调用QListWidget分页多选控件的容器

  1. class ExampleWidget(QtWidgets.QWidget):
  2.     def __init__(self):
  3.         super().__init__()
  4.         self.init_ui()
  5.     def init_ui(self):
  6.         self.list_widget = MultiChoicePageListWidget()
  7.         self.list_widget.sinout_signal.connect(self.list_widget_sinout_emit)
  8.         layout = QtWidgets.QVBoxLayout()
  9.         layout.addWidget(self.list_widget)
  10.         self.setLayout(layout)
  11.         pass
  12.     def set_data(self,data:Dict[str,Any]):
  13.         self.list_widget.set_data(data)
  14.         pass
  15.     def list_widget_sinout_emit(self,data:List[str]):
  16.         print(data)
  17.         pass

使用：

  1. if __name__ == '__main__':
  2.     whole_left = ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31','32','33','34','35','36','37','38','39','40','41','42','43','44','45','46','47','48','49','50','51','52','53','54','55','56','57','58','59','60','61','62','63','64','65','66']
  3.     whole_right = ['1','2','3','4','5']
  4.     data = {
  5.        'whole_left':whole_left,
  6.         'whole_right':whole_right
  7.     }
  9.     QtCore.QCoreApplication.setAttribute(QtCore.Qt.HighDpiScaleFactorRoundingPolicy.PassThrough)
  10.     app = QtWidgets.QApplication(sys.argv)
  12.     temp_win = ExampleWidget()
  13.     temp_win.set_data(data)
  14.     temp_win.show()
  15.     app.exec()
  16.     pass

运行：

清空右侧，并选中左侧所有包含“1”的选项：

 点击“清空”，清空右侧列表；在左侧模糊查询中输入1，点击“查询”按钮；接下来选中左侧包含“1”的内容，添加到右侧

 点击“确认提交”，后台接收到选中的结果
