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 widgets 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 three 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 * Default contents parts of the button widget that you can use for are:
32 * @li "icon" - An icon of the button
34 * Default text parts of the button widget that you can use for are:
35 * @li "default" - Label of the button
37 * Follow through a complete example @ref button_example_01 "here".
42 * Add a new button to the parent's canvas
44 * @param parent The parent object
45 * @return The new object or NULL if it cannot be created
47 EAPI Evas_Object *elm_button_add(Evas_Object *parent);
50 * Turn on/off the autorepeat event generated when the button is kept pressed
52 * When off, no autorepeat is performed and buttons emit a normal @c clicked
53 * signal when they are clicked.
55 * When on, keeping a button pressed will continuously emit a @c repeated
56 * signal until the button is released. The time it takes until it starts
57 * emitting the signal is given by
58 * elm_button_autorepeat_initial_timeout_set(), and the time between each
59 * new emission by elm_button_autorepeat_gap_timeout_set().

62 * @param on A bool to turn on/off the event

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