Typedef Documentation

typedef bool(* ui_application_event_cb)(void *user_data, void *event_info)

The ui_application event callback function signature.

Since :
3.0
Parameters:
[in]user_dataThe user data to be passed to the given event_callback functions
[in]event_infoEvent Information data (It can casts to app_control_h in app_control())
Returns:
This is reserved

Enumeration Type Documentation

enum ui_application_event_type_e

Enumeration for ui_application event type.

Remarks:
PRE events are designed for overriding the default behavior of the events. Normally, ui_application triggers ui_viewmgr actions on those event time. To ignore them, you can use PRE event callbacks.
Since :
3.0
Enumerator:
UI_APPLICATION_EVENT_CREATE 

App create

UI_APPLICATION_EVENT_TERMINATE 

App terminate

UI_APPLICATION_EVENT_PAUSE 

App pause

UI_APPLICATION_EVENT_RESUME
