qt: Qt bindings

Common wrapper over Python Qt bindings:

• PyQt5

• PySide2

• PySide6

If a Qt binding is already loaded, it will use it, otherwise the different Qt bindings are tried in this order: PyQt5, PySide2, PySide6.

The name of the loaded Qt binding is stored in the BINDING variable.

This module provides a flat namespace over Qt bindings by importing all symbols from QtCore, QtGui, QtWidgets and QtPrintSupport packages and if available from QtOpenGL and QtSvg packages.

Example of using silx.gui.qt module:

>>> from silx.gui import qt
>>> app = qt.QApplication([])
>>> widget = qt.QWidget()

For an alternative solution providing a structured namespace, see qtpy.
