An arrow consists of a tail and optionally an arrow head at the front.
Once an arrow object is created, the client code should provide configuration via the head() and tail() accessor methods. When all configuration is complete, the client code must invoke the generate() method to populate the entity set with the entities required for the arrow.

Creates an instance of TSLArrow.
After creation of the arrow, configure the head and tail as appropriate before finally calling generate().
|
static |
Creates an instance of TSLArrow, initialised with the points provided.
The returned arrow will have a closed (triangular) head at the front, and a tail following the coordinates defined by tailPoints, with a width of one pixel.
After creation of the arrow, configure the head and tail further as appropriate before finally calling generate().
| tailPoints | The set of points defining the arrow's tail. |
| armEnd | The endpoint of one arm of the arrow's head. |
| bool TSLArrow::generate | ( | ) |
Using the configuration set up in combination of the TSLArrow, TSLArrowHead and TSLArrowTail, the arrow geometry is created.
| TSLArrowHead * TSLArrow::head | ( | ) | const |
Gets or creates the TSLArrowHead. It creates a TSLArrowHead the first time it is called.
The application may modify the returned object but must not delete it. The TSLArrow object retains ownership of the head object.
| TSLArrowTail * TSLArrow::tail | ( | ) | const |
Gets the TSLArrowTail.
The application may modify the returned object but must not delete it. The TSLArrow object retains ownership of the tail object.
