Select the text using button

Hello everyone,
I’m using LVGL for my project. I have buttons and a text area. I want to use these button to select the text in the text area instead of mouse. My purpose is I click the Enter button and then the text inside the textarea select. After that, the user can edit the text inside it. I read the API but I can’t find the function that I want. Can anybody give me some suggestions?
I’m looking forward to seeing your repy as soon as possible.
Best regards,

The textarea is made up of label and page, so you can use the label API in the textarea,

First you need to uselv_obj_t * lv_textarea_get_label(const lv_obj_t * ta)To get the label object frome the textarea, and then use lv_label_set_text_sel_startlv_obj_t *label ,uint32_t index )And lv_label_set_text_sel_endlv_obj_t *label ,uint32_t index )To select the text

Tks, I got it. Tks a lot
