Pycharm + pyqt4 Writing graphical user interface environment construction

October 27, 2016

Windows System Installation

1, Pyqt4 download installation

Pycharm on their own Baidu installed it.

PYQT4 installation package:

Https://www.riverbankcomputing.com/software/pyqt/download

My python is in the 2.7 version, and the pyqt4 here is pyqt4-4.11.4-gpl-py2.7-qt4.8.7-x32.

This bit is also very important, I started to choose 64-bit, when the. UI into a. py file when the error,

The error message is as follows

Import module times python importerror:dll load failed:%1 is not a valid WIN32 application

Workaround: Choose the 32-bit installation package, the 64-bit uninstall is good.

Click Install directly after download, the next step is good

2, Pycharm in the configuration PyQt4

Modify several places

Add Import sys

Modifies object in Ui_mainwidonw (object) to modify to Qtgui.qmainwindow

Under the Class class, add an init method:

def __init__ (self): Super (Ui_mainwindow,self). __init__ ()

Self.setupui (self)

Self.retranslateui (self)

Add the following code at the end of the code

App = Qtgui.qapplication (SYS.ARGV)

Win = Ui_mainwindow ()

Win.show ()

APP.EXEC_ ()

Execute, Interface successfully appeared

I add the following code, I do not use the above.

__name__ = =: App = qtgui.qapplication (sys.argv) MainWindow = Qtgui.qmainwindow () UI = Ui_mainwindow () ui.setupui ( MainWindow) Mainwindow.show () Sys.exit (App.exec_ ())

Although ugly, but success is OK. Hey. It's just the environment.

For the following study, the installation of the Mac version is described later. Not on time yet.
