Hello @SLuo.2 ,

The implementation of ellipsis characters in TouchGFX could be quite tricky to understand.

Let us check if you included everything to make it work :

In Screen1View.cpp, did you call the setWideTextAction() function ? It will enable you to automatically wrap long text lines. You can find example of that in the documentation.
In your TouchGFXDesigner screenshot, I noticed that you wanted to print three-dots "..." character. Unfortunately, only one character is allowed for ellipsis. But, if you really want to display those three dots. you can write "0x2026" in this field, which is the hex code for those symbols.

Let me know if that helped you,

oh,Thanks!

Is because I ignored the setWideTextAction() function.
