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

Whether the component can accept user interaction. After setting the enabled property to false, some components still respond to mouse interactions such as mouseOver. As a result, to fully disable UIComponents, you should also set the value of the mouseEnabled property to false. If you set the enabled property to false for a container, Flex dims the color of the container and of all of its children, and blocks user input to the container and to all of its children.

The explicitly specified height for the component, in pixels, as the component's coordinates. If no height is explicitly specified, the value is NaN.

Number that specifies the maximum height of the component, in pixels, as the component's coordinates.

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

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

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

The explicitly specified width for the component, in pixels, as the component's coordinates. If no width is explicitly specified, the value is NaN.

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

Number that specifies the maximum height of the component, in pixels, as the component's coordinates.

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

The measured height of this object.

This is typically hard-coded for graphical skins because this number is simply the number of pixels in the graphic. For code skins, it can also be hard-coded if you expect to be drawn at a certain size. If your size can change based on properties, you may want to also be an ILayoutManagerClient so a measure() method will be called at an appropriate time, giving you an opportunity to compute a measuredHeight.

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

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

Number that specifies the height of a component as a percentage of its parent's size. Allowed values are 0 to 100.

Number that specifies the width of a component as a percentage of its parent's size. Allowed values are 0 to 100.

A reference to the SystemManager object for this component.

Used by EffectManager. Returns non-null if a component is not using the EffectManager to execute a Tween.

Parameters

Parameters

Parameters

Call getCompatibleIUIComponent when you need to work with an IUIComponent that reports width, height, min, max, explicit, measured, etc. in post-scale coordinates.

Parameters

Returns the specified constraint value.

Parameters

Initialize the object.

Calling this method results in a call to the component's validateDisplayList() method before the display list is rendered.

For components that extend UIComponent, this implies that updateDisplayList() is called.

Calling this method results in a call to the component's validateProperties() method before the display list is rendered.

For components that extend UIComponent, this implies that commitProperties() is called.

Calling this method results in a call to the component's validateSize() method before the display list is rendered.

For components that extend UIComponent, this implies that measure() is called, unless the component has both explicitWidth and explicitHeight set.

Parameters

Moves this object to the specified x and y coordinates.

Parameters

Parameters

Sets the actual size of this object.

This method is mainly for use in implementing the updateDisplayList() method, which is where you compute this object's actual size based on its explicit size, parent-relative (percent) size, and measured size. You then apply this actual size to the object by calling setActualSize().

In other situations, you should be setting properties such as width, height, percentWidth, or percentHeight rather than calling this method.

Parameters

Sets the specified constraint value.

Parameters

Parameters

Validates and updates the properties and layout of this object by immediately calling validateProperties(), validateSize(), and validateDisplayList(), if necessary.

When properties are changed, the new values do not usually have an immediate effect on the component. Usually, all of the application code that needs to be run at that time is executed. Then the LayoutManager starts calling the validateProperties(), validateSize(), and validateDisplayList() methods on components, based on their need to be validated and their depth in the hierarchy of display list objects.

For example, setting the width property is delayed, because it may require recalculating the widths of the object's children or its parent. Delaying the processing also prevents it from being repeated multiple times if the application code sets the width property more than once. This method lets you manually override this behavior.
