The List component displays list-based information and is ideally suited for the display of arrays of information.

The List component consists of items, rows, and a data provider, which are described as follows:

Item: An ActionScript object that usually contains a descriptive label property and a data property that stores the data associated with that item.
Row: A component that is used to display the item.
Data provider: A component that models the items that the List component displays.

By default, the List component uses the CellRenderer class to supply the rows in which list items are displayed. You can create these rows programmatically; this is usually done by subclassing the CellRenderer class. The CellRenderer class implements the ICellRenderer interface, which provides the set of properties and methods that the List component uses to manipulate its rows and to send data and state information to each row for display. This includes information about data sizing and selection.

The List component provides methods that act on its data provider--for example, the addItem() and removeItem() methods. You can use these and other methods to manipulate the data of any array that exists in the same frame as a List component and then broadcast the changes to multiple views. If a List component is not provided with an external data provider, these methods automatically create an instance of a data provider and expose it through the List.dataProvider property. The List component renders each row by using a Sprite that implements the ICellRenderer interface. To specify this renderer, use the List.cellRenderer property. You can also build an Array instance or get one from a server and use it as a data model for multiple lists, combo boxes, data grids, and so on.

Property Detail

iconField

property

iconField:String

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the item field that provides the icon for the item.

Note: The iconField is not used if the iconFunction property is set to a callback function.

The default value is "icon".

Implementation
public function get iconField():String
public function set iconField(value:String):void

Example ( How to use this example )

The following example creates a list with an icon for each item. A symbol named RedBox must exist in the library and have "Export for ActionScript" toggled in its symbol properties:

import fl.data.DataProvider;
import fl.controls.List;

var dp:DataProvider = new DataProvider();
dp.addItem( { iconSource:RedBox, label:"Item 1" } );
dp.addItem( { iconSource:RedBox, label:"Item 2" } );
dp.addItem( { iconSource:RedBox, label:"Item 3" } );

var list:List = new List();
list.iconField = "iconSource";
list.dataProvider = dp;
addChild(list);

iconFunction

property

iconFunction:Function

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the function to be used to obtain the icon for the item.

Note: The iconField is not used if the iconFunction property is set to a callback function.

The default value is null.

Implementation
public function get iconFunction():Function
public function set iconFunction(value:Function):void

Example ( How to use this example )

The following example uses the iconFunction property to provide an icon to a limited number of items in a list. A symbol named RedBox must exist in the library and have "Export for ActionScript" toggled in its symbol properties for this example to function correctly:

import fl.data.DataProvider;
import fl.controls.List;

var dp:DataProvider = new DataProvider();
dp.addItem( { label:"Item 1" } );
dp.addItem( { label:"Item 2" } );
dp.addItem( { label:"Item 3" } );

var list:List = new List();
list.iconFunction = determineIcon;
list.dataProvider = dp;
addChild(list);

function determineIcon(item:Object):String {
    if(item.label == "Item 2") {
        return "RedBox";
    }
    else {
        return null;
    }
}

labelField

property

labelField:String

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the name of the field in the dataProvider object to be displayed as the label for the TextInput field and drop-down list.

By default, the component displays the label property of each dataProvider item. If the dataProvider items do not contain a label property, you can set the labelField property to use a different property.

Note: The labelField property is not used if the labelFunction property is set to a callback function.

The default value is "label".

Implementation
public function get labelField():String
public function set labelField(value:String):void

Related API Elements

labelFunction

Example ( How to use this example )

The following example displays each item in a list with the abbreviatedLabel property rather than the default label property:

import fl.data.DataProvider;
import fl.controls.List;

var dp:DataProvider = new DataProvider();
dp.addItem( { abbreviatedLabel:"NY", label:"New York" } );
dp.addItem( { abbreviatedLabel:"CA", label:"California" } );
dp.addItem( { abbreviatedLabel:"WA", label:"Washington" } );
dp.addItem( { abbreviatedLabel:"CT", label:"Connecticut" } );
dp.addItem( { abbreviatedLabel:"VT", label:"Vermont" } );

var list:List = new List();
list.setSize(40,100);
list.labelField = "abbreviatedLabel"
list.dataProvider = dp;
addChild(list);

labelFunction

property

labelFunction:Function

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the function to be used to obtain the label for the item.

By default, the component displays the label property for a dataProvider item. But some data sets may not have a label field or may not have a field whose value can be used as a label without modification. For example, a given data set might store full names but maintain them in lastName and firstName fields. In such a case, this property could be used to set a callback function that concatenates the values of the lastName and firstName fields into a full name string to be displayed.

Note: The labelField property is not used if the labelFunction property is set to a callback function.

The default value is null.

Implementation
public function get labelFunction():Function
public function set labelFunction(value:Function):void

Example ( How to use this example )

This example sets the labelFunction property of a list to a function that formats the string to be displayed in each cell:

import fl.data.DataProvider;
import fl.controls.List;

var myDataProvider:DataProvider = new DataProvider();
myDataProvider.addItem({name:"User A", price:0.43});
myDataProvider.addItem({name:"User B", price:0.34});

var users:List = new List();
users.dataProvider = myDataProvider;
users.labelFunction = myLabelFunction;
addChild(users);

function myLabelFunction(item:Object):String {
    return  item.name + " ($" + item.price.toFixed(2) + ")";
}

rowCount

property

rowCount:uint[override]

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the number of rows that are at least partially visible in the list.

Implementation
override public function get rowCount():uint
override public function set rowCount(value:uint):void

Example ( How to use this example )

This example sets the size of a list and determines the number of potentially visible rows by tracing the rowCount property:


import fl.data.DataProvider;
import fl.controls.List;

var dp:DataProvider = new DataProvider();
var i:uint;
for(i=0; i<100; i++) {
    dp.addItem( { label: "Item " + i } );
}

var list:List = new List();
list.setSize(100,300);
list.dataProvider = dp;
addChild(list);

trace(list.rowCount); // 15

The following example sets the size of a List component using the rowCount based on the current value of a slider:


import fl.controls.Slider;
import fl.controls.List;
import fl.data.DataProvider;
import fl.events.SliderEvent;

var dp:DataProvider = new DataProvider();
var i:int;
for (i=0; i<8; i++) {
    dp.addItem({label:"Item " + i});
}

var mySlider:Slider = new Slider();
mySlider.move(10, 10);
mySlider.tickInterval = 1;
mySlider.snapInterval = 1;
mySlider.minimum = 2;
mySlider.maximum = 9;
mySlider.liveDragging = true;
mySlider.addEventListener(SliderEvent.CHANGE, changeHandler);
addChild(mySlider);

var myList:List = new List();
myList.dataProvider = dp;
myList.move(mySlider.x, mySlider.y + 20);
myList.setSize(100, 50);
addChild(myList);

function changeHandler(event:SliderEvent):void {
    myList.rowCount = event.value;
}

rowHeight

property

rowHeight:Number

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

Gets or sets the height of each row in the list, in pixels.

The default value is 20.

Implementation
public function get rowHeight():Number
public function set rowHeight(value:Number):void

Retrieves the default style map for the current component. The style map contains the type that is appropriate for the component, depending on the style that the component uses. For example, the disabledTextFormat style contains a value of null or a TextFormat object. You can use these styles and call setStyle() on the current component. The following code overrides the default disabledTextFormat style on the specified component:

componentInstance.setStyle("disabledTextFormat", new TextFormat());

Returns

Object — Default styles object.
