Scala的JavaFX2绑定：ScalaFX

ScalaFX是JavaFX 2.0的Scala绑定(UI DSL)，主要特性如下：
1）对程序员友好的层次结构式的对象创建语法。
stage = new Stage { title.value = "Hello Stage" width = 600 height = 450 scene = new Scene { fill = Color.LIGHTGREEN content = new Rectangle { x = 25 y = 40 width = 100 height = 100 fill <== when (hover) then Color.GREEN otherwise Color.RED } } } 2）易于理解的属性绑定(Binding)语法。
height <== rect1.height + rect2.height
width <== max(rect1.width, rect2.width, rect3.width)
color <== when (hover) then Color.GREEN otherwise Color.RED
text <== when (rect.hover || circle.hover && !disabled) then textField.text + " is enabled" otherwise "disabled"
rect.hover onInvalidate { needsRepaint = true }3）精心设计的动画语法。Seq( at(0 s) {circle.centerX -> random * 800}, at(0 s) {circle.centerY -> random * 600}, at(40 s) {circle.centerX -> random * 800}, at(40 s) {circle.centerY -> random * 600} )4）类型安全的API。5）无缝的JavaFX/ScalaFX互操作。
