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

java8中新增了javafx.css开放了css相关api。

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;
}

语法排错:

WARNING: com.sun.javafx.css.parser.CSSParser declaration Expected ‘‘ while parsing ‘-fx-background-color‘ at ?[1,49]

[line, position]



Types

inherit
boolean
string
number
integer
size
angle
point {x,y}
percentage %
uri url(http://example.com)

effect:
 javafx css支持DropShadow与InnerShadow
dropshadow( , , , , , )
innershadow(  ,  ,  ,  ,  )

= [ gaussian | one-pass-box | three-pass-box | two-pass-box ]


font
-fx-font-family: [serif/sans-serif/cursive/fantasy/monospace]
-fx-font-size
-fx-font-style: [normal| italic | oblique]
-fx-font-weight: [normal| bold| bolder| lighter| 100| ...|900]
-fx-font: [[ || ]? ]

paint

Linear Gradients
linear-gradient( [ [from  to ] | [ to ], ]? [ [ repeat | reflect ], ]? [, ]+) 

t from top left to bottom right of the filled area with red at the top left corner and black at the bottom right.
linear-gradient(to bottom right, red, black)
  linear-gradient(from 0% 0% to 100% 100%, red 0%, black 100%)
create a 50px high bar at the top with a 3 color gradient with white underneath for the rest of the filled area.
linear-gradient(from 0px 0px to 0px 50px, gray, darkgray 50%, dimgray 99%, white)

Radial Gradient
radial-gradient([ focus-angle , ]? [ focus-distance , ]? [ center , ]? radius [ | ] [ [ repeat | reflect ], ]?[, ]+)

radial-gradient(radius 100%, red, darkgray, black)

radial-gradient(focus-angle 45deg, focus-distance 20%, center 25% 25%, radius 50%, reflect, gray, darkgray 75%, dimgray)


Image Paint
image-pattern(, [[, ]?]?)
 The URL of the image.
 The x origin of the anchor rectangle.
 The y origin of the anchor rectangle.
 The width of the anchor rectangle.
 The height of the anchor rectangle.
 The proportional flag which indicates whether start and end locations are proportional or absolute

image-pattern("images/Duke.png")

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

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

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

image-pattern("images/Duke.png", 0, 0, imageWidth, imageHeight, false)
repeating-image-pattern("com/mycompany/myapp/images/Duke.png")

color
.button {
    -fx-background-color: red;
}

looked-up Colors:很有用的一个特性可以引用颜色值,举例秒懂
.root { abc: #f00 }
.button { -fx-background-color: abc }

rgb colors:

.label { -fx-text-fill: #f00 } /* #rgb */
  • .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) }

javafx一些类中的css属性:

root.popup来进行styled
