11 * This is a push-button. Press it and run some function. It can contain
12 * a simple label and icon object and it also has an autorepeat feature.
14 * This widget emits the following signals:
15 * @li "clicked": the user clicked the button (press/release).
16 * @li "repeated": the user pressed the button without releasing it.
17 * @li "pressed": button was pressed.
18 * @li "unpressed": button was released after being pressed.
19 * In all cases, the @c event parameter of the callback will be
22 * Also, defined in the default theme, the button has the following styles
24 * @li default: a normal button.
25 * @li anchor: Like default, but the button fades away when the mouse is not
26 * over it, leaving only the text or icon.
27 * @li hoversel_vertical: Internally used by @ref Hoversel to give a
28 * continuous look across its options.
29 * @li hoversel_vertical_entry: Another internal for @ref Hoversel.
31 * XXX: add more styles in default theme.
33 * Default contents parts of the button widget that you can use for are:
34 * @li "icon" - An icon of the button
36 * Default text parts of the button widget that you can use for are:
37 * @li "default" - Label of the button

62 * Turn on/off the autorepeat event generated when the button is kept pressed
64 * When off, no autorepeat is performed and buttons emit a normal @c clicked
65 * signal when they are clicked.
67 * When on, keeping a button pressed will continuously emit a @c repeated
68 * signal until the button is released. The time it takes until it starts
69 * emitting the signal is given by
70 * elm_button_autorepeat_initial_timeout_set(), and the time between each
71 * new emission by elm_button_autorepeat_gap_timeout_set().
73 * @param obj The button object
74 * @param on A bool to turn on/off the event

89 * Set the initial timeout before the autorepeat event is generated
91 * Sets the timeout, in seconds, since the button is pressed until the
92 * first @c repeated signal is emitted. If @p t is 0.0 or less, there
93 * won't be any delay and the event will be fired the moment the button is

117 * After the first @c repeated event is fired, all subsequent ones will
118 * follow after a delay of @p t seconds for each.

121 * @param t Interval in seconds
