Python3+PyQt5+PyCharm 桌面GUI开发环境搭建

一、安装python

PyQt5所支持的python版本是不低于3.5版本

python3.5以上的版本安装:https://www.python.org/downloads/windows/

二、安装PyQt5

pip install PyQt5
pip install PyQt5-tools

三、配置pycharm

官网下载安装pycharm:https://www.jetbrains.com/pycharm/

1,点击:File -》Settings

3,设置Qt Designer

修改三个地方,其他地方默认:

Name:Qt Designer
Programs:D:\Program Files\Python35\Lib\site-packages\pyqt5-tools\designer.exe
Working directory:$ProjectFileDir$

注意:Programs参数需要修改为你电脑里边的“designer.exe”路径。

4,配置PyUIC

设置四个地方,其他可以默认
Name:PyUIC
Programs:D:\Program Files\Python35\python.exe
Parameters:-m PyQt5.uic.pyuic  $FileName$ -o $FileNameWithoutExtension$.py
Working directory:$ProjectFileDir$

注意:Programs参数需要修改为你电脑里边的python“python.exe”路径。

3,从左边 1区 拖拽,注意是“拖拽”控件到工作区,修改对应属性

4,做完基本的界面设置之后,会看到同目录下生成了一个“.ui”的文件

5,右键 External Tools -》PyUIC ,将“.ui”文件转为“.py”文件

6,这时,如果一切正常,没有报错的话,会在同目录下生成对应的“.py”文件

7,将下面的代码,放到生成的“.py”文件,放到最后就行(注意缩进)

if __name__=="__main__":
    import sys
    from PyQt5.QtGui import QIcon
    app=QtWidgets.QApplication(sys.argv)
    widget=QtWidgets.QWidget()
    ui=Ui_Form()
    ui.setupUi(widget)
    widget.setWindowIcon(QIcon('web.png'))#增加icon图标,如果没有图片可以没有这句
    widget.show()
    sys.exit(app.exec_())

8,运行启动,开启了pythonGUI旅程
