使用designer 画好ui，注意选择dialog对话框
然后将ui文件转换成py
目标和源文件换成你自己的
pyuic5 -o qt_hgbp.py htbp_autotest.ui
主窗口调用子窗口
方法一：常规调用,
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QDialog
## 引入主窗口ui转py文件
from dust.mainWindow import *
## 引入子串口ui转py文件
from dust.childWindow import *
if __name__ == '__main__':
app = QApplication(sys.argv)
#实例化主窗口
main = QMainWindow()
main_ui = Ui_MainWindow()
main_ui.setupUi(main )
#实例化子窗口
child = QDialog() ##基于dailog对象
child_ui = Ui_Dialog()
child_ui.setupUi(child)
#按钮绑定事件
btn = main_ui.pushButton
btn.clicked.connect( child.show )
#显示
main.show()
sys.exit(app.exec_())
以上的子窗口存在一个问题，那就是子串口无法自定义隐藏窗口
以下是优化代码
