Detailed Description

A hoversel is a button that pops up a list of items (automatically choosing the direction to display) that have a label and, optionally, an icon to select from. It is a convenience widget to avoid the need to do all the piecing together yourself. It is intended for a small number of items in the hoversel menu (no more than 8), though is capable of many more.

This widget inherits from the Button one, so that all the functions acting on it also work for hoversel objects.

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

•   'clicked' - the user clicked the hoversel button and popped up the sel

•   'selected' - an item in the hoversel list is selected. event_info is the selected item

•   'dismissed' - the hover is dismissed

•   'expanded' - This is called on clicking hoversel and elm_hoversel_hover_begin().

•   'language,changed' - the program's language changed (since 1.9)

•   'item,focused' - When the hoversel item has received focus. (since 1.10)

•   'item,unfocused' - When the hoversel item has lost focus. (since 1.10)

Default content parts of the hoversel widget that you can use for are:
•
Default text parts of the hoversel widget that you can use for are:
•
Supported elm_object common APIs.
•   elm_object_disabled_set
•   elm_object_disabled_get
•   elm_object_part_text_set
•   elm_object_part_text_get
•   elm_object_part_content_set
•   elm_object_part_content_unset
Supported elm_object_item common APIs.
•   elm_object_item_del
•   elm_object_item_part_text_get
•   elm_object_item_signal_emit - this works only when the item is created.
•   elm_object_item_style_set - this works only when the item is created.
•   elm_object_item_style_get - this works only when the item is created.
•   elm_object_item_focus_set - this works only when the item is created.
•   elm_object_item_focus_get - this works only when the item is created.

Add a new Hoversel object.
Parameters
    parent The parent object
Returns
    The new object or NULL if it cannot be created
References EINA_SAFETY_ON_NULL_RETURN_VAL.

  EOAPI void elm_obj_hoversel_horizontal_set (Eo * obj, Eina_Bool horizontal)
Control if the hoversel should expand horizontally.
Note
    The initial button will display horizontally regradless of this setting.
Parameters

    obj The object.
Returns
    If true, the hover will expand horizontally to the right.

  EOAPI void elm_obj_hoversel_hover_parent_set (Eo * obj, Efl_Canvas_Object * parent)
Control the hover parent. Sets the hover parent object, the area that will be darkened when the hoversel is clicked. Should probably be the window that the hoversel is in.
Parameters
    obj The object.
    parent The parent to use

  EOAPI Efl_Canvas_Object* elm_obj_hoversel_hover_parent_get (const Eo * obj)
Control the hover parent. Sets the hover parent object, the area that will be darkened when the hoversel is clicked. Should probably be the window that the hoversel is in.
Parameters
    obj The object.
Returns
    The parent to use

  EOAPI Eina_Bool elm_obj_hoversel_expanded_get (const Eo * obj)
Returns whether the hoversel is expanded.
Parameters
    obj The object.
Returns
    true if the hoversel is expanded or false otherwise

  EOAPI const Eina_List* elm_obj_hoversel_items_get (const Eo * obj)
Get the list of items within the given hoversel.
Parameters
    obj The object.
Returns
    List of items

  EOAPI void elm_obj_hoversel_auto_update_set (Eo * obj, Eina_Bool auto_update)
Update icon and text of hoversel same to those of selected item automatically.
Parameters
    obj The object.
    auto_update true if hoversel is updated automatically or false otherwise

  EOAPI Eina_Bool elm_obj_hoversel_auto_update_get (const Eo * obj)
Update icon and text of hoversel same to those of selected item automatically.
Parameters
    obj The object.
Returns
    true if hoversel is updated automatically or false otherwise

  EOAPI void elm_obj_hoversel_clear (Eo * obj)
This will remove all the children items from the hoversel. Warning Should not be called while the hoversel is active; use elm_obj_hoversel_expanded_get to check first.
Parameters
    obj The object.

  EOAPI Elm_Widget_Item* elm_obj_hoversel_item_add (Eo * obj, const char * label, const char * icon_file, Elm_Icon_Type icon_type, Evas_Smart_Cb func, const void * data)
Add an item to the hoversel button. This adds an item to the hoversel to show when it is clicked. Note: if you need to use an icon from an edje file then use Elm.Hoversel.Item.icon.set right after this function, and set icon_file to null here.
Parameters
    obj The object.
    label The text label to use for the item (NULL if not desired)
    icon_file An image file path on disk to use for the icon or standard icon name (NULL if not desired)
