All UI objects passed to AddControl() will be deleted automatically when the app terminates. If you try to deallocate them manually, you will crash the app.

If the UI object not passe to AddControl(), like KeyPad object, then you need to deallocate it manually.

Hi Victor,

According to

https://developer.tizen.org/dev-guide/2.2.1/org.tizen.native.appprogramming/html/guide/ui/containers.htm

"Since all child controls are automatically removed and deleted when the parent container is deleted, you do not have to explicitly remove child controls by yourself. Furthermore, if you delete a child control without removing it from its parent container, it causes unhandled exceptions when the parent tries to remove the deleted control."

Hi Victor,

Regarding your 1^st question about Construct() method.

1. This is safe.
2. Don’t worry about that. The Construct() will copy object if it’s needed.
3. Yes, you can pass object created by new operator. In this case you should release it later because the Construct() knows nothing about where/how the object was created.

Thanks! To sum up:

1. Construct() method copies objects and for this reason we can use temporary objects, as in my example. Also we can use heap-allocated objects, but should delete them manually, for example after passing to Construct() method.
2. AddControl() uses only heap-allocated objects and should automatically delete these objects. After passing the pointer to AddControl() don't need worry about it.
