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.

explicitHeight | 屬性 |
explicitHeight:Number
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | 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.
預設值為 NaN。

explicitMinHeight:Number
[唯讀] 語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | Flash Player 10, AIR 1.5 |
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.

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

It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by

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.

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.

語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | 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()

invalidateDisplayList | () | 方法 |
public function invalidateDisplayList():void
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | 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.

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.

public function move(x:Number, y:Number):void
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | 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.
參數
x:Number — Left position of the component within its parent.

Sizes the object.
Unlike directly setting the width

properties, calling the setActualSize()
method
does not set the explictWidth

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

public function styleChanged(styleProp:String):void
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | 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.
參數
styleProp:String — The name of the style property, or null if all styles for this
component have changed.

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.
