Implements IAutomationObject, IIMESupport, IFlexModule, IInvalidating, ISimpleStyleClient, IToolTipManagerClient, IUITextField
Subclasses AdvancedDataGridItemRenderer, DataGridItemRenderer

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The UITextField class defines the component used by many Flex components to display text. For example, the mx.controls.Button control uses a UITextField component to define the label area of the Button control.

The UITextField class extends the flash.text.TextField class to support additional functionality required by Flex, such as CSS styles, invalidation/measurement/layout, enabling/disabling, tooltips, and IME (Input Method Editor) support for entering Chinese, Japanese, and Korean text.

Styles

Styles are either common or associated with a specific theme. If the style is common, it can be used with any theme. If a style is associated with a specific theme, it can only be used if your application uses that theme.

Common Styles
 Style Description Defined By
  
color
Type: uint Format: Color CSS Inheritance: yes
Color of text in the component, including the component label. The default value for the Halo theme is 0x0B333C. The default value for the Spark theme is 0x000000.
UITextField
  
direction
Type: String CSS Inheritance: yes
The directionality of the text displayed by the component.

The allowed values are "ltr" for left-to-right text, as in Latin-style scripts, and "rtl" for right-to-left text, as in Arabic and Hebrew.

FTE and TLF use this value in their bidirectional text layout algorithm, which maps Unicode character order to glyph order.

Note: This style only applies when an MX component specifies UIFTETextField as its textFieldClass.

The direction also affects the alignment of the text within the bounds of the TLFTextField. It does not, however, affect the the placement of the TLFTextField within the component.

The default value is "ltr".
UITextField
  
disabledColor
Type: uint Format: Color CSS Inheritance: yes
Color of text in the component if it is disabled. The default value is 0xAAB3B3.
UITextField
  
fontAntiAliasType
Type: String CSS Inheritance: yes
Sets the antiAliasType property of internal TextFields. The possible values are "normal" (flash.text.AntiAliasType.NORMAL) and "advanced" (flash.text.AntiAliasType.ADVANCED).

The default value is "advanced", which enables advanced anti-aliasing for the font. Set to "normal" to disable the advanced anti-aliasing.

This style has no effect for system fonts.

This style applies to all the text in a TextField subcontrol; you cannot apply it to some characters and not others.

The default value is "advanced".

Number that specifies the explicit height of the component, in pixels, in the component's coordinates.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true explicitHeight with respect to its parent is affected by the scaleY property.

Setting the height property also sets this property to the specified height value.



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

explicitMaxHeight

explicitMinHeight

property 
explicitMinHeight:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The minimum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.

Application developers typically do not set the explicitMinHeight property. Instead, they set the value of the minHeight property, which sets the explicitMinHeight property. The value of minHeight does not change.

At layout time, if minHeight was explicitly set by the application developer, then the value of explicitMinHeight is used. Otherwise, the value of measuredMinHeight is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true minHeight with respect to its parent is affected by the scaleY property.



Implementation
    public function get explicitMinHeight():Number

explicitMinWidth

property

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The minimum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.

Application developers typically do not set the explicitMinWidth property. Instead, they set the value of the minWidth property, which sets the explicitMinWidth property. The value of minWidth does not change.

At layout time, if minWidth was explicitly set by the application developer, then the value of explicitMinWidth is used. Otherwise, the value of measuredMinWidth is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true minWidth with respect to its parent is affected by the scaleX property.



Implementation
    public function get explicitMinWidth():Number

explicitWidth

property 
explicitWidth:Number

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Number that specifies the explicit width of the component, in pixels, in the component's coordinates.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true explicitWidth with respect to its parent is affected by the scaleX property.

Setting the width property also sets this property to the specified width value.



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

focusPane

imeMode

property 
imeMode:String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Specifies the IME (input method editor) mode. The IME enables users to enter text in Chinese, Japanese, and Korean. Flex sets the specified IME mode when the control gets the focus, and sets it back to the previous value when the control loses the focus.

The flash.system.IMEConversionMode class defines constants for the valid values for this property. You can also specify null to specify no IME.

The default value is null.



Implementation
    public function get imeMode():String

maxHeight

property 
maxHeight:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The maximum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.

The component developer uses this property to set an upper limit on the height of the component.

If the application developer overrides the default value of maxHeight, the new value is stored in explicitMaxHeight. The default value of maxHeight does not change. As a result, at layout time, if maxHeight was explicitly set by the application developer, then the value of explicitMaxHeight is used for the component's maximum recommended height. If maxHeight is not set explicitly by the user, then the default value is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true maxHeight with respect to its parent is affected by the scaleY property. Some components have no theoretical limit to their height. In those cases their maxHeight is set to UIComponent.DEFAULT_MAX_HEIGHT.



