| parent | the Group to which the new Arrow will be added. |
| xstart | the horizontal start position. |
| ystart | the vertical start position. |
| xend | the horizontal end position. |
| yend | the vertical end position. |
| client | the ItemClient for the new Arrow if any. |
Creates a new Arrow with a full head at end and no head at start inside parent and sets client as its associated ItemClient.

| x | horizontal position |
| y | vertical position |
| item | where to store the Item. |
Implementation of Item::Distance() for the Arrow class. Sets item to this.
Reimplemented from gccv::Item.

virtual |
| cr | a cairo_t. |
| is_vector | whether the cairo_t is a vectorial context. |
Draws the Arrow to cr.
