| parent | the Group to which the new Leaf will be added. |
| x | the leaf origin horizontal position. |
| y | the leaf origin vertical position. |
| radius | the leaf radius. |
| client | the ItemClient for the new Leaf if any. |
Creates a new Leaf inside parent and sets client as its associated ItemClient. The origin is the angular point, and the radius the distance between the origin and the opposite point.
|
virtual |
The destructor.

Implementation of Item::Distance() for the Leaf class. Sets item to this.
Reimplemented from gccv::Item.

| void gccv::Leaf::SetWidthFactor | ( | double | factor | ) |
| factor | the new width factor. |
Sets the width of the leaf relative to its radius. Actually, the width is 0.8 * factor * radius.
|
protectedvirtual |
Evaluates the Leaf bounds.
