If you are new to Python PyQt, then I highly recommend this book. On Ubuntu Linux / Debian Linux you can use the command: 1
Which package manager to use depends on which Linux distribution you are using. You can install PyQt your software package manager. This isn’t hard to do if you have some Linux experience. Once you have Python ready, the next step is to install PyQt. On Ubuntu Linux they sometimes include two versions of python, python3 and python. You can verify that you have the newest Python version with the command: 1 But you want to make sure to use Python 3, because of all the features and ease of use. Python is often installed by default on Linux (in nearly all of the distributions including Ubuntu). You can use brew to install pyqt (in the terminal): 1 This installs the PyQt GUI library.īut to use it from Python, you also need Python module. The first step to take is to install the Mac OS X binary. The Qt installation package qt-opensource-mac-圆4- 5.11.3. On Apple Mac OS X installation is a bit simpler. The used Qt installation packages for OS X (qt-opensource-mac-圆4-5.11.3.dmg) contains the matching Qt Creator, which means it does not need to be separately searched for and downloaded and installed, as assumed above. On Python >= 3.6, you can also try this command: 1 It’s not necessary to compile everything from source, you can install all the required packages with the installer. Check the box to add all of the PyQt5 extras. Next you want to install a Python version 3.3 or newer. To install PyQt on Windows there are a few steps you need to take.įirst use the installer from the qt-project website, from qt to install PyQt.

In this article you’ll learn how to install the PyQt module.ĭesktop applications made with PyQt are cross platform, they will work on Microsoft Windows, Apple Mac OS X and Linux computers (including Raspberry Pi). The PyQt module can be used to create desktop applications with Python. It seems to use the Quicktime backend automatically.PyQt is often not installed by default. I also don't know how to specify an alternate backend for Phonon on OS X.
Qt mac os x check for mac os x#
I attempted to compile the phonon-vlc backend ( ) for Mac OS X as a work-around, but I wasn't able to get it to build. As an unrelated feature request, it would be nice to have OpenGL acceleration on Mac OS X for videos in GraphicsViews, especially once QtQuick/QML gains popularity.)
(It seems that the QImage-based rendering functions are used in both cases, even when a GL context is available. The crash happens regardless of whether a QGLWidget is used for the GraphicsView viewport or not.
For me, it usually happens a random number of seconds (usually 15 or less) after video starts playing. The crash seems to be a threading bug, so it doesn't happen immediately.
Qt mac os x check movie#
Before running, you'll need to place the test movie (testMovie.m4v) into the same folder as the compiled application bundle (PhononGraphicsViewBugDemo.app), or use any other video file you have handy. I've attached a minimal program to reproduce the bug.
The crash is always inside Phonon::QT7::VideoFrame::drawQImage(). (Video Widgets inside QGraphicsViews seem to be very desirable, so that you can do composition and draw graphics and widgets on top of videos. When using the Cocoa (64-bit) build of Qt on Mac OS X, placing a Phonon::VideoWidget inside a QGraphicsView causes the Phonon Quicktime backend to crash.
