FlowPane将node从左到右水平或从上到下垂直放置在pane中，分别用到Orientation.HORIZONTAL和Orientation.VERTICAL方法。
我们也可以设置node之间的距离，下面的例子演示FlowPane的用法：
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;
public class ShowFlowPane extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
// Create a pane and set its properties
FlowPane pane = new FlowPane();
pane.setPadding(new Insets(11,12,13,14));
pane.setHgap(5);
pane.setVgap(5);
// Place nodes in the pane
pane.getChildren().addAll(new Label("First Name:"),
new TextField(), new Label("MI:"));
TextField tfMi = new TextField();
tfMi.setPrefColumnCount(1);
pane.getChildren().addAll(tfMi, new Label("Last Name:"),new TextField());
// Create a scene and place it in the stage
Scene scene = new Scene(pane, 200,250);
primaryStage.setTitle("ShowFlowPane");// Set the stage title
primaryStage.setScene(scene);// Place the scene in the stage
primaryStage.show();// Display the stage
}
}
说明：
1、本代码运行的结果如下：
2、Insets对象确定pane边界的距离，如下图所示：
3、tfMi.setPrefColumnCount(1)将MI text field优选的列数设为1。
