Minimal Qt
==========

Minimal PyQt example that displays an image.

`Figure.show()` returns a QWidget that you can use in a Qt app just like any other QWidget!

.. GENERATED FROM PYTHON SOURCE LINES 9-36

.. code-block:: Python


    # test_example = false

    # import Qt or PySide
    from PyQt6 import QtWidgets
    import fastplotlib as fpl
    import imageio.v3 as iio

    img = iio.imread("imageio:astronaut.png")

    # fastplotlib and wgpu will auto-detect if Qt is imported and then use the Qt canvas and Qt output context
    figure = fpl.Figure()

    figure[0, 0].add_image(img)

    # must call fig.show() to start rendering loop and show the QWidget containing the fastplotlib figure
    qwidget = figure.show()

    # set QWidget initial size from image width and height
    qwidget.resize(*img.shape[:2])

    # execute Qt app
    # if this is part of a larger Qt QApplication, you can also call app.exec() where app is the QApplication instance
    fpl.run()

    # You can also use Qt interactively/in a non-blocking manner in notebooks and ipython
    # by using %gui qt and NOT calling `fpl.run()`, see the user guide for more details
