# Fragment Manager (/examples/others/fragment)



Android-style fragment lifecycle and back-stack navigation via `lv_fragment_manager_t`.

Single fragment inside a container [#single-fragment-inside-a-container]

<LvglExampleBrief>
  Attach an 

  `lv_fragment_manager_t`

   to a full-screen container and replace in one fragment.
</LvglExampleBrief>

A full-screen `lv_obj_create` acts as the root container. An `lv_fragment_manager_t`
is created and wired to the root's `LV_EVENT_DELETE` so
`lv_fragment_manager_delete` runs before the children go away. The custom class
`sample_cls` stores a name string; `lv_fragment_manager_replace` swaps it in and
its `create_obj_cb` builds a label that prints `"Hello, Fragment!"`.

Push and pop fragment stack [#push-and-pop-fragment-stack]

<LvglExampleBrief>
  Build a navigation stack where Push and Pop buttons drive 

  `lv_fragment_manager_push`

  /

  `pop`

  .
</LvglExampleBrief>

A grid layout splits the screen into a content cell and two buttons labelled
"Push" and "Pop". Each stacked fragment tracks its depth and a click counter,
and its `create_obj_cb` builds a column with a depth label, a counter label,
and a `+1` button that updates the counter. "Push" calls
`lv_fragment_manager_push` with the current stack size as the starting depth;
"Pop" calls `lv_fragment_manager_pop`. The root's `LV_EVENT_DELETE` tears the
manager down.
