在javafx中保存最后一个窗口属性/内容

public class WindowProperties {
    private double x;
    private double y;
    private double width;
    private double height;
    private String content;

    // 省略构造函数和getter/setter方法
}

primaryStage.setOnCloseRequest(event -> {
    WindowProperties properties = new WindowProperties();
    properties.setX(primaryStage.getX());
    properties.setY(primaryStage.getY());
    properties.setWidth(primaryStage.getWidth());
    properties.setHeight(primaryStage.getHeight());
    properties.setContent(contentTextArea.getText());

    // 将WindowProperties对象保存到文件或数据库中
});

// 从文件或数据库中读取WindowProperties对象
WindowProperties properties = readWindowProperties();

if (properties != null) {
    primaryStage.setX(properties.getX());
    primaryStage.setY(properties.getY());
    primaryStage.setWidth(properties.getWidth());
    primaryStage.setHeight(properties.getHeight());
    contentTextArea.setText(properties.getContent());
}
