JavaFX Windows 设计在 Linux 上有所不同

Question

我在 Windows 上构建了以下 JavaFX 应用程序。 在 Linux 上，按钮大小和字体大小不匹配。 标签、文本字段和按钮描述不适合其尺寸。

如何设置程序的字体大小，使其看起来像在 windows 下？

手动更改字体大小和字体样式效果不佳，因为它不适合尺寸。或者我没有找到合适的组合。

提前致谢

使用 JDK 8 的 Windows 和 Linux。
- JavaFX 工具：Gluon 的 SceneBuilder

以下没有帮助：
Default font size of JavaFX under Linux is larger as on Windows
Modena – new theme for JavaFX 8

[编辑：我突然想到我在对主题有很多认识之前就想出了这个“解决方案”。下次我处理这个问题时，我将检查在 Windows 和 Mac/Linux 上显式地使主题相同（而不是允许它们各自的默认值）是否消除了这个问题。]

我很失望地发现著名的“一次编写——到处运行”程序有这个相当大的缺陷。我希望有一种更优雅的方式来处理它，或者我遗漏或误解的东西，但现在我正在为给定的操作系统指定大小。据我所知，只有两种操作系统的缩放大小需要适应：一方面是 Windows，另一方面是 Linux/Mac。

如果只有一两个尺寸需要调整，可以使用以下方法：

    String os = System.getProperty("os.name","generic").toLowerCase(Locale.US);
    if (os.indexOf("mac") > 0) {
        root.setStyle("-fx-font-size: 14pt");           
    }

在这种情况下，Windows 默认字体的大小为 10pt，而我的 Mac 用户想要更大的字体，而该程序并没有被广泛分发。一旦在场景图的基础上为组设置了样式（我通常将其命名为“根”），它将与整个图相关，除非被覆盖。

但对于更复杂的情况，我使用了类似以下静态类的东西。当我分发应用程序时，通常作为自包含程序（使用 JLINK），操作系统是已知的，可以在文件顶部设置。我还不如只发布整个班级。您可能会有不同的细节，或多或少需要调整的东西。

如果有更好的方法来处理这个问题，我会全力以赴。
