Detailed Description

Naviframe stands for navigation frame. It's a views manager for applications.

A naviframe holds views (or pages) as its items. Those items are organized in a stack, so that new items get pushed on top of the old, and only the topmost view is displayed at one time. Due to the characteristics of a stack, even though you push a new item, previous item is not deleted. Previous item will be shown when you pop new item. The transition between views is animated, depending on the theme applied to the widget.

Naviframe views hold spaces to various elements, which are:

One can use elm_object_item_part_content_set, elm_object_item_part_content_get, elm_object_item_part_content_unset functions to handle the contents. The swallow part name should be one of these:

One can use elm_object_item_part_text_set, elm_object_item_part_text_get to handle the text parts. The swallow part name should be one of these:

Most of those content objects can be passed at the time of an item creation (see elm_naviframe_item_push()).

Naviframe items can have different styles, which affect the transition between views, for example. On the default theme, two of them are supported:

This widget emits the following signals, besides the ones sent from Layout :

All the parts, for content and text, described here will also be reachable by naviframe items direct calls:

What happens is that the topmost item of a naviframe will be the widget's target layout, when accessed directly. Items lying below the top one can be interacted with this way.

Here is an example on its usage:

◆ elm_naviframe_add()

Evas_Object * elm_naviframe_add ( Evas_Object parent)

Add a new Naviframe object to the parent.

Parameters
parentParent object
Returns
New object or NULL, if it cannot be created

const char *  title_label,
Evas_Object prev_btn,
Evas_Object next_btn,
Evas_Object content,
const char *  item_style 
)

)

Control the event enabled when pushing/popping items.

If enabled is true, the contents of the naviframe item will receives events from mouse and keyboard during view changing such as item push/pop.

Warning

Parameters
[in]objThe object.
[in]enabledEvents are received when enabled is true, and ignored otherwise.

◆ elm_naviframe_event_enabled_get()

Eina_Bool elm_naviframe_event_enabled_get ( const Elm_Naviframe *  obj)

Control the event enabled when pushing/popping items.

If enabled is true, the contents of the naviframe item will receives events from mouse and keyboard during view changing such as item push/pop.

Parameters
[in]objThe object.
Returns
Events are received when enabled is true, and ignored otherwise.
