lv_indev.h

lv_indev_set_type

Set the type of an input device

void lv_indev_set_type(lv_indev_t *indev, lv_indev_type_t indev_type)

lv_indev_set_read_cb

Set a callback function to read input device data to the indev

void lv_indev_set_read_cb(lv_indev_t *indev, lv_indev_read_cb_t read_cb)

lv_indev_set_user_data

Set user data to the indev

void lv_indev_set_user_data(lv_indev_t *indev, void *user_data)

lv_indev_set_driver_data

Set driver data to the indev

void lv_indev_set_driver_data(lv_indev_t *indev, void *driver_data)

lv_indev_set_display

Assign a display to the indev

void lv_indev_set_display(lv_indev_t *indev, struct _lv_display_t *disp)

lv_indev_set_long_press_time

Set long press time to indev

void lv_indev_set_long_press_time(lv_indev_t *indev, uint16_t long_press_time)

lv_indev_set_long_press_repeat_time

Set long press repeat time to indev

void lv_indev_set_long_press_repeat_time(lv_indev_t *indev, uint16_t long_press_repeat_time)

lv_indev_set_scroll_limit

Set scroll limit to the input device

void lv_indev_set_scroll_limit(lv_indev_t *indev, uint8_t scroll_limit)

lv_indev_set_scroll_throw

Set scroll throw slow-down to the indev. Greater value means faster slow-down

void lv_indev_set_scroll_throw(lv_indev_t *indev, uint8_t scroll_throw)

lv_indev_set_gesture_min_velocity

Set the minimum velocity threshold for gesture detection. The difference between consecutive points must exceed this value (in pixels) for the movement to be considered fast enough to trigger a gesture.

void lv_indev_set_gesture_min_velocity(lv_indev_t *indev, uint8_t min_velocity)

lv_indev_set_gesture_min_distance

Set the minimum distance threshold for gesture detection. The total distance from the first point to the current point must exceed this value (in pixels) for the movement to be considered large enough to trigger a gesture.

void lv_indev_set_gesture_min_distance(lv_indev_t *indev, uint8_t min_distance)

lv_indev_set_cursor

Set a cursor for a pointer input device (for LV_INPUT_TYPE_POINTER and LV_INPUT_TYPE_BUTTON)

void lv_indev_set_cursor(lv_indev_t *indev, lv_obj_t *cur_obj)

lv_indev_set_group

Set a destination group for a keypad input device (for LV_INDEV_TYPE_KEYPAD)

void lv_indev_set_group(lv_indev_t *indev, lv_group_t *group)

lv_indev_set_button_points

Set the an array of points for LV_INDEV_TYPE_BUTTON. These points will be assigned to the buttons to press a specific point on the screen

void lv_indev_set_button_points(lv_indev_t *indev, const lv_point_t points[])

lv_indev_set_mode

Set the input device's event model: event-driven mode or timer mode.

void lv_indev_set_mode(lv_indev_t *indev, lv_indev_mode_t mode)

lv_indev_set_key_remap_cb

Set key remapping callback (LV_INDEV_TYPE_KEYPAD)

void lv_indev_set_key_remap_cb(lv_indev_t *indev, lv_indev_key_remap_cb_t remap_cb)

lv_indev_set_external_data

Attaches external user data and destructor callback to an indev.

Associates custom user data with an LVGL indev and specifies a destructor function that will be automatically invoked when the indev is deleted to properly clean up the associated resources.

void lv_indev_set_external_data(lv_indev_t *indev, void *data, void(*free_cb)(void *data))
