Typedef Documentation

typedef void(* frame_component_action_cb)(component_h context, const char *action, app_control_h app_control, void *user_data)

Called when another application sends a launch request to the component.

Before calling frame_component_start_cb(), this callback function is called.

Since :: 5.5

Remarks:: After this callback function returns, the handle of the app_control is released. Therefore, if you want to use the handle after returning this callback function, you MUST copy it by using app_control_clone() function.; The action must not be deallocated by the component. The action is managed by the platform and will be released when the app_control action is unregistered.; The context should not be released. The context can be used only in the callback.; The app_control should not be released. The app_control can be used only in the callback. To use outside, make a copy using app_control_clone().

Parameters:

[in]	context	The context of the frame component instance
[in]	action	The name of the app_control action
[in]	app_control	The handle of the app_control
[in]	user_data	The user data passed from component_based_app_add_frame_component() function

See also:: component_register_action(); component_deregister_action()

typedef Evas_Object*(* frame_component_create_cb)(component_h context, void *user_data)

Called when the frame component instance is created.

The returned Evas_Object MUST NOT be released using evas_object_del(). The platform frees the window when the frame component instance is destroyed.

Since :: 5.5

Remarks:: The context should not be released. The context can be used only in the callback.

Parameters:

[in]	context	The context of the frame component instance
