# 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.
|
||
