下午好，我正在使用 switch 构造，但我不知道如何正确编写 case 运算符之后的其他值。
在DisplayData代码中，在switch构造中，我给字段分配了一个命令号，例如：Vin = cp5.addTextlabel，这样以后通过com口连接时，通过发送这个命令“60”来显示或更改数据",123 在 Vin = cp5.addTextlabel 字段中。
仅适用于 (minutess = cp5.addButton) - 10, (Vin = cp5.addTextlabel) - 60, (inputPULI = cp5.addNumberbox) - 40, (inputNapryzenieKV = cp5.addNumberbox) - 70
主要错误如下（函数“setText（String）”未定义。见截图。
如何为变量修复此问题并正确编写？
图像按钮按钮；
单选按钮 CheckBoxuvum; 文档
复选框 P4；文档
查看图形用户界面文件！
一个任务：
ImageButton（按钮） - 20，目标是通过终端或微控制器发送命令来获得窗口中的图片变化。
P4 = cp5.addCheckBox - 30 CHECK，目标是通过终端或微控制器发送命令来改变窗口中复选框的打开和关闭状态。
CheckBoxuvum = cp5.addRadioButton - 50 +/-，目标是通过终端或微控制器发送命令来改变窗口中复选框的打开和关闭 (+/-) 状态。
在 Displaydata 代码中，我用一个问题对此进行了标记。
将来，我计划通过 com 端口从终端发送命令，以接收这些值的窗口中数据状态的变化。
错误截图：
我将不得不上传所有测试项目文件，以便您进行测试。
