Hi List,
Since we need to limit the entered text length, we create a patch
the allow etk_entry to to that
Adding two functions:
void etk_entry_text_set(Etk_Entry *entry, const char *text)
int etk_entry_text_limit_get(Etk_Entry *entry)
let programmer's to limit the max input length of etk_entry.
if set to 0 that means no limited.
default is 0
Cheers,
Tick
