Determines the baseline y-coordinate of the first line of text of the component. Any subclass of UITextField should override this property.

The name of this instance's class, such as "DataGridItemRenderer".

This string does not include the package name. If you need the package name as well, call the getQualifiedClassName() method in the flash.utils package. It will return a string such as "mx.controls.dataGridClasses::DataGridItemRenderer".

A reference to the document object associated with this UITextField object. A document object is an Object at the top of the hierarchy of a Flex application, MXML component, or AS component.

A Boolean value that indicates whether the component is enabled. This property only affects the color of the text and not whether the UITextField is editable. To control editability, use the flash.text.TextField.type property.

The default value is true.

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.

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.

The default value is NaN.

Number that specifies the maximum 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 maxWidth with respect to its parent is affected by the scaleX property.

The default value is NaN.

Number that specifies the minimum 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 minHeight with respect to its parent is affected by the scaleY property.

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

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

A single Sprite object that is shared among components and used as an overlay for drawing focus. Components share this object if their parent is a focused component, not if the component implements the IFocusManagerComponent interface.

If true, the paddingLeft and paddingRight styles will not add space around the text of the component.

The default value is true.

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.

Specifies whether this component is included in the layout of the parent container. If true, the object is included in its parent container's layout. If false, the object is positioned by its parent container as per its layout rules, but it is ignored for the purpose of computing the position of the next child.

The beginning of this UITextField's chain of inheriting styles. The getStyle() method accesses inheritingStyles[styleName] to search the entire prototype-linked chain. This object is set up by the initProtoChain() method. You typically never need to access this property directly.

A flag that determines if an object has been through all three phases of layout validation (provided that any were required)

Number that specifies the maximum 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 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 will be set to UIComponent.DEFAULT_MAX_HEIGHT.

Depth of this object in the containment hierarchy. This number is used by the measurement and layout code. The value is 0 if this component is not on the DisplayList.

The beginning of this UITextField's chain of non-inheriting styles. The getStyle() method accesses nonInheritingStyles[styleName] method to search the entire prototype-linked chain. This object is set up by the initProtoChain() method. You typically never need to access this property directly.

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.

The parent container or component for this component.

Number that 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.

Set to true after the createChildren() method creates any internal component children.

The class style used by this component. This can be a String, CSSStyleDeclaration or an IStyleClient.

If this is a String, it is the name of a class declaration in an mx: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 ojbect are used by this component.

Returns the SystemManager object used by this component.

Text to display in the ToolTip.

Array of properties that are currently being tweened on this object.

Used to alert the EffectManager that certain properties of this object are being tweened, so that the EffectManger doesn't attempt to animate the same properties.

A flag that determines if an object has been through all three phases of layout validation (provided that any were required)

Constructor.

A convenience method for determining whether to use the explicit or measured height

A convenience method for determining whether to use the explicit or measured width

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 may 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 will know its type and will 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() will be 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 static method StyleManager.isValidStyleValue() to test whether the value was set.

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().

Initializes this component.

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

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.

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.

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.

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.

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, you should 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.

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

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

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 may 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.

Sets the font color of the text.

Sets the focus to this component. The component may 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.

Does nothing. A UITextField cannot have inline styles.

Sets the visible property of this UITextField object.

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.

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

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 may 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.
