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
|
||
|
|
----------
|
||
|
|
|
||
|
|
:cpp:expr:`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
|
||
|
|
:cpp:expr:`lv_obj_set_tile(tileview, tile_obj, LV_ANIM_ON/OFF)` or
|
||
|
|
:cpp:expr:`lv_obj_set_tile_id(tileviewv, col_id, row_id, LV_ANIM_ON/OFF)`
|
||
|
|
|
||
|
|
