A diskselector is a kind of list widget. It scrolls horizontally, and can contain label and icon objects. Three items are displayed with the selected one in the middle.
It can act like a circular list with round mode and labels can be reduced for a defined length for side items.
This widget implements the elm-scrollable-interface interface, so that all (non-deprecated) functions for the base Scroller widget also work for diskselectors.
Some calls on the diskselector's API are marked as deprecated, as they just wrap the scrollable widgets counterpart functions. Use the ones we point you to, for each case of deprecation here, instead – eventually the deprecated ones will be discarded (next major release).
This widget emits the following signals, besides the ones sent from Layout:
"selected"
- when item is selected, i.e. scroller stops. "clicked"
- This is called when a user clicks an item (since 1.8) "scroll,anim,start"
- scrolling animation has started "scroll,anim,stop"
- scrolling animation has stopped "scroll,drag,start"
- dragging the diskselector has started "scroll,drag,stop"
- dragging the diskselector has stopped "focused"
- When the diskselector has received focus. (since 1.8) "unfocused"
- When the diskselector has lost focus. (since 1.8) "language,changed"
- the program's language changed (since 1.9)Available styles for it:
"default"

List of examples:
EINA_DEPRECATED void elm_diskselector_bounce_set | ( | Evas_Object * | obj, |
Eina_Bool | h_bounce, | ||
Eina_Bool | v_bounce | ||
) |
Set bouncing behaviour when the scrolled content reaches an edge.
Tell the internal scroller object whether it should bounce or not when it reaches the respective edges for each axis.
obj | The diskselector object. |
h_bounce | Whether to bounce or not in the horizontal axis. |
v_bounce | Whether to bounce or not in the vertical axis. |
EINA_DEPRECATED void elm_diskselector_bounce_get | ( | const Evas_Object * | obj, |
Eina_Bool * | h_bounce, | ||
Eina_Bool * | v_bounce | ||
) |
Get the bouncing behaviour of the internal scroller.
Get whether the internal scroller should bounce when the edge of each axis is reached scrolling.
obj | The diskselector object. |
h_bounce | Pointer to store the bounce state of the horizontal axis. |
v_bounce | Pointer to store the bounce state of the vertical axis. |
EINA_DEPRECATED void elm_diskselector_scroller_policy_get | ( | const Evas_Object * | obj, |
Elm_Scroller_Policy * | policy_h, | ||
Elm_Scroller_Policy * | policy_v | ||
) |
Get the scrollbar policy.
obj | The diskselector object. |
policy_h | Pointer to store horizontal scrollbar policy. |
policy_v | Pointer to store vertical scrollbar policy. |
EINA_DEPRECATED void elm_diskselector_scroller_policy_set | ( | Evas_Object * | obj, |
Elm_Scroller_Policy | policy_h, | ||
Elm_Scroller_Policy | policy_v | ||
) |
Set the scrollbar policy.
obj | The diskselector object. |
policy_h | Horizontal scrollbar policy. |
policy_v | Vertical scrollbar policy. |
This sets the scrollbar visibility policy for the given scroller. #ELM_SCROLLER_POLICY_AUTO means the scrollbar is made visible if it is needed, and otherwise kept hidden. ELM_SCROLLER_POLICY_ON turns it on all the time, and ELM_SCROLLER_POLICY_OFF always keeps it off. This applies respectively for the horizontal and vertical scrollbars.
The both are disabled by default, i.e., are set to ELM_SCROLLER_POLICY_OFF.
References ELM_SCROLLER_POLICY_LAST.
EOAPI void elm_obj_diskselector_side_text_max_length_set | ( | Eo * | obj, |
int | len | ||
) |
Set the side labels max length.
Length is the number of characters of items' label that will be visible when it's set on side positions. It will just crop the string after defined size. E.g.:
An item with label "January" would be displayed on side position as "Jan" if max length is set to 3, or "Janu", if this property is set to 4.
When it's selected, the entire label will be displayed, except for width restrictions. In this case label will be cropped and "..." will be concatenated.
Default side label max length is 3.
This property will be applied over all items, included before or later this function call.
[in] | len | The max length defined for side labels. |

Enable or disable round mode.
Disabled by default. If round mode is enabled the items list will work like a circular list, so when the user reaches the last item, the first one will popup.

[in] | enabled | true to enable round mode or false to disable it. |

EOAPI void elm_obj_diskselector_display_item_num_set | ( | Eo * | obj, |
int | num | ||
) |
Set the number of items to be displayed.
Default value is 3, and also it's the minimum. If num
is less than 3, it will be set to 3.
Also, it can be set on theme, using data item display_item_num
on group "elm/diskselector/item/X", where X is style set.

EOAPI Elm_Widget_Item* elm_obj_diskselector_first_item_get | ( | const Eo * | obj | ) |
Get the first item of the diskselector.
The list of items follows append order. So it will return the first item appended to the widget that wasn't deleted.
See also elm_obj_diskselector_item_append, elm_obj_diskselector_items_get.

EOAPI Elm_Widget_Item* elm_obj_diskselector_last_item_get | ( | const Eo * | obj | ) |
Get the last item of the diskselector.
The list of items follows append order. So it will return last first item appended to the widget that wasn't deleted.

if none. Referenced by elm_diskselector_last_item_get().
EOAPI Elm_Widget_Item* elm_obj_diskselector_selected_item_get | ( | const Eo * | obj | ) |
Get the selected item.
The selected item can be unselected with function elm_obj_diskselector_selected_item_set, and the first item of diskselector will be selected.
The selected item always will be centered on diskselector, with full label displayed, i.e., max length set to side labels won't apply on the selected item. More details on elm_obj_diskselector_side_text_max_length_set.
Referenced by elm_diskselector_selected_item_get().
EOAPI Elm_Widget_Item* elm_obj_diskselector_item_append | ( | Eo * | obj, |
const char * | label, | ||
Efl_Canvas_Object * | icon, | ||
Evas_Smart_Cb | func, | ||
const void * | data | ||
) |
Appends a new item to the diskselector object.
A new item will be created and appended to the diskselector, i.e., will be set as last item. Also, if there is no selected item, it will be selected. This will always happens for the first appended item.
If no icon is set, label will be centered on item position, otherwise the icon will be placed at left of the label, that will be shifted to the right.
Items created with this method can be deleted with elm_object_item_del.
Associated data
can be properly freed when item is deleted if a callback function is set with elm_object_item_del_cb_set.
If a function is passed as argument, it will be called every time this item is selected, i.e., the user stops the diskselector with this item on center position. If such function isn't needed, just passing null
as func
is enough. The same should be done for data
.
