问题描述

如何创建一个窗格并让一个孩子节点放在中心?

How do I create a Pane and have a child Node put at the center?

让我们说 Pane 500 500 节点 ImageView 200 200 图像

Lets say the Pane is 500 by 500 and the Node is an ImageView with a 200 by 200 Image

ImageView view = new ImageView();

Image img = new Image("test.png");
view.setImage(img);
Pane pane = new Pane();
pane.setMinWidth(500);
pane.setMinHeight(500);
pane.getChildren().add(view);


推荐答案

您有2个选择:


  1. 例如使用 StackPane 代替 Pane (因为你可以使用)

  1. For example using StackPane instead of Pane (because you can use Pos)

StackPane p = new StackPane();
p.setPrefSize(700,700); //set a default size for your stackpane
Image img = new Image("test.png"); //create an image
ImageView v = new ImageView(img); //create an imageView and pass the image

p.getChildren().add(v); //add imageView to stackPane
StackPane.setAlignment(v,Pos.CENTER_LEFT); //set it to the Center Left(by default it's on the center)
stage.setScene(new Scene(p));
stage.show();


  • 您可以使用 JavaFx Scene Builder ,它是一个可视化的布局JavaFx的工具。
    例如,如果我想创建一个 Hbox 布局:

  • You can use JavaFx Scene Builder, it's a visual layout tool for JavaFx.For example if I want to create a Hbox layout:

    <?xml version="1.0" encoding="UTF-8"?>
    
        <?import java.lang.*?>
        <?import java.net.*?>
        <?import java.util.*?>
        <?import javafx.geometry.*?>
        <?import javafx.scene.*?>
        <?import javafx.scene.control.*?>
        <?import javafx.scene.effect.*?>
        <?import javafx.scene.image.*?>
        <?import javafx.scene.layout.*?>
        <?import javafx.scene.shape.*?>
        <?import javafx.scene.text.*?>
    
        <HBox alignment="CENTER" prefHeight="369.0" prefWidth="425.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" >
            <children>
                <ImageView fitHeight="150.0" fitWidth="200.0" pickOnBounds="true" preserveRatio="true" x="0.0" HBox.hgrow="NEVER">
                    <image>
                        <Image url="@../yourImg.png" />
                    </image>
                </ImageView>
            </children>
        </HBox>
    

    将其保存为 myLayout.fxml 里面您的主类并在代码中添加以下内容:

    save-it as myLayout.fxml inside your main class and add following to your code:

    Hbox root = FXMLLoader.load(getClass().getResource("myLayout.fxml"));
    Scene scene = new Scene(root);
    stage.setScene(scene);
    stage.show();
