How-to

Description

I want to manage the calendar by sending an event LV_EVENT_KEY

What MCU/Processor/Board and compiler are you using?

What LVGL version are you using?

8.3

What do you want to achieve?

What have you tried so far?

Code to reproduce

PanelEditParam.Calendar = lv_calendar_create(PanelEditParam.MainPanel);
PanelEditParam.Calendar_header = lv_calendar_header_dropdown_create(PanelEditParam.Calendar);
lv_obj_set_width(PanelEditParam.Calendar, 230);
lv_obj_set_height(PanelEditParam.Calendar, 240);
lv_obj_set_align(PanelEditParam.Calendar, LV_ALIGN_CENTER);
PanelEditParam.group = lv_group_create();
lv_group_add_obj(PanelEditParam.group, PanelEditParam.Calendar);

then i send the key code to the group

int key = LV_KEY_DOWN;
lv_group_send_data(PanelEditParam.group, &key);
key = LV_KEY_DOWN;
lv_group_send_data(PanelEditParam.group, &key);

but the calendar does not change the selected day

Please help me solve this problem.

Screenshot and/or video

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

In general, can the calendar be controlled by the LV_EVENT_KEY event?
I can’t do anything

as you can see
c – a character (use LV_KEY_.. to navigate)
so you should use key code, not it pointer.
lv_group_send_data(PanelEditParam.group, key);

Yes, I fixed this error, but nothing changed.
