"""A side-oriented widget similar to a TabWidget that can be collapsed and
expanded.
A Toolbox is designed to be a container for sets of controls, grouped into
'pages' and accessible by a TabBar, in the same way as a TabWidget.
A page is normally a QWidget with a layout that contains controls.
A widget can be added as a new tab using :meth:`addTab`.
The Toolbox has slots for triggering its collapse and expansion, both in an
animated mode (soft slide) and a 'quick' mode which skips the animation.
Commonly the collapse/expand slots are connected to the tabBar's
:meth:`tabBarDoubleClicked` signal. Normally in the DataLogger a Toolbox is
created and then added to a :class:`~cued_datalogger.api.toolbox.MasterToolbox`,
which connects the relevant signals for collapsing and expanding the
Toolbox.
Attributes
----------
tabBar : QTabBar
tabPages : QStackedWidget
The stack of widgets that form the pages of the tabs.
collapse_animation : QPropertyAnimation
