Detailed Description

Interface between pages of the Prefs widget and the real widgets implementing them.

This structure defines the interface between the Prefs widget's pages and Elementary widgets implementing them.

It is mandatory that the following functions be implemented, at least, for a page widget:

• Elm_Prefs_Page_Iface::add
• Elm_Prefs_Page_Iface::item_pack
• Elm_Prefs_Page_Iface::item_unpack
• Elm_Prefs_Page_Iface::item_pack_before
• #Elm_Prefs_Page_Iface::item_pack_after

Note

For regular, non-page prefs items, refer to #Elm_Prefs_Item_Iface.

Since

1.8

Field Documentation

abi_version

unsigned int _Elm_Prefs_Page_Iface::abi_version

always use:

• #ELM_PREFS_PAGE_IFACE_ABI_VERSION to declare.
• elm_prefs_widget_iface_abi_version_get() to check.

Referenced by elm_prefs_page_iface_register().

add

Evas_Object *(* _Elm_Prefs_Page_Iface::add) (const Elm_Prefs_Page_Iface *iface, Evas_Object *prefs)

Function to instantiate the page widget.

It must return the widget handle, which should be the obj argument on the functions which follow. That object argument, by the way, should always have their respective #Elm_Prefs_Page_Node handle accessible via a "prefs_page" Evas object data value. The return value of the following functions should be EINA_TRUE, on success or EINA_FALSE, otherwise.
