# Tile view (lv_tileview)
## Overview
The Tile view is a container object whose elements (called *tiles*) can be arranged in grid form.
A user can navigate between the tiles by swiping.
Any direction of swiping can be disabled on the tiles individually to not allow moving from one tile to another.
If the Tile view is screen sized, the user interface resembles what you may have seen on smartwatches.
## Parts and Styles
The Tile view is built from an [lv_obj](/widgets/obj) container and [lv_obj](/widgets/obj) tiles.
The parts and styles work the same as for [lv_obj](/widgets/obj).
## Usage
### Add a tile
`lv_tileview_add_tile(tileview, row_id, col_id, dir)` creates a new tile on the `row_id`th row and `col_id`th column.
`dir` can be `LV_DIR_LEFT/RIGHT/TOP/BOTTOM/HOR/VER/ALL` or OR-ed values to enable moving to the adjacent tiles into the given direction by swiping.
The returned value is an `lv_obj_t *` on which the content of the tab can be created.
### Change tile
The Tile view can scroll to a tile with `lv_obj_set_tile(tileview, tile_obj, LV_ANIM_ON/OFF)` or `lv_obj_set_tile_id(tileviewv, col_id, row_id, LV_ANIM_ON/OFF);`
## Events
- `LV_EVENT_VALUE_CHANGED` Sent when a new tile loaded by scrolling. `lv_tileview_get_tile_act(tabview)` can be used to get current tile.
## Keys
*Keys* are not handled by the Tile view.
