[Python-modules-team] Bug#779369: pyqt5-examples missing dependencies python3-pyqt5.{qtquick, qtopengl, qtmultimedia, qtsvg} etc.

[Chris Bainbridge]

Package: pyqt5-examples
Version: 5.3.2+dfsg-3
Severity: normal

Dear Maintainer,

pyqt5-examples should depend on all the libraries necessary to run the
examples.
For example:

    $ /usr/share/doc/pyqt5-examples/examples/qtdemo/qtdemo.py
    Click on Quick > Animation > Launch : Nothing happens

    $ python3
/usr/share/doc/pyqt5-examples/examples/quick/animation/animation.py
Traceback (most recent call last):
  File "/usr/share/doc/pyqt5-examples/examples/quick/animation/animation.py",
line 49, in <module>
    from PyQt5.QtQuick import QQuickView
ImportError: No module named 'PyQt5.QtQuick'

etc.

Also note there is another missing dependency: python3-pyqt5.qtopengl should
depend on python3-opengl (the opengl demos need python3-opengl but even after
install python3-pyqt5.qtopengl it is not installed). Even after that, an opengl
demo seems to not work:

    $ /usr/share/doc/pyqt5-examples/examples/qtdemo/qtdemo.py
    Click on OpenGL > OpenGL Window > Launch: Crash/Hang (?)

    $ python3 /usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py
    Traceback (most recent call last):
      File "/usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py",
line 115, in exposeEvent
        self.renderNow()
      File "/usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py",
line 95, in renderNow
        self.m_gl = self.m_context.versionFunctions()
    ImportError: No module named 'PyQt5._QOpenGLFunctions_3_0'
    Traceback (most recent call last):
      File "/usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py",
line 115, in exposeEvent
        self.renderNow()
      File "/usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py",
line 100, in renderNow
        self.render(self.m_gl)
      File "/usr/share/doc/pyqt5-examples/examples/opengl/openglwindow.py",
line 165, in render
        gl.glViewport(0, 0, self.width(), self.height())
    AttributeError: 'NoneType' object has no attribute 'glViewport'
