Pyqt5-PySide2
1，下拉框前端和后台关联
py文件
import sys from PySide2.QtCore import QFile from PySide2.QtUiTools import QUiLoader from PySide2.QtWidgets import QApplication class my_form(): def __init__(self): qfile_stats = QFile(r"E:\Work\space\raspberry\ui\power.ui") qfile_stats.open(QFile.ReadOnly) qfile_stats.close() self.ui = QUiLoader().load(qfile_stats) self.ui.comboBox.activated.connect(self.comboActivated) def comboActivated(self, index): if index == -1: print("Clicked on dropdown button") else: print("Selected option", self.ui.comboBox.itemText(index)) if __name__ == '__main__': app = QApplication([]) main = my_form() main.ui.show() app.exec_()
ui文件：使用Qt designer制作的下拉框控件
2，日志实时滚动显示在界面上

3，结果实时显示在界面上
