Qt 5.7.1 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 5.7.0.
For more details, refer to the online documentation included in this
distribution. The documentation is also available online:
http://doc.qt.io/qt-5/index.html
The Qt version 5.7 series is binary compatible with the 5.6.x series.
Applications compiled for 5.6 will continue to run with 5.7.
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Qt Bug Tracker:
https://bugreports.qt.io/
Each of these identifiers can be entered in the bug tracker to obtain more
information about a particular change.
****************************************************************************
* Important Behavior Changes *
****************************************************************************
- AbstractButton, Control, and Container now calculate their implicit size
based on the implicit size of the content item plus paddings, and the
implicit size of the background item. This makes it convenient to implement
custom controls and buttons, because the implicit size calculation for
these abstract/non-visual base types works as expected out of the box, but
may cause surprises if an application relies on the old behavior that a
custom control does not have any implicit size by default.
- Drawers have been changed to follow the same visibility rules than all
other types of popups do. This means that drawers no longer stay visible
at the window edge in order to intercept input events, because that caused
severe conflicts in input handling and stacking order between multiple
drawers and other popups.
- Popups have been fixed to respect explicitly set width and height.
Previously, explicitly set size was accidentally ignored when a popup had
implicit size set.
****************************************************************************

* [QTBUG-55143] Fixed the content layout to take header and footer
visibility into account.
