## Functions

### gtk_gesture_stylus_new ()

    GtkGesture *
    gtk_gesture_stylus_new (GtkWidget *widget);

Creates a new GtkGestureStylus.

#### Parameters

widget | a GtkWidget |

#### Returns

a newly created stylus gesture

### gtk_gesture_stylus_get_axis ()

    gboolean
    gtk_gesture_stylus_get_axis (GtkGestureStylus *gesture,
                                 GdkAxisUse axis,
                                 gdouble *value);

Returns the current value for the requested `axis` . This function must be called from either the “down”, “motion”, “up” or “proximity” signals.

#### Parameters

gesture | a GtkGestureStylus |
axis | requested device axis |
value | return location for the axis value. | [out]

#### Returns

TRUE if there is a current value for the axis

Since: 3.24

### gtk_gesture_stylus_get_axes ()

    gboolean
    gtk_gesture_stylus_get_axes (GtkGestureStylus *gesture,
                                 GdkAxisUse axes[],
                                 gdouble **values);
