## Detailed Description

A spinner is a widget which allows the user to increase or decrease numeric values using arrow buttons, or edit values directly, clicking over it and typing the new value.

By default the spinner will not wrap and has a label of "%.0f" (just showing the integer value of the double).

A spinner has a label that is formatted with floating point values and thus accepts a printf-style format string, like “%1.2f units”.

It also allows specific values to be replaced by pre-defined labels.

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

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

- `"changed"` - Whenever the spinner value is changed.
- `"delay,changed"` - A short time after the value is changed by the user. This will be called only when the user stops dragging for a very short period or when they release their finger/mouse, so it avoids possibly expensive reactions to the value change.
- `"language,changed"` - the program's language changed
- `"focused"` - When the spinner has received focus. (since 1.8)
- `"unfocused"` - When the spinner has lost focus. (since 1.8)
- `"spinner,drag,start"` - When dragging has started. (since 1.8)
- `"spinner,drag,stop"` - When dragging has stopped. (since 1.8)

Available styles for it:

- `"default"`;
- `"vertical"`: up/down buttons at the right side and text left aligned.

Supported elm_object common APIs.

- elm_object_signal_emit
- elm_object_signal_callback_add
- elm_object_signal_callback_del
- elm_object_disabled_set
- elm_object_disabled_get

## Function Documentation

EOAPI double elm_obj_spinner_base_get | ( | void |  | ) |

Get the base for rounding.

Returns
  The base rounding value

This returns the base for rounding.

See also
  elm_spinner_round_set() too.
  elm_spinner_base_set() too.

Referenced by elm_spinner_base_get().

EOAPI void elm_obj_spinner_base_set | ( | double | base | ) |

Set the base for rounding.

Rounding works as follows:

rounded_val = base + (double)(((value - base) / round) * round)

Where rounded_val, value and base are doubles, and round is an integer.

This means that things will be rounded to increments (or decrements) of "round" starting from value `base`. The default base for rounding is 0.

Example: round = 3, base = 2 Values: ..., -2, 0, 2, 5, 8, 11, 14, ...

Example: round = 2, base = 5.5 Values: ..., -0.5, 1.5, 3.5, 5.5, 7.5, 9.5, 11.5, ...

  elm_spinner_round_get()

Parameters

  [in] | base | The base value

Referenced by elm_spinner_base_set().

EOAPI Eina_Bool elm_obj_spinner_editable_get | ( | void |  | ) |

Get whether the spinner can be directly edited by the user or not.

Returns
  `EINA_TRUE` means edition is enabled. `EINA_FALSE` indicates it's disabled. If `obj` is `NULL`, `EINA_FALSE` is returned.

See also
  elm_spinner_editable_set() for details.

Referenced by elm_spinner_editable_get().

EOAPI void elm_obj_spinner_editable_set | ( | Eina_Bool | editable | ) |

Set whether the spinner can be directly edited by the user or not.

Spinner objects can have edition disabled, in which state they will be changed only by arrows. Useful for contexts where you don't want your users to interact with it writing the value. Specially when using special values, the user can see real value instead of special label on edition.

It's enabled by default.

See also
  elm_spinner_editable_get()

Parameters

  [in] | editable | `EINA_TRUE` to allow users to edit it or `EINA_FALSE` to don't allow users to edit it directly.

Referenced by elm_spinner_editable_set().

EOAPI double elm_obj_spinner_interval_get | ( | void |  | ) |

Get the interval on time updates for an user mouse button hold on spinner widgets' arrows.

Returns
  The (first) interval value, in seconds, set on it.

See also
  elm_spinner_interval_set() for more details.

Referenced by elm_spinner_interval_get().

EOAPI void elm_obj_spinner_interval_set | ( | double | interval | ) |

Set the interval on time updates for an user mouse button hold on spinner widgets' arrows.

This interval value is decreased while the user holds the mouse pointer either incrementing or decrementing spinner's value.

This helps the user to get to a given value distant from the current one easier/faster, as it will start to change quicker and quicker on mouse button holds.

The calculation for the next change interval value, starting from the one set with this call, is the previous interval divided by `1.05`, so it decreases a little bit.

The default starting interval value for automatic changes is `0.85` seconds.

See also
  elm_spinner_interval_get()

Parameters

  [in] | interval | The (first) interval value in seconds.

Referenced by elm_spinner_interval_set().

EOAPI const char* elm_obj_spinner_label_format_get | ( | void |  | ) |

Get the label format of the spinner.

Returns
  The text label format string in UTF-8.

See also
  elm_spinner_label_format_set() for details.

Referenced by elm_spinner_label_format_get().

EOAPI void elm_obj_spinner_label_format_set | ( | const char * | fmt | ) |

Set the format string of the displayed label.

If `NULL`, this sets the format to "%.0f". If not it sets the format string for the label text. The label text is provided a floating point value, so the label text can display up to 1 floating point value. Note that this is optional.

Use a format string such as "%1.2f meters" for example, and it will display values like: "3.14 meters" for a value equal to 3.14159.

Default is "%0.f".

EOAPI void elm_obj_spinner_wrap_set | ( | Eina_Bool | wrap | ) |

Set whether the spinner should wrap when it reaches its minimum or maximum value.

Disabled by default. If disabled, when the user tries to increment the value, but displayed value plus step value is bigger than maximum value, the new value will be the maximum value. The same happens when the user tries to decrement it, but the value less step is less than minimum value. In this case, the new displayed value will be the minimum value.

When wrap is enabled, when the user tries to increment the value, but displayed value plus step value is bigger than maximum value, the new value will be the minimum value. When the the user tries to decrement it, but the value less step is less than minimum value, the new displayed value will be the maximum value.

E.g.:

- min value = 10
- max value = 50
- step value = 20
- displayed value = 20

When the user decrement value (using left or bottom arrow), it will displays `50`.

Set whether the spinner should wrap when it reaches its minimum or maximum value.

Disabled by default. If disabled, when the user tries to increment the value, but displayed value plus step value is bigger than maximum value, the new value will be the maximum value. The same happens when the user tries to decrement it, but the value less step is less than minimum value. In this case, the new displayed value will be the minimum value.

When wrap is enabled, when the user tries to increment the value, but displayed value plus step value is bigger than maximum value, the new value will be the minimum value. When the the user tries to decrement it, but the value less step is less than minimum value, the new displayed value will be the maximum value.

E.g.:

- min value = 10
- max value = 50
- step value = 20
- displayed value = 20

When the user decrement value (using left or bottom arrow), it will displays `50`.

void elm_spinner::special_value_add | ( | double | value_,
|  | std::string | label_
| ) |  | const
| inline

Set a special string to display in the place of the numerical value.

It's useful for cases when a user should select an item that is better indicated by a label than a value. For example, weekdays or months.

E.g.:

sp = elm_spinner_add(win);
elm_spinner_min_max_set(sp, 1, 3);
elm_spinner_special_value_add(sp, 1, "January");
elm_spinner_special_value_add(sp, 2, "February");
elm_spinner_special_value_add(sp, 3, "March");
evas_object_show(sp);

Note
  If another label was previously set to `value`, it will be replaced by the new label.

  label | The label to be used.
