标签:javafx   css   

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 ‘<percent>‘ while parsing ‘-fx-background-color‘ at ?[1,49]

<url>[line, position]



Types

inherit
boolean
string
number
integer
size
angle
point {x,y}
percentage %

effect:
 javafx css支持DropShadow与InnerShadow
dropshadow( <blur-type> , <color> , <number> , <number> , <number> , <number> )
innershadow( <blur-type> , <color> , <number> , <number> , <number> , <number> )

<blur-type> = [ 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: [[ <font-style> || <font-weight> ]? <font-size> <font-family> ]

paint

Linear Gradients <linear-gradient>
linear-gradient( [ [from <point> to <point>] | [ to <side-or-corner>], ]? [ [ repeat | reflect ], ]? <color-stop>[, <color-stop>]+) 

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>
radial-gradient([ focus-angle <angle>, ]? [ focus-distance <percentage>, ]? [ center <point>, ]? radius [ <length> | <percentage> ] [ [ repeat | reflect ], ]?<color-stop>[, <color-stop>]+)

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>
image-pattern(<string>, [<size><size><size><size>[, <boolean>]?]?)
<string> The URL of the image.
<size> The x origin of the anchor rectangle.
<size> The y origin of the anchor rectangle.
<size> The width of the anchor rectangle.
<size> The height of the anchor rectangle.
<boolean> 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:

Stage

PopupWindow没有可以被css styled的properties,但是PopupWindow可以有自己的scene,可以通过scene的root节点
root.popup来进行styled
