CrVectorCrVector — A simple two point line vector where the end point can be optionally drawn to device coordinates. |

"end-scaleable" gboolean : Read / Write "x2" gdouble : Read / Write "y2" gdouble : Read / Write
The is a simple way to create a two point line vector. The only difference between this object and CrLine is that the "x2" and "y2" properties can be optionally referenced to device space.
CrItem* cr_vector_new (CrItem *parent, double x, double y, double x2, double y2, const gchar *first_arg_name, ...);
A convenience function to create a simple line vector and add it to a canvas item parent group in one step.
|
The parent item. |
|
The starting point of the vector. |
|
The starting point of the vector. |
|
The relative ending point of the vector along the x-axis. |
|
The relative ending point of the vector along the y-axis. |

Returns : |
A reference to a new CrItem. You must call g_object_ref if you intend to use this reference outside the local scope. |
"end-scaleable" property"end-scaleable" gboolean : Read / Write
True if the end of the vector is tied to item coordinate space. FALSE if the end of the vector is tied to device coordinate space.
Default value: TRUE
"x2" property"x2" gdouble : Read / Write
The length of the vector in the positive x-axis direction.
Default value: 0
"y2" property"y2" gdouble : Read / Write
The length of the vector in the positive y-axis direction.
Default value: 0
