SESSION 11  Spark primitives

Label包含在spark.componets中

The classes in the spark.primitives package include BitmapImage, Ellipse, Graphic, Line, Path, Rect, RichEditableText, and RichText.

session11/src/Tester.mxml

  
    
    
    
     //M means "Move the pen", L means "Line from", and the rest are space-separated x and y values.这里没去理解
    
    
    
    
  

继承层次

The InteractiveObject class is an abstract base class for all the display object classes that the user can interact with using the keyboard and mouse.

Spark primitives are the building blocks on which Spark components are built.

Classes that can have a stroke extend StrokedElement ; classes that can have a fill extend FilledElement .

Classes that are interactive extend InteractiveObject .

SESSION 12  Simple Spark components

这里的组件基本上可以在FB中拖出来，了解怎么用即可

       //双向数据绑定
      
      
      
      
      
    
    
      
      
      
      
      
      
      
      
    
  

继承层次

RadioButtonGroup isn’t a visual component, which is why it’s added to the fx:Declarations block (new to Flex 4)—where nonvisual components in MXML must go.

SESSION 13  Data-driven Spark components (Lists)

three data-driven components: List , DropDownList , and ButtonBar .

session13/src/Tester.mxml

the ButtonBar can be used for navigation in conjunction with view states, to create the functionality of the Halo TabNavigator  or Halo   ViewStack  plus   LinkBar  combination, in which only one container component is shown based on which button the user selects.

SESSION 14  FXG and MXML graphics—building a game
