when the OSK is being
used. Fixes LP: 31483668
[ Gerry Boland ]
* Compensate for Qt's device pixel ratio multiplier.
Fixes: LP: #1207270, LP: #1275748, LP: #1468402
[ Nick Dedekind ]
* Added relative date time i18n.
[ CI Train Bot ]
* Resync trunk.

Title:
Ubuntu QPA plugin does not override QScreen::devicePixelRatio
Status in qtubuntu:
In Progress
Status in qtubuntu package in Ubuntu:
Confirmed
Status in ubuntu-ui-toolkit package in Ubuntu:
Fix Released
Bug description:
In bug 1257721, I made Oxide DPI aware by passing an appropriate
device pixel ratio to Chromium. However, the way this is implemented
on Ubuntu is not really ideal. I expected to be able to read the DPR
from QScreen::devicePixelRatio, but this is always 1.0f on Ubuntu
regardless of the device scale. Instead, device pixel independence is
implemented entirely in ubuntu-ui-toolkit by providing a QML component
for converting between grid units and device pixels, based on an
environment variable called "GRID_UNIT_PX".
For now, I implemented a workaround in Oxide to also set the DPR to
GRID_UNIT_PX / 8 when running with the Ubuntu platform plugin, and
QScreen::devicePixelRatio on all other platforms.
I think that qtubuntu should instead override
QScreen::devicePixelRatio (that could still come from the same
environment variable for now), and ubuntu-ui-toolkit should do the
conversion from grid units to device pixels using this instead.
