Description

In version 6.0.2, lvgl has lv_obj_set_hidden(), and In the V8.0.1 how to hide an object? I dont want to delete objects.

By the way, how to hide the textarea cursor . The style set in 8.0.1 is different from 6.0.2

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

Simply add or clear the flag as follows, where obj is the object you want to hide or display:

lv_obj_add_flag(obj, LV_OBJ_FLAG_HIDDEN);

lv_obj_clear_flag(obj, LV_OBJ_FLAG_HIDDEN);

Use method: cursor_blink_anim_cb(void * my_text_area_obj, int32_t show)
show = 0 ā†’ show cursor

Thank you for your response. But this is an internal function and I prefer my code to be clean.
I finally did it with this code

lv_obj_t* spinBox = lv_spinbox_create(scr);

static lv_style_t style1;
lv_style_init(&style1);
lv_style_set_bg_opa(&style1, LV_OPA_TRANSP);
lv_style_set_text_opa(&style1, LV_OPA_TRANSP);
lv_obj_add_style(spinBox, &style1, LV_PART_CURSOR);

static lv_style_t style2;
lv_style_init(&style2);
lv_style_set_bg_opa(&style2, LV_OPA_100);
lv_style_set_text_opa(&style2, LV_OPA_100);
lv_obj_add_style(spinBox, &style2, LV_PART_CURSOR | LV_STATE_FOCUS_KEY);
lv_obj_add_style(spinBox, &style2, LV_PART_CURSOR | LV_STATE_FOCUSED);
