JavaFX 中 2D 形状的 Stroke Width 属性说明
Stroke Width 属性指定了形状边界线的宽度。可以使用 javafx.scene.shape.Shape 类的 setWidth() 方法设置宽度。此方法接受 double 值作为参数,并绘制指定宽度的边界。
如果没有将任何值作为参数传递给此方法,则默认情况下它会将宽度视为 1.0。
示例
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Polygon; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.scene.text.Text; import javafx.stage.Stage; public class StrokeWidthExample extends Application { public void start(Stage stage) { Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12); Text label1 = new Text("Original Image"); label1.setFont(font); label1.setX(250.0); label1.setY(125.0); Polygon rhombus1 = new Polygon(300.0, 0.0, 250.0, 50.0, 300.0, 100.0, 350.0, 50.0); Text label2 = new Text("Stroke Width: none"); label2.setFont(font); label2.setX(25.0); label2.setY(275.0); Polygon rhombus2 = new Polygon(100.0, 150.0, 50.0, 200.0, 100.0, 250.0, 150.0, 200.0); rhombus2.setStroke(Color.BLUE); Text label3 = new Text("Stroke Width: 3"); label3.setFont(font); label3.setX(250.0); label3.setY(275.0); Polygon rhombus3 = new Polygon(300.0, 150.0, 250.0, 200.0, 300.0, 250.0, 350.0, 200.0); rhombus3.setStroke(Color.BLUE); rhombus3.setStrokeWidth(3.0); Text label4 = new Text("Stroke Width: 10"); label4.setFont(font); label4.setX(430.0); label4.setY(275.0); Polygon rhombus4 = new Polygon(490.0, 150.0, 440, 200.0, 490.0, 250.0, 540.0, 200.0); rhombus4.setStroke(Color.BLUE); rhombus4.setStrokeWidth(10.0); //Creating a Group object Group root = new Group(label1, label2, label3, label4, rhombus1, rhombus2, rhombus3, rhombus4); //Creating a scene object Scene scene = new Scene(root, 595, 310); //Setting title to the Stage stage.setTitle("Stroke Width"); //Adding scene to the stage stage.setScene(scene); //Displaying the contents of the stage stage.show(); } public static void main(String args[]){ launch(args); } }
