在JavaFX中,fx:id和id:有什么区别? [英] What's the difference between fx:id and id: in JavaFX?
问题描述
也许是一个非常新手的问题....
我正在使用Scene Builder开始在FMXL应用程序中学习JavaFX,阅读本教程:
http ://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm
所以,一旦我应用了一些更改,这2个ID的问题出现了...我可能已经错过或混淆了一些关于他们的事情......
任何人都可以告诉我他们在哪些情况下使用过它们或者另一个?
id
您用来设置 CSS ID 到你的组件,例如< Text id =welcome-text... />
并在你的样式表中你有类似<$ c $的东西c>#welcome-text {font-size:16pt; } 所以这将应用于你的文本
。
fx:id
如果你想在Controller类中使用你的组件,你可以使用它们,你可以用 @FXML Text myWelcomeText
注释它们。 / p>
Maybe a really newbie's question....
I'm starting learning JavaFX in a FMXL Application using the Scene Builder, by reading this tutorials:
http://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm
So once i applied some changes, an issue with this 2 IDs came up... I might have missed or confused something about them...
Can anyone tell me in which cases they are used one or another?
id
you use to set a CSS ID to your Component, for example <Text id="welcome-text" .../>
and in your stylesheet you have something like #welcome-text { font-size: 16pt; }
so this will be applied to your Text
.
fx:id
you use if you want to work with your Components in your Controller class, where you annotate them with @FXML Text myWelcomeText
.
