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:Number

explicitMinHeight:Number
[read-only]
Language Version : | ActionScript 3.0 |
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.

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.

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

Language Version : | ActionScript 3.0 |
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
.

maxHeight:Number
[read-only]
Language Version : | ActionScript 3.0 |
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:Number
[read-only]
Language Version : | ActionScript 3.0 |
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.

Language Version : | ActionScript 3.0 |
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.

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

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:DisplayObjectContainer
Language Version : | ActionScript 3.0 |
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.
Implementation public function get owner():DisplayObjectContainer

percentHeight:Number
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Specifies the height of a component as a percentage
of its parent's size. Allowed values are 0-100. The default value is NaN.
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.

or an IStyleClient.
If this is a String, it is the name of one or more whitespace delimited class
declarations in an <fx:Style>
tag or CSS file. You do not include the period
in the styleName
. For example, if you have a class style named ".bigText"
,
set the styleName
property to "bigText"
(no period).
If this is an IStyleClient (typically a UIComponent), all styles in the
styleName
object are used by this component.

|
public function getStyle(styleProp:String):*
Language Version : | ActionScript 3.0 |
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 public function getTextStyles():TextFormat
Language Version : | ActionScript 3.0 |

public function getUITextFormat():UITextFormat
Language Version : | ActionScript 3.0 |
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 | UITextFormat — An object that contains formatting information for this component.

public function initialize():void
Language Version : | ActionScript 3.0 |
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.
public function invalidateDisplayList():void
Language Version : | ActionScript 3.0 |
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.
public function invalidateProperties():void
Language Version : | ActionScript 3.0 |
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.
public function invalidateSize():void
Language Version : | ActionScript 3.0 |
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.
public function move(x:Number, y:Number):void
Language Version : | ActionScript 3.0 |
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.
|
public function owns(child:DisplayObject):Boolean
Language Version : | ActionScript 3.0 |
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.

public function parentChanged(p:DisplayObjectContainer):void
Language Version : | ActionScript 3.0 |
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.
|
public function replayAutomatableEvent(event:Event):Boolean
Language Version : | ActionScript 3.0 |
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 | Boolean — true if a replay was successful.
|
public function setActualSize(w:Number, h:Number):void
Language Version : | ActionScript 3.0 |
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.
|
public function setColor(color:uint):void
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Sets the font color of the text.
Parameters
| color:uint — The new font color.
|
public function setFocus():void
Language Version : | ActionScript 3.0 |
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.
public function setStyle(styleProp:String, value:*):void
Language Version : | ActionScript 3.0 |
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.
|
public function setVisible(visible:Boolean, noEvent:Boolean = false):void
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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.
|
public function styleChanged(styleProp:String):void
Language Version : | ActionScript 3.0 |
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.
|
public function truncateToFit(truncationIndicator:String = null):Boolean
Language Version : | ActionScript 3.0 |
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 | Boolean — true if the text needed truncation.
|
public function validateNow():void
Language Version : | ActionScript 3.0 |
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.
