Porting from 5.3 to 7.4


I’m trying to port our application from lvgl5.3 to lvgl7.4. I would like to use our already defined styles, defined starting from the build-in one (E.g. lv_style_pretty), but, if I’m reading well, in 7.4 these build-in styles doesn’t exists anymore,
Is this correct ?

What MCU/Processor/Board and compiler are you using?

Custum board with ARRIA10 and VxWorks RTOS

What LVGL version are you using?
Porting from lvgl5.3 to 7.4

What do you want to achieve?
Use already defined styles

What have you tried so far?

Code to reproduce
lv_style_copy(&font_test_style_pretty, &lv_style_pretty);
receive an error (lv_style_pretty doesn’t exists)



That’s correct; the built-in styles no longer exist and have been replaced by a newer theme.

If you need the old styles, you can try my style compatibility module. The README has instructions on how to use it.
