## Description

GtkGestureMultiPress is a GtkGesture implementation able to recognize multiple clicks on a nearby zone, which can be listened for through the “pressed” signal. Whenever time or distance between clicks exceed the GTK+ defaults, “stopped” is emitted, and the click counter is reset.

Callers may also restrict the area that is considered valid for a >1 touch/button press through `gtk_gesture_multi_press_set_area()`, so any click happening outside that area is considered to be a first click of its own.

## Functions

### gtk_gesture_multi_press_new ()

    GtkGesture *
    gtk_gesture_multi_press_new (GtkWidget *widget);

Returns a newly created GtkGesture that recognizes single and multiple presses.

#### Parameters

widget | a GtkWidget |

#### Returns

a newly created GtkGestureMultiPress

Since: 3.14

### gtk_gesture_multi_press_set_area ()

    void
    gtk_gesture_multi_press_set_area (GtkGestureMultiPress *gesture,
                                      const GdkRectangle *rect);

If `rect` is non-`NULL`, the press area will be checked to be confined within the rectangle, otherwise the button count will be reset so the press is seen as being the first one. If `rect` is `NULL`, the area will be reset to an unrestricted state.

Note: The rectangle is only used to determine whether any non-first click falls within the expected area. This is not akin to an input shape.

#### Parameters

gesture | a GtkGestureMultiPress |
rect | rectangle to receive coordinates on. | [allow-none]

Since: 3.14

### gtk_gesture_multi_press_get_area ()

    gboolean
    gtk_gesture_multi_press_get_area (GtkGestureMultiPress *gesture,
                                      GdkRectangle *rect);

If an area was set through `gtk_gesture_multi_press_set_area()`, this function will return `TRUE` and fill in `rect` with the press area. See `gtk_gesture_multi_press_set_area()` for more details on what the press area represents.

#### Parameters

gesture | a GtkGestureMultiPress |
rect | return location for the press area. | [out]

#### Returns

`TRUE` if `rect` was filled with the press area

Since: 3.14

## Types and Values

### GtkGestureMultiPress

    typedef struct _GtkGestureMultiPress GtkGestureMultiPress;

## Signal Details

### The `“pressed”` signal

    void
    user_function (GtkGestureMultiPress *gesture,
                   int                   n_press,
                   double                x,
                   double                y,
                   gpointer              user_data)

This signal is emitted whenever a button or touch press happens.

#### Parameters

gesture | the object which received the signal |
n_press | how many touch/button presses happened with this one |
x | The X coordinate, in widget allocation coordinates |
y | The Y coordinate, in widget allocation coordinates |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since: 3.14

### The `“released”` signal

    void
    user_function (GtkGestureMultiPress *gesture,
                   int                   n_press,
                   double                x,
                   double                y,
                   gpointer              user_data)

This signal is emitted when a button or touch is released. `n_press` will report the number of press that is paired to this event, note that “stopped” may have been emitted between the press and its release, `n_press` will only start over at the next press.

#### Parameters

gesture | the object which received the signal |
n_press | number of press that is paired with this release |
x | The X coordinate, in widget allocation coordinates |
y | The Y coordinate, in widget allocation coordinates |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since: 3.14

### The `“stopped”` signal

    void
    user_function (GtkGestureMultiPress *gesture,
                   gpointer              user_data)

This signal is emitted whenever any time/distance threshold has been exceeded.

#### Parameters

gesture | the object which received the signal |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since: 3.14
