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
2,Tools -》 External Tools -》点击“+”号
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。
四、使用Qt Designer
1,完成以上步骤之后,点击 Tools -》External Tools -》Qt Designer 启动我们的Qt Designer。
2,启动后选择:Widget,建立空白的窗口,点击 Create,其他默认就行
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
9,源代码:
