PyQt5 主窗口操作多个子窗口实现

实现思路

     1.pyqt5 designer  生成ui --py 修改文件

     2.ui  -- py ,主py 直接操作

     3.  main py 操作 ui 继承类py, ui py

优选方案3.

示例

from  main_win import Ui_MainWindow
from  about_us import Ui_Form
# 导入uitestPyQt5.ui转换为uitestPyQt5.py中的类
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QDialog

class RunMainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self):
        super(RunMainWindow, self).__init__()
        super().setupUi(self);
    def colse(self):
        self.close()


class Child(QMainWindow, Ui_Form):
    def __init__(self):
        super(Child, self).__init__()
        self.setupUi(self)

    def open(self):
        self.show()
if __name__ == '__main__':
    app = QApplication(sys.argv)  # 初始化app
    munMainWindow = RunMainWindow()
    cd = Child()
    munMainWindow.show()  # 显示窗口
    munMainWindow.btnSubmit.clicked.connect(cd.open)
    munMainWindow.closeWinMain.clicked.connect(munMainWindow.colse)
    sys.exit(app.exec_())
