===============
Embedding in Qt
===============

Simple Qt application embedding Matplotlib canvases.  This program will work
equally well using any Qt binding (PyQt6, PySide6, PyQt5, PySide2).  The
binding can be selected by setting the :envvar:`QT_API` environment variable to
the binding name, or by first importing it.
