Flex Data Binding

// Task.

Package

{

Public class task

{

[Bindable]

Public VaR _ name: string;

Public Function task (Name: string)

{

_ Name = Name;

}

}

}

 

 

// Mxml

 

 

Private VaR _ sum: Int = 0;

[Bindable]

Private var task: task = new task ("FX: script ");

 

[Bindable]

Public Function get sum (): int

{

Return _ sum;

}

 

Public Function set sum (value: INT): void

{

_ Sum = value;

}

 

 

<S: textinput x = "422" Y = "116" id = "inputone" text = "{task. _ name}">

<S: Label x = "62" Y = "49" width = "137" Height = "27" text = "{sum}" id = "label"/>

 

The object member must be declared as [Bindable], the object must also be declared as [Bindable], and then bind data.

The getter/setter function can be declared as [Bindable] or bound to Data,

 

<S: textinput id = "inputone" text = "@ {inputtwo. Text}"/>
<S: textinput id = "inputtwo"/>
The text = "@ {inputtwo. Text}" in the Code implements bidirectional binding.

<FX: binding source = "inputone. Text" Destination = "inputtwo. Text" twoway = "true"/>
Twoway = "true" indicates two-way binding.
