|
* line->setTailDecoratorStyle(JKQTPCircleDecorator);
|
|

* This results in arrows drawn at the start (aka x1/y1, =tail) and end (aka x2/y2, =head) of the line.
|

*
|
|

|
|
* \note The convenience class JKQTPGeoArrow activates line-end decorations (aka arows) by default and allows to select them in the constructor.
