Class Line

javafx.scene.shape.Line

All Implemented Interfaces:: Styleable, EventTarget

public class Line extends Shape

This Line represents a line segment in (x,y) coordinate space. Example:

import javafx.scene.shape.*;

Line line = new Line();
line.setStartX(0.0f);
line.setStartY(0.0f);
line.setEndX(100.0f);
line.setEndY(100.0f);
}

Since:: JavaFX 2.0
