问题描述
我对JavaFX完全陌生，老实说，我对Java中的任何UI开发都非常了解.我正在使用fxml定义屏幕布局.
I am completely new to JavaFX, well any UI development in Java if I am honest. I am using fxml to define my screen layout.
我想要一个使用选项卡的应用程序，并且第一个选项卡的内部布局与IssueTracker示例应用程序非常相似.我已经创建了下面的fxml文件，看起来差不多，但是，当我调整应用程序的大小时，选项卡及其内容不会随屏幕调整大小.
I want an application that uses tabs, witht he first tab having an internal layout rather similar to the IssueTracker sample application. I have created the below fxml file which looks about right, however when I resize the application the tabs and their contents do not resize with the screen.
如何调整大小?我需要在代码中执行还是可以在fxml中执行?
How do I make this resize? Do I need to do it within code or can I do it within the fxml?
谢谢

推荐答案
Javafx组件会根据可用大小自动调整自身.尝试删除prefHeight和prefWidth，因为它会强制组件使用特定尺寸.
Javafx components automatically adjust themselves according to the size available to them. Try removing the prefHeight and prefWidth, as it forces the components to use a particular dimension.
