How do you hide the keyboard?

How to

What do you want to achieve?

  • When the user presses either the “return key” or the keyboard “checkmark” I want to set the keyboard’s ‘hidden’ flag.

What have you tried so far?

  • Created a function for the keyboard VALUE_CHANGED event. Tried to get the last pressed key with lv_indev_get_key(lv_indev_get_act()); but it just returns 0.
  • I noticed in the lv_event_code_t enum there is an event LV_EVENT_KEY but this is not provided in the SquareLine Studio UI.

Tried this handler added to the keyboard:

lv_obj_add_event_cb(ui_PopupKeyboard, KeyboardPopup_KeyPressed, LV_EVENT_VALUE_CHANGED, NULL);

But this handler produces no meaningful data reflecting the key pressed:

void KeyboardPopup_KeyPressed(lv_event_t *e)
{
    auto key = lv_indev_get_key(lv_indev_get_act());

    Serial.println(key);
    Serial.println(e->code);
    Serial.println(int(e->user_data));
}

In case it useful to anyone, I finally pieced together how to get the keyboard values:

void KeyboardPopup_KeyPressed(lv_event_t *e)
{
    auto key = lv_keyboard_get_selected_btn(ui_PopupKeyboard);
    auto button = lv_keyboard_get_btn_text(ui_PopupKeyboard, key);

    Serial.print(key);
    Serial.print(" | ");
    Serial.println(button);
}

I struggled for about an hour but here’s how I got it to hide. Either defocus from the textarea or press the checkmark on the keyboard. BEWARE: if you are using “focused” for opening the keyboard, the checkmark will close the keyboard but the textarea will remain focused until you defocus. To change that, you can set the show trigger to pressed.
