Install and use pyqt in Windows

Download the pyqt installation file for the Python version from the following link.

Http://www.riverbankcomputing.co.uk/static/Downloads/PyQt4

 

Here I selectPyQt-Py2.7-gpl-4.8.1-1.exe

 

1. Click Install. After installation, check whether the installation is complete. You can use from pyqt4.qtgui import * to test the installation.

 

If no error is reported, pyqt is successfully installed.

 

2. After the installation is complete, open the shell. Enter the following Python code

Import sys <br/> from pyqt4.qtgui import * <br/> A = qapplication (sys. argv) <br/> W = qwidget () <br/> W. resize (1, 320,240) <br/> W. setwindowtitle ("Hello, world! ") <Br/> W. Show () <br/> sys.exit(a.exe C _()) 

 

When running the above Code, you may report an error because the pyqt4 package is not within the scope of the system search, so the module cannot be imported.

 

Set

Print sys. Path

SYS. Path. append (r 'd:/python27/lib/Site-packages/pyqt4 ')

Print sys. Path

 

Added before import from pyqt4.qtgui *.

 

The code above will display a small window on the screen.

 

Now you have installed pyqt and completed the first simplest instance.
