The UIFTETextField class is an alternative to the UITextField class
for displaying text in MX components.
UIFTETextField extends FTETextField in the same way
that UITextField extends TextField.
By extending FTETextField, it makes it possible
for MX components to use the Flash Text Engine.
Benefits of using FTE over TextField include
higher-quality typography, bidirectional text, and rotatable text.
When MX components use FTE, they can use the same
embedded fonts as Spark components, which always use FTE.
Otherwise, a font must be embedded with embedAsCFF="false"
for use by TextField-based components, and with
embedAsCFF="true" for use by FTE-based components.
MX components that display text use the textFieldClass
style to determine whether to create instances
of UITextField or UIFTETextField.
They are able to use either class because both classes implement
the IUITextField interface.
Warning: if UIFTETextField inherits layoutDirection="rtl", it
will modify its own transform.matrix to restore the default
coordinate system locally.

This value generally corresponds to the rendered appearance of the
object and should be usable for correlating the identifier with
the object as it appears visually within the application.
This method has been implemented in FTETextField
to simply return a copy of the defaultTextFormat,
because FTETextField does not support formatting a range.

Runtime Versions :
Flash Player 10, AIR 1.5
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.

Number that specifies the maximum height of the component,
in pixels, in the component's coordinates, if the maxHeight property
is set. Because maxHeight is read-only, this method returns NaN.
You must override this method and add a setter to use this
property.
The default value is NaN.
Implementation public function get explicitMaxHeight():Number
Number that specifies the maximum width of the component,
in pixels, in the component's coordinates, if the maxWidth property
is set. Because the maxWidth property is read-only, this method returns NaN.
You must override this method and add a setter to use this
property.
The default value is NaN.
Implementation public function get explicitMaxWidth():Number
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,

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

maxHeight
property
maxHeight:Number [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 :

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

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

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.

Setting the height or explicitHeight properties
resets this property to NaN.
This property returns a numeric value only if the property was
previously set; it does not reflect the exact size of the component
in percent.
This property is always set to NaN for the UITextField control.
When used with Spark layouts, this property is used to calculate the
height of the component's bounds after scaling and rotation. For example
if the component is rotated at 90 degrees, then specifying
percentHeight will affect the component's width.

getExplicitOrMeasuredHeight
()
method
public function getExplicitOrMeasuredHeight():Number
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
A convenience method for determining whether to use the
explicit or measured height
Returns
Number — A Number which is explicitHeight if defined
or measuredHeight if not.
getExplicitOrMeasuredWidth
()
method
public function getExplicitOrMeasuredWidth():Number

getStyle
()
method
public function getStyle(styleProp:String):*
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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():TextFormat
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
Returns the TextFormat object that represents
character formatting information for this UITextField object.
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
UITextFormat — An object that contains formatting information for 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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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.

public function move(x:Number, y:Number):void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
Returns true if the child is parented or owned by this object.
Parameters
child:DisplayObject — The child DisplayObject.
Returns
Boolean — true if the child is parented or owned by this UITextField object.
public function parentChanged(p:DisplayObjectContainer):void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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
Boolean — true if a replay was successful.
setActualSize
()
method
public function setActualSize(w:Number, h:Number):void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
Does nothing.
A UITextField cannot have inline styles.
Parameters
styleProp:String — n/a
value:* — n/a
setVisible
()
method
public function setVisible(visible:Boolean, noEvent:Boolean = false):void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
Sets the visible property of this UITextField object.
Parameters
visible:Boolean — true 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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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 4
Runtime Versions :
Flash Player 10, AIR 1.5
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
Boolean — true if the text needed truncation.
validateNow
()
method
public function validateNow():void
Language Version :
ActionScript 3.0
Product Version :
Flex 4
Runtime Versions :
Flash Player 10, AIR 1.5
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.
