Detailed Description




This is a push-button. Press it and run some function. It can contain a simple label and icon object and it also has an autorepeat feature.
This widget inherits from the Layout one, so that all the functions acting on it also work for button objects.
This widget emits the following signals, besides the ones sent from Layout:
- "clicked": the user clicked the button (press/release).
- "repeated": the user pressed the button without releasing it.
- "pressed": button was pressed.
- "unpressed": button was released after being pressed. In all cases, the
event
parameter of the callback will beNULL
.
Also, defined in the default theme, the button has the following styles available:
- default: a normal button.
- anchor: Like default, but the button fades away when the mouse is not over it, leaving only the text or icon.
- hoversel_vertical: Internally used by Hoversel to give a continuous look across its options.
- hoversel_vertical_entry: Another internal for Hoversel.
- naviframe: Internally used by Naviframe for its back button.
- colorselector: Internally used by Colorselector for its left and right buttons.
Default content parts of the button widget that you can use for are:
- "icon" - An icon of the button
Default text parts of the button widget that you can use for are:
- "default" - Label of the button

Function Documentation
Evas_Object* elm_button_add | ( | Evas_Object * | parent | ) |
Add a new button to the parent's canvas.
- Parameters:
-
parent The parent object
- Returns:
- The new object or NULL if it cannot be created
Referenced by elm_fileselector_buttons_ok_cancel_set(), and elm_quicklaunch_seed().
double elm_button_autorepeat_gap_timeout_get | ( | const Evas_Object * | obj | ) |
Get the interval between each generated autorepeat event.
- Parameters:
-
obj The button object
- Returns:
- Interval in seconds
void elm_button_autorepeat_gap_timeout_set | ( | Evas_Object * | obj, |
double | t | ||
) |
Set the interval between each generated autorepeat event.
After the first repeated
event is fired, all subsequent ones will follow after a delay of t
seconds for each.
- Parameters:
-
obj The button object t Interval in seconds
Eina_Bool elm_button_autorepeat_get | ( | const Evas_Object * | obj | ) |
Get whether the autorepeat feature is enabled.
- Parameters:
-
obj The button object
- Returns:
- EINA_TRUE if autorepeat is on, EINA_FALSE otherwise
- See also:
- elm_button_autorepeat_set()
double elm_button_autorepeat_initial_timeout_get | ( | const Evas_Object * | obj | ) |
Get the initial timeout before the autorepeat event is generated.
- Parameters:
-
obj The button object
- Returns:
- Timeout in seconds
void elm_button_autorepeat_initial_timeout_set | ( | Evas_Object * | obj, |
double | t | ||
) |
Set the initial timeout before the autorepeat event is generated.
Sets the timeout, in seconds, since the button is pressed until the first repeated
signal is emitted. If t
is 0.0 or less, there won't be any delay and the event will be fired the moment the button is pressed.
- Parameters:
-
obj The button object t Timeout in seconds
void elm_button_autorepeat_set | ( | Evas_Object * | obj, |
Eina_Bool | on | ||
) |
Turn on/off the autorepeat event generated when the button is kept pressed.
When off, no autorepeat is performed and buttons emit a normal clicked
signal when they are clicked.
When on, keeping a button pressed will continuously emit a repeated
signal until the button is released. The time it takes until it starts emitting the signal is given by elm_button_autorepeat_initial_timeout_set(), and the time between each new emission by elm_button_autorepeat_gap_timeout_set().
- Parameters:
-
obj The button object on A bool to turn on/off the event
