AdgArrow

typedef struct _AdgArrow AdgArrow;

All fields are private and should not be used directly. Use its public methods instead.

adg_arrow_set_angle ()

void                adg_arrow_set_angle                 (AdgArrow *arrow,
                                                         gdouble angle);

Sets a new angle: angle will be the new opening angle of arrow. Changing the arrow angle will invalidate arrow.

arrow :

an AdgArrow

angle :

the new angle

adg_arrow_get_angle ()

gdouble             adg_arrow_get_angle                 (AdgArrow *arrow);

Gets the current angle of arrow.

arrow :

an AdgArrow

Returns :

the arrow angle, in radians

Property Details

The "angle" property

  "angle"                    gdouble               : Read / Write

The opening angle of the arrow.

Allowed values: [0,6.28319]

Default value: 0.523599
