VSCode + PYQT5 搭建图形化界面

1，安装依赖

pip install -i https://mirrors.aliyun.com/pypi/simple/ PyQt5
 
pip install -i https://mirrors.aliyun.com/pypi/simple/ PyQt5-tools

2，找到designer 绘制ui界面程序

例：windows

C:\Users\Administrator\AppData\Local\Programs\Python\Python37\Lib\site-packages\pyqt5_tools\Qt\bin\designer.exe

绘制如下：

完事后保存 haha.ui

3，VSCode转化.ui文件为.py文件（安装PYQT Integration扩展）

右击haha.ui --- PYQT:Compile Form 会生成 Ui_haha.py 文件

然后调用UI类并运行py

import sys
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QApplication, QMainWindow
 
class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(190, 200, 311, 81))
        self.pushButton.setObjectName("pushButton")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 23))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
 
        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)
 
    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "你好"))
 
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

结果如下：
