Do you know how to enable different fonts for different WideStudio objects under T-Engine environment?

For example, I want to use "12x24" font for a text field, and "7x14" font for a button.

Here is my /SYS/wsfonts

I have downloaded the two font files: /SYS/12x24.pcf and /SYS/7x14.pcf

However, I am not sure how to configure "Option"->"Environment"->"Fonts" for T-Engine target.

No matter how I choose "Font No." under "Properties" for the two objects "newvlab_002" and "newvbtn_003", only "12x24" font is used for both of them.

How to solve this problem? Thanks!

Best regards,
