This section provides an overview of what PyQt4 is, and why a developer might want to use it.PyQt is a GUI widgets toolkit. It is a Python interface for Qt, one of the most powerful, and popular cross-platform GUI library.
PyQt is a blend of Python programming language and the Qt library. This introductory tutorial will assist you in creating graphical applications with the help of PyQt.It should also mention any large subjects within PyQt4, and link out to the related topics. Since the Documentation for PyQt4 is new, you may need to create initial versions of those related topics. Basic Hello World Program import sysfrom PyQt4 import QtGuidef window:app = QtGui.QApplication(sys.argv)w = QtGui.QWidgetb = QtGui.QLabel(w)b.setText('Welcome to PyQt4 SO Documentation!' )w.setGeometry(100,100,550,65)b.move(50,20)w.setWindowTitle('PyQt4 Hello World Demo')w.showsys.exit(app.exec)if name 'main':windowInstallation or SetupDetailed instructions on getting pyqt4 set up or installed. Windows. Mac.
LinuxIf you want to install the version specific to your system python version and you system configuration(32-bit or 64-bit) then go to this and download and install the package. You can install the.whl file simply by going to command prompt pip install PyQt4‑4.11.4‑cp34‑none‑winamd64.whl.Go a head Install the software and Start Building Awesome GUI!!
I am about to start developing using PyQT, but there seem to exist two versions.
Python 2.7 Install Pyqt4
Here are Windows wheel packages built by Chris Golke - In the filenames cp27 means C-python version 2.7, cp35 means python 3.5, etc. Since Qt is a more complicated system with a compiled C codebase underlying the python interface it provides you, it can be more complex to build than just a pure python code package, which means it can be hard to install it from source. Make sure you grab the correct Windows wheel file (python version, 32/64 bit), and then use to install it - e.g: C: path where wheel is pip install PyQt4-4.11.4-cp35-none-winamd64.whl Should properly install if you are running an x64 build of Python 3.5.
If you install PyQt4 on Windows, files wind up here by default: C: Python27 Lib site-packages PyQt4. but it also leaves a file here: C: Python27 Lib site-packages sip.pyd If you copy the both the sip.pyd and PyQt4 folder into your virtualenv things will work fine. For example: mkdir c: code cd c: code virtualenv BACKUP cd c: code BACKUP scripts activate Then with windows explorer copy from C: Python27 Lib site-packages the file (sip.pyd) and folder (PyQt4) mentioned above to C: code BACKUP Lib site-packages Then back at CLI: cd.
(c: code BACKUP) python backup.py The problem with trying to launch a script which calls PyQt4 from within virtualenv is that the virtualenv does not have PyQt4 installed and it doesn't know how to reference the default installation described above. But follow these steps to copy PyQt4 into your virtualenv and things should work great. Amos and josh ft rabbit mp3 download.
