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.
Warning: if UITextField inherits layoutDirection="rtl", it
will modify its own transform.matrix to restore the default
coordinate system locally.

explicitHeight | property |
explicitHeight:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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.

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

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

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.

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

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

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.

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.

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 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().

initialize | () | method |
public function initialize():void| Language Version: | ActionScript 3.0 |

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 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.

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.

| 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.

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: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 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)null, a localizable string
such as "..." will be used.
|
Boolean — true 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.
