java - 如何禁用 JavaFX 中的最大化选项？

Question

我正在创建一个 JavaFX 程序。我已经使用 .fxml 代码来设计页面，但有一个问题，每当我运行程序时，它都可以在默认高度和宽度下正常工作，但是当我最大化该结果时，按钮和其他内容仍保持在默认高度的原始位置和宽度。他们没有调整高度和宽度。因为它是一个mp3播放器并且可以执行一些其他小功能，所以我希望它的大小不应该是可扩展的(它不能最大化)。这也能解决我的问题。

.fxml代码

如何禁用 JavaFX 中的最大化选项？

如何通过尺寸扩展改变内容位置？

Answer 1

如果您设置resizable property将 Stage 设置为 false 它会禁用最大化按钮，同时保留最小化按钮。

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        // Create Scene and add it to primaryStage
        primaryStage.setResizable(false);
        primaryStage.show();
    }
}

这只会阻止用户调整 Stage 的大小，但不会阻止您(开发人员)以编程方式调整 Stage 的大小。

Defines whether the Stage is resizable or not by the user. Programatically you may still change the size of the Stage. This is a hint which allows the implementation to optionally make the Stage resizable by the user.

Javadoc 表明这只是实现的提示。不过，我只能在 Windows 10 计算机上对此进行测试，但您在问题评论中提到它可以在 Linux 计算机上运行。