Implementation
    public function get maxHeight():Number

maxWidth

property 
maxWidth:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The maximum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.

The component developer uses this property to set an upper limit on the width of the component.

If the application developer overrides the default value of maxWidth, the new value is stored in explicitMaxWidth. The default value of maxWidth does not change. As a result, at layout time, if maxWidth was explicitly set by the application developer, then the value of explicitMaxWidth is used for the component's maximum recommended width. If maxWidth is not set explicitly by the user, then the default value is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true maxWidth with respect to its parent is affected by the scaleX property. Some components have no theoretical limit to their width. In those cases their maxWidth is set to UIComponent.DEFAULT_MAX_WIDTH.



Implementation
    public function get maxWidth():Number

measuredHeight

minHeight

property 
minHeight:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The minimum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.

If the application developer sets the value of minHeight, the new value is stored in explicitMinHeight. The default value of minHeight does not change. As a result, at layout time, if minHeight was explicitly set by the application developer, then the value of explicitMinHeight is used for the component's minimum recommended height. If minHeight is not set explicitly by the application developer, then the value of measuredMinHeight is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true minHeight with respect to its parent is affected by the scaleY property.



Implementation
    public function get minHeight():Number

minWidth

property 
minWidth:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The minimum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.

If the application developer sets the value of minWidth, the new value is stored in explicitMinWidth. The default value of minWidth does not change. As a result, at layout time, if minWidth was explicitly set by the application developer, then the value of explicitMinWidth is used for the component's minimum recommended width. If minWidth is not set explicitly by the application developer, then the value of measuredMinWidth is used.

This value is used by the container in calculating the size and position of the component. It is not used by the component itself in determining its default size. Thus this property may not have any effect if parented by Container, or containers that don't factor in this property. Because the value is in component coordinates, the true minWidth with respect to its parent is affected by the scaleX property.



Implementation
    public function get minWidth():Number

nonZeroTextHeight:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Unlike textHeight, this returns a non-zero value even when the text is empty. In this case, it returns what the textHeight would be if the text weren't empty.



Implementation
    public function get nonZeroTextHeight():Number

owner

property 
owner:DisplayObjectContainer

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

By default, set to the parent container of this object. However, if this object is a child component that is popped up by its parent, such as the dropdown list of a ComboBox control, the owner is the component that popped up this object.

This property is not managed by Flex, but by each component. Therefore, if you use the PopUpManger.createPopUp() or PopUpManger.addPopUp() method to pop up a child component, you should set the owner property of the child component to the component that popped it up.

The default value is the value of the parent property.

Number — A Number which is explicitWidth if defined or measuredWidth if not.

getStyle

()method 
public function getStyle(styleProp:String):*

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Gets a style property that has been set anywhere in this component's style lookup chain.

This same method is used to get any kind of style property, so the value returned can be a Boolean, String, Number, int, uint (for an RGB color), Class (for a skin), or any kind of object. Therefore the return type is simply specified as *.

If you are getting a particular style property, you know its type and often want to store the result in a variable of that type. No casting from * to that type is necessary.

var backgroundColor:uint = getStyle("backgroundColor");

If the style property has not been set anywhere in the style lookup chain, the value returned by getStyle() is undefined. Note that undefined is a special value that is not the same as false, "", NaN, 0, or null. No valid style value is ever undefined. You can use the method IStyleManager2.isValidStyleValue() to test whether the value was set.

Parameters

styleProp:String — Name of the style property.

Returns
* — Style value.

getTextStyles

()method 
public function getTextStyles():flash.text:TextFormat

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Returns the TextFormat object that represents character formatting information for this UITextField object.

Returns
flash.text:TextFormat — A TextFormat object.

getUITextFormat

()method 
public function getUITextFormat():mx.core:UITextFormat

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Returns a UITextFormat object that contains formatting information for this component. This method is similar to the getTextFormat() method of the flash.text.TextField class, but it returns a UITextFormat object instead of a TextFormat object.

The UITextFormat class extends the TextFormat class to add the text measurement methods measureText() and measureHTMLText().

Returns
mx.core:UITextFormat — An object that contains formatting information for this component.

initialize

()method 
public function initialize():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Initializes this component.

This method is required by the IUIComponent interface, but it actually does nothing for a UITextField.

invalidateDisplayList

()method 
public function invalidateDisplayList():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Marks a component so that its updateDisplayList() method gets called during a later screen update.

Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the width and height, it would be wasteful to update the component immediately after you change the width and then update again with the new height. It is more efficient to change both properties and then render the component with its new size once.

Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

invalidateProperties

()method 
public function invalidateProperties():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Marks a component so that its commitProperties() method gets called during a later screen update.

Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text color and size, it would be wasteful to update the color immediately after you change it and then update the size when it gets set. It is more efficient to change both properties and then render the text with its new size and color once.

Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

invalidateSize

()method 
public function invalidateSize():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Marks a component so that its measure() method gets called during a later screen update.

Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text and font size, it would be wasteful to update the text immediately after you change it and then update the size when it gets set. It is more efficient to change both properties and then render the text with its new size once.

Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

move

()method 
public function move(x:Number, y:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Moves the component to a specified position within its parent. Calling this method is exactly the same as setting the component's x and y properties.

If you are overriding the updateDisplayList() method in a custom component, call the move() method rather than setting the x and y properties. The difference is that the move() method changes the location of the component and then dispatches a move event when you call the method, while setting the x and y properties changes the location of the component and dispatches the event on the next screen refresh.

Parameters

x:Number — Left position of the component within its parent.
 
y:Number — Top position of the component within its parent.

owns

()method 
public function owns(child:DisplayObject):Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Returns true if the child is parented or owned by this object.

Parameters

child:DisplayObject — The child DisplayObject.

Returns
Booleantrue if the child is parented or owned by this UITextField object.

parentChanged

()method 
public function parentChanged(p:DisplayObjectContainer):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

This function is called when a UITextField object is assigned a parent. You typically never need to call this method.

Parameters

p:DisplayObjectContainer — The parent of this UITextField object.

replayAutomatableEvent

()method 
public function replayAutomatableEvent(event:Event):Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Replays the specified event. A component author should probably call super.replayAutomatableEvent in case default replay behavior has been defined in a superclass.

Parameters

event:Event — The event to replay.

Returns
Booleantrue if a replay was successful.

setActualSize

()method 
public function setActualSize(w:Number, h:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sizes the object. Unlike directly setting the width and height properties, calling the setActualSize() method does not set the explictWidth and explicitHeight properties, so a future layout calculation can result in the object returning to its previous size. This method is used primarily by component developers implementing the updateDisplayList() method, by Effects, and by the LayoutManager.

Parameters

w:Number — Width of the object.
 
h:Number — Height of the object.

setColor

()method 
public function setColor(color:uint):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sets the font color of the text.

Parameters

color:uint — The new font color.

setFocus

()method 
public function setFocus():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sets the focus to this component. The component can in turn pass focus to a subcomponent.

Note: Only the TextInput and TextArea controls show a highlight when this method sets the focus. All controls show a highlight when the user tabs to the control.

setStyle

()method 
public function setStyle(styleProp:String, value:*):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Does nothing. A UITextField cannot have inline styles.

Parameters

styleProp:String — Name of the style property.
 
value:* — New value for the style.

setVisible

()method 
public function setVisible(visible:Boolean, noEvent:Boolean = false):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sets the visible property of this UITextField object.

Parameters

visible:Booleantrue to make this UITextField visible, and false to make it invisible.
 
noEvent:Boolean (default = false)true to suppress generating an event when you change visibility.

styleChanged

()method 
public function styleChanged(styleProp:String):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Detects changes to style properties. When any style property is set, Flex calls the styleChanged() method, passing to it the name of the style being set.

This is an advanced method that you might override when creating a subclass of UIComponent. When you create a custom component, you can override the styleChanged() method to check the style name passed to it, and handle the change accordingly. This lets you override the default behavior of an existing style, or add your own custom style properties.

If you handle the style property, your override of the styleChanged() method should call the invalidateDisplayList() method to cause Flex to execute the component's updateDisplayList() method at the next screen update.

Parameters

styleProp:String — The name of the style property, or null if all styles for this component have changed.

truncateToFit

()method 
public function truncateToFit(truncationIndicator:String = null):Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Truncate text to make it fit horizontally in the area defined for the control, and append an ellipsis, three periods (...), to the text.

Parameters

truncationIndicator:String (default = null) — The text to be appended after truncation. If you pass null, a localizable string such as "..." will be used.

Returns
Booleantrue if the text needed truncation.

validateNow

()method 
public function validateNow():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Validate and update the properties and layout of this object and redraw it, if necessary. Processing properties that require substantial computation are normally not processed until the script finishes executing. For example setting the width property is delayed, because it can require recalculating the widths of the objects children or its parent. Delaying the processing prevents it from being repeated multiple times if the script sets the width property more than once. This method lets you manually override this behavior.
