如何在 JavaFX 中创建 SplitPane?
SplitPane 是一个 UI 组件,包含两个或多个面,中间有一个分隔符。此分隔符可移动;你可以使用它来减少/增加一面的区域。你可以通过实例化 javafx.scene.control.SplitPane 类来创建分割窗格。
SplitPane 的边可以水平或垂直排列。默认情况下,创建的 SplitPane 是水平的,你可以使用 setOrientation() 方法来更改其方向。
示例
以下示例演示了如何创建 SplitPane。
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.SplitPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class SplitPaneExample extends Application {
public void start(Stage stage) throws FileNotFoundException {
//Creating ImageView object1
Image img1 = new Image(new FileInputStream("D:\images\elephant.jpg"));
ImageView view1 = new ImageView(img1);
view1.setFitWidth(250);
view1.setFitHeight(150);
//Creating ImageView object2
Image img2 = new Image(new FileInputStream("D:\images\boy.jpg"));
ImageView view2 = new ImageView(img2);
view2.setFitWidth(250);
view2.setFitHeight(150);
//Creating a SplitPane
SplitPane splitPane = new SplitPane();
//Creating stack panes holding the ImageView objects
StackPane stackPane1 = new StackPane(view1);
StackPane stackPane2 = new StackPane(view2);
//Adding the stackpanes to the splitpane
splitPane.getItems().addAll(stackPane1, stackPane2);
//Setting anchor pane as the layout
AnchorPane pane = new AnchorPane();
AnchorPane.setTopAnchor(splitPane, 15.0);
AnchorPane.setRightAnchor(splitPane, 15.0);
AnchorPane.setBottomAnchor(splitPane, 15.0);
AnchorPane.setLeftAnchor(splitPane, 15.0);
pane.getChildren().addAll(splitPane);
pane.setStyle("-fx-background-color: BEIGE");
//Setting the stage
Scene scene = new Scene(pane, 595, 300);
stage.setTitle("Split Pane");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}输出
