"""This script shows how to create a custom window around a PlotWidget.
It subclasses :class:`QMainWindow`, uses a :class:`~silx.gui.plot.PlotWidget`
as its central widget and adds toolbars and a colorbar by using pluggable widgets:
- :class:`~silx.gui.plot.PlotWidget` from :mod:`silx.gui.plot`
- QToolBar from :mod:`silx.gui.plot.tools`
- QAction from :mod:`silx.gui.plot.actions`
