In JavaFX styling is done by using CSS.
在 JavaFX 中，样式是通过使用 CSS 完成的。
.button{
-fx-border-color: transparent;
-fx-border-width: 0;
-fx-background-radius: 0;
-fx-background-color: transparent;
-fx-font-family:"Segoe UI", Helvetica, Arial, sans-serif;
-fx-font-size: 1em; /* 12 */
-fx-text-fill: #828282;
}
.button:focused {
-fx-border-color: transparent, black;
-fx-border-width: 1, 1;
-fx-border-style: solid, segments(1, 2);
-fx-border-radius: 0, 0;
-fx-border-insets: 1 1 1 1, 0;
}
.button:pressed {
-fx-background-color: black;
-fx-text-fill: white;
}
Add this code to a CSS file, save it to the directory where the source file of the control exists which contains you buttons. Then in this class:
将此代码添加到 CSS 文件中，并将其保存到包含按钮的控件源文件所在的目录中。然后在这个类中：
getStylesheets().add(getClass().getResource("nameofyourcssfile.css").toExternalForm());
Then all of the buttons that that object contain will use this style-classes.
然后该对象包含的所有按钮都将使用此样式类。
Modification on your need is straightforward.
根据您的需要进行修改很简单。

JavaFX has a Hyperlinkcontrolwhich basically has all the functionality you are looking for. It fires ActionEvents in the same way as a button:
JavaFX 有一个Hyperlink控件，它基本上具有您正在寻找的所有功能。它ActionEvent以与按钮相同的方式触发s：
Hyperlink button = new Hyperlink("Some text");
button.setOnAction(e -> System.out.println("Hyperlink clicked"));
Like a link in a web page, it will appear in a different color if it has been "visited", i.e. if an action has been fired on it.
就像网页中的链接一样，如果它被“访问”，即如果一个动作被触发，它将以不同的颜色显示。
