+"""This script shows how to subclass :class:`PlotWidget` to tune its tools.
+
+It subclasses a :class:`silx.gui.plot.PlotWidget` and adds toolbars and
+a colorbar by using pluggable widgets:
+
+- QAction from :mod:`silx.gui.plot.actions`
+- QToolButton from :mod:`silx.gui.plot.PlotToolButtons`
+- QToolBar from :mod:`silx.gui.plot.PlotTools`
+- :class:`ColorBarWidget` from :mod:`silx.gui.plot.ColorBar`.
