两个listbox同时显示文本的问题？？？

上位机模拟

如上图所示，上位机模拟创建三个控件，两个listbox和一个scroll，上位机模拟的两个listbox都可以显示文本，单片机端不可以？不知道为什么

这个是OLED吗，方便的话，贴下emWin应用部分的代码，代码没问题的话，有可能是底层移植有些问题，另外就是换成EDIT控件测试下是否有问题。

嗯是OLED，移植参考你那篇 OLED上面移植STemWin5.20应用代码如下，谢谢版主

我现在手头没有OLED模块了，在显示屏上面测试了下，也没问题，你该有其它的控件试试，看看是否正常。

嗯嗯好，我模拟的也没有问题的，就是直接跑到硬件端就不行了
硬件端就只能显示一行的效果，把聚焦只是到哪里相应的就会有显示的，没有聚焦的没有显示

创建两个button没问题可以显示，两个text也可以显示，两个edit貌似是显示不全，只显示了一般我刚刚接触emwin几天可能有些设置（edit）不是很对

尝试找下底层接口函数是否可能出问题，不行的话，就用这种折中的方法显示吧。
