javafx之CSS初探
javaFX 可以通过css来设计界面。javafx中的css只是w3c css2.1规范的一个扩展和子集,并不完全支持所有的css特性。
javafx中的css元素必须有-fx-前缀。
一、介绍
选择器分类:
Type选择器:通过Node的getTypeSelector可以获取
id选择器:通过设定id=属性(注意这里的id不是fx:id)
styleClass属性: styleClass可以使用class选择器
选择器命名规范:如ToggleButton需要写成:toggle-button
与w3c css语法的一些区别:
1.不支持@font?face, @-keyword 等
2.不支持层次伪类选择器
3.伪类:active,:focus等,在Nodes中变为:pressed, :focused
4.超链接伪类:link,:visited变为:visited
5.javafx中不支持逗号序列的值,如不能再-fx-font-family以逗号分隔同时指导fontsize等
6.javafx css使用HSB颜色模型代替HSL
7、javafx css不会对uri进行编码
关于Inheritance继承
举例:
Scene scene = new Scene(new Group()); scene.getStylesheets().add(“test.css”); Rectangle rect = new Rectangle(100,100); rect.setLayoutX(50); rect.setLayoutY(50); rect.getStyleClass().add("my-rect"); ((Group)scene.getRoot()).getChildren().add(rect);
.my-rect { -fx-fill: red; }
.my-rect { -fx-fill: yellow; -fx-stroke: green; -fx-stroke-width: 5; -fx-stroke-dash-array: 12 2 4 2; -fx-stroke-dash-offset: 6; -fx-stroke-line-cap: butt; }

image-pattern("images/Duke.png", 20%, 20%, 80%, 80%, true)
image-pattern("images/Duke.png", 20, 20, 80, 80, false)

}
.button { -fx-background-color: abc }
- .label { -fx-text-fill: #ff0000 } /* #rrggbb */
- .label { -fx-text-fill: rgb(255,0,0) }
- .label { -fx-text-fill: rgb(100%, 0%, 0%) }
- .label { -fx-text-fill: rgba(255,0,0,1) }
