使用PyQt5动态导入ui文件

导库

from PyQt5.uic import *

核心代码

self.ui = loadUi(r'xxxx文件路径xxxx', self)

简单代码实例

import sys
from PyQt5.uic import *
from PyQt5.QtWidgets import *


class firstWindow(QMainWindow):
    def __init__(self):
        super(firstWindow, self).__init__()
        self.ui = loadUi(r'E:\pycharm_Projects\test\ui\UiDesigner\firstEasyUi.ui', self)
        self.ui.pushButton.clicked.connect(self.clickToPrint)

    def clickToPrint(self):
        info = self.ui.textEdit.toPlainText()
        print(info)


if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWindow = firstWindow()
    mainWindow.show()
    sys.exit(app.exec_())
