Description
I want to do some cooperation between textarea and keyboard, such as when click textarea, it shows keyboard, then when I clicked the LV_SYMBOL_KEYBOARD hide the keyboard and the textarea cursor. I found some problems in my code.
1、how to hide textarea cursor? It’s not so convenient compare with V6.0.2
2、If I simply create a keyboard, then I clicked the LV_SYMBOL_KEYBOARD, it can’t hide the keyboard.
3、In my code, ta_event_cb. When I try to debug my code, once I clicked the textarea, It seems to run it in ta_event_cb again and again, but the lv_event_code_t code is different everytime.
4、If I add textarea through LV_EVENT_CLOSE not through LV_EVENT_ALL，then I found if I click one textarea, the keyboard will close, then I clicked this textarea again, it will not run into ta_event_cb again, when I click another textaren it run it in ta_event_cb again.

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:
static void ta_event_cb(lv_event_t * e)
{
lv_event_code_t code = lv_event_get_code(e);
lv_obj_t * ta = lv_event_get_target(e);
if(code == LV_EVENT_CLICKED || code == LV_EVENT_FOCUSED) {
/*Focus on the clicked text area*/
if(g_keyboard != NULL)
{
lv_obj_clear_flag(g_keyboard, LV_OBJ_FLAG_HIDDEN);
lv_keyboard_set_textarea(g_keyboard, ta);
}
}
else if(code == LV_EVENT_READY) {
LV_LOG_USER("Ready, current text: %s", lv_textarea_get_text(ta));
}
}
static void KeyboardEventCB(lv_event_t* event)
{
// lv_keyboard_def_event_cb(event);
//
lv_event_code_t code = lv_event_get_code(event);
//
// lv_obj_t* ta_of_kb = lv_keyboard_get_textarea(g_keyboard);
//
if(code == LV_EVENT_CANCEL)
{
// lv_textarea_t * ta = (lv_textarea_t *)ta_of_kb;
// ta->cursor.show = 0;
lv_obj_add_flag(g_keyboard, LV_OBJ_FLAG_HIDDEN);
}
}
void CreateKeyboard(lv_obj_t* parent, lv_coord_t w, lv_coord_t h)
{
g_keyboard = lv_keyboard_create(parent);
lv_obj_set_size(g_keyboard, w, h);
lv_obj_align_to(g_keyboard, parent, LV_ALIGN_BOTTOM_RIGHT, 0, 0);
// lv_obj_add_event_cb(g_keyboard, KeyboardEventCB, LV_EVENT_CANCEL, NULL);
// lv_obj_add_flag(g_keyboard, LV_OBJ_FLAG_HIDDEN);
}
int main()
{
CreateKeyboard(lv_scr_act(), 940, 150);
lv_obj_clear_flag(g_keyboard, LV_OBJ_FLAG_HIDDEN);
lv_obj_t * text_ta = lv_textarea_create(lv_scr_act());
lv_textarea_set_one_line(text_ta, true);
lv_textarea_set_password_mode(text_ta, false);
lv_obj_set_width(text_ta, lv_pct(40));
lv_obj_add_event_cb(text_ta, ta_event_cb, LV_EVENT_ALL, NULL);
lv_obj_align_to(text_ta, NULL, LV_ALIGN_TOP_LEFT, 0, 60);
lv_obj_t * text_ta1 = lv_textarea_create(lv_scr_act());
lv_textarea_set_one_line(text_ta1, true);
lv_textarea_set_password_mode(text_ta1, false);
lv_obj_set_width(text_ta1, lv_pct(40));
lv_obj_add_event_cb(text_ta1, ta_event_cb, LV_EVENT_ALL, NULL);
lv_obj_align_to(text_ta1, NULL, LV_ALIGN_TOP_RIGHT, 0, 60);
}
