JavaFX FlowPane

FlowPane布局窗格将流中的节点组织起来，并包裹在流窗格的边界处。水平流窗格将节点排成一排，并根据流窗格的宽度对其进行包装。垂直流窗格将节点排列成一列，并根据流窗格的高度将它们包裹起来。 FlowPane布局由javafx.scene.layout.FlowPane类表示。我们只需要实例化此类即可创建流窗格布局。

属性

下表中描述了该类的各种属性。

Property Description Setter Methods
alignment The overall alignment of the flowpane’s content. setAlignment(Pos value)
columnHalignment The horizontal alignment of nodes within the columns. setColumnHalignment(HPos Value)
hgap Horizontal gap between the columns. setHgap(Double value)
orientation Orientation of the flowpane setOrientation(Orientation value)
prefWrapLength The preferred height or width where content should wrap in the horizontal or vertical flowpane. setPrefWrapLength(double value)
rowValignment The vertical alignment of the nodes within the rows. setRowValignment(VPos value)
vgap The vertical gap among the rows setVgap(Double value)

建设者

该类中有以下8个构造函数。

  • FlowPane()
  • FlowPane(双Hgap，双Vgap)
  • FlowPane(Double Hgap，Double Vgap，Node？子级)
  • FlowPane(节点…孩子)
  • FlowPane(方向方向)
  • FlowPane(方向，双Hgap，双Vgap)
  • FlowPane(方向，双Hgap，双Vgap，Node？子级)
  • FlowPane(方向方向，节点…子级)

例

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;

public class FlowPaneTest extends Application {

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("FlowPane Example");
        FlowPane root = new FlowPane();
        root.setVgap(6);
        root.setHgap(5);
        root.setPrefWrapLength(250);
        root.getChildren().add(new Button("Start"));
        root.getChildren().add(new Button("Stop"));
        root.getChildren().add(new Button("Reset"));
        Scene scene = new Scene(root,300,200);
 
        primaryStage.setScene(scene);
        primaryStage.show();
    }
 
    public static void main(String[] args) {
        launch(args);
    }
}
