JavaFX HBox

HBox布局窗格将节点排列在一行中。它由javafx.scene.layout.HBox类表示。我们只需要实例化HBox类即可创建HBox布局。

物产

下表提供了类的属性及其设置方法。

Property Description Setter Methods
alignment This represents the alignment of the nodes. setAlignment(Double)
fillHeight This is a boolean property. If you set this property to true the height of the nodes will become equal to the height of the HBox. setFillHeight(Double)
spacing This represents the space between the nodes in the HBox. It is of double type. setSpacing(Double)

建设者

HBox类包含以下两个构造函数。

  • new HBox() ：创建间距为0的HBox布局
  • 新的Hbox(双倍间距) ：使用间距值创建HBox布局

例

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Label_Test extends Application {

@Override
public void start(Stage primaryStage) throws Exception {
Button btn1 = new Button("Button 1");
Button btn2 = new Button("Button 2");
HBox root = new HBox();
Scene scene = new Scene(root,200,200);
root.getChildren().addAll(btn1,btn2);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}

}

示例：在节点之间设置空间。

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Label_Test extends Application {

@Override
public void start(Stage primaryStage) throws Exception {
Button btn1 = new Button("Button 1");
Button btn2 = new Button("Button 2");
HBox root = new HBox();
Scene scene = new Scene(root,200,200);
root.getChildren().addAll(btn1,btn2);
root.setSpacing(40);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}

}
