13 To create an input device on the :ref:`default_display`:
17     /* Create and set up at least one display before you register any input devices. */
18 …lv_indev_t * indev = lv_indev_create();        /* Create input device connected to Default Display…
23 to the display your input device is "connected to" before making the above calls.
33 report the current state of an input device to LVGL.
41 category.  Here is an example of a simple input-device Read Callback function:
65 Pointer input devices (like a mouse) can have a cursor.
87 Pointer input devices can detect basic gestures.  By default, most Widgets send
124 prevent LVGL sending further input-device-related events.
138 an extension of the pointer input device.  Just set ``data->diff`` to the number of
147 1.  in the input device by the ``indev->rotary_sensitivity`` element (1/256 unit), and
155 For example, if both the indev and widget sensitivity is set to 128 (0.5), the input
242 - Assign the group to an input device: :cpp:expr:`lv_indev_set_group(indev, g)`.
273 In short, the Encoder input devices work like this:
302 When input focus needs to be managed among a set of Widgets (e.g. to capture user
303 input from a keypad or encoder), that set of Widgets is placed in a group which
304 thereafter manages how input focus moves from Widget to Widget.
312 You need to associate an input device with a group.  An input device can
314 than one input device.
325 To associate a group with an input device use :cpp:expr:`lv_indev_set_group(indev, g)`.
397 Don't forget to assign one or more input devices to the default group
506 - ``read_timer`` pointer to the ``lv_timer`` which reads the input device. Its parameters
515 by input devices (independently of their type).  This allows generating
525 To solve this you can write an event driven driver for your input device
527 data instead of directly reading the input device. Setting the
536 need more control over when to read the input device. For example, you
543    /* Update the input device's running mode to LV_INDEV_MODE_EVENT */
548    /* Call this anywhere you want to read the input device */
