JavaFx旋转文本

Question

嗨我想要旋转文字（-40）/我有问题，当文字很短这个开始不同的时候我希望那个文字开始时我标记。这个朋友我喜欢这个

for(int i =0 ;i<Config.busSizeInView;i++){
            nameBusStop.add(new Text("Konstytucji 3 Maja - Dworzec PKS 02"));
        }
for(int i=0 ; i<nameBusStop.size(); i++){
        nameBusStop.get(i).setRotate(-40);
        nameBusStop.get(i).setText(Main3.listBusStops.get(i).getName());
        }
for(int i =0 ; i<nameBusStop.size(); i++){
            nameBusStop.get(i).relocate(i*Config.xSize/Config.busSizeInView-Config.padding-10, Config.ySize - Config.ySize/6  - Config.padding*3);
        }   





line.getChildren().addAll(canvas,txtPane);
Pane txtPane = new Pane();
        for(Text text : nameBusStop){
            text.setFont(Font.font ("Verdana", 20));
            txtPane.getChildren().add(text);
        }
  line.getChildren().addAll(canvas,txtPane);

我这样做

- (void) viewWillAppear:(BOOL)animated
{
  self.navigationController.navigationBar.tintColor = [UIColor redColor]  
}

文字较长时 {{3}}

您也可以使用Canvas绘制字符串：

public static void drawStop(double x, double y, String text, GraphicsContext gc) {
    gc.save();

    gc.translate(x, y);
    gc.fillRect(-5, 0, 10, 10);
    gc.rotate(-40);
    gc.fillText(text, 5, 0);

    gc.restore();
}

@Override
public void start(Stage primaryStage) {
    Canvas canvas = new Canvas(900, 400);
    GraphicsContext gc = canvas.getGraphicsContext2D();

    gc.setFont(Font.font ("Verdana", 20));

    drawStop(100, 380, "Stop 1", gc);
    drawStop(200, 380, "Stop 2", gc);
    drawStop(500, 380, "Stop 3 Stop 3 Stop 3 Stop 3 Stop 3 Stop 3", gc);

    Scene scene = new Scene(new Group(canvas));

    primaryStage.setScene(scene);
    primaryStage.show();
}

或者，不要使用以儿童为中心的StackPane。也不要使用rotate属性，因为它围绕Node的中心旋转。请使用Rotate转换来围绕(0, 0)旋转：

public static void drawStop(double x, double y, String text, GraphicsContext gc, Pane pane) {
    gc.fillRect(x-5, y, 10, 10);
    Text textNode = new Text(text);
    textNode.setFont(Font.font ("Verdana", 20));
    textNode.setBoundsType(TextBoundsType.VISUAL);
    textNode.relocate(x, y-15);
    textNode.getTransforms().add(new Rotate(-40));
    pane.getChildren().add(textNode);
}

@Override
public void start(Stage primaryStage) {
    Pane pane = new Pane();
    Canvas canvas = new Canvas(900, 400);
    pane.getChildren().add(canvas);

    GraphicsContext gc = canvas.getGraphicsContext2D();

    drawStop(100, 380, "Stop 1", gc, pane);
    drawStop(200, 380, "Stop 2", gc, pane);
    drawStop(500, 380, "Stop 3 Stop 3 Stop 3 Stop 3 Stop 3 Stop 3", gc, pane);

    Scene scene = new Scene(pane);

    primaryStage.setScene(scene);
    primaryStage.show();
}
