isn't that just formatting of the text vs plain txt?
@fbiego any chance you can clarify this?

It's what @techielew said above
but the format are handled by styles, not objects specifically, plus the the parameter to pass doesnt let it pass styles or format
kinda unclear what the explaination
well the one sets formatted text and the other sets text with the default format
Assume you had a label that could go
italic when processing and normal when done.
just did some trial and error
turns out
the "formatted" string wasn't the one i was thinking like itallic, bold etc...
it was related to passing variables similar to printf
Yes
So basically one for concatenation and one for whole strings
Makes sense
lv_label_set_text makes the label like a string literal(aka we cant change it in runtime as it goes to the read-only memory part)
while the other is argument based string(aka we can change it dynamically/runtime)
