StyleableTextField  - AS3 Flex

Specifies whether the text is editable, true, or not, false.

預設值為 true if type is TextFieldType.INPUT, otherwise false.。

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 the component, you should also set the value of the mouseEnabled property to false.

Indicates whether the component can receive focus when tabbed to. You can set focusEnabled to false when a component is used as a subcomponent of another component so that the outer component becomes the focusable entity. If this property is false, focus is transferred to the first parent that has focusEnable set to true.

預設值為 true。

The horizontal scroll position of the text.

Indicates whether the text has been truncated, true, or not, false.

Controls word wrapping within the text. This property corresponds to the lineBreak style.

Text may be set to fit the width of the container (LineBreak.TO_FIT), or can be set to break only at explicit return or line feed characters (LineBreak.EXPLICIT).

Legal values are flashx.textLayout.formats.LineBreak.EXPLICIT, flashx.textLayout.formats.LineBreak.TO_FIT, and flashx.textLayout.formats.FormatValue.INHERIT.

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 minimum 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 depends on 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 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.

The active, or last clicked position, of the selection. If the implementation does not support selection anchor this is the last character of the selection.

The anchor, or first clicked position, of the selection. If the implementation does not support selection anchor this is the first character of the selection.

Storage for the inline inheriting styles on this object. This CSSStyleDeclaration is created the first time that the setStyle() method is called on this component to set an inheriting style. Developers typically never need to access this property directly.

The class style used by this component. This should be an IStyleClient.

The text displayed by this text component.

The formatting of this text is controlled by CSS styles. The supported styles depend on the subclass.

預設值為 ""。

The vertical scroll position of the text.

Constructor.

Appends the specified text to the end of the text component, as if you had clicked at the end and typed.

An insertion point is then set after the new text. If necessary, the text will scroll to ensure that the insertion point is visible.

參數

Commit the styles into the TextField. This method must be called before the text is displayed, and any time the styles have changed. This method does nothing if the styles have already been committed.

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.

參數

Inserts the specified text into the text component as if you had typed it.

If a range was selected, the new text replaces the selected text. If there was an insertion point, the new text is inserted there.

An insertion point is then set after the new text. If necessary, the text will scroll to ensure that the insertion point is visible.

參數

Scroll so the specified range is in view.

參數

Selects all of the text.

Selects a specified range of characters.

If either position is negative, it will deselect the text range.

參數

Set focus to this text field.

Sets a style property on this component instance.

This can override a style that was set globally.

Calling the setStyle() method can result in decreased performance. Use it only when necessary.

參數

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

Truncate text to make it fit horizontally in the area defined for the control, and append an ellipsis, three periods (...), to the text. This function only works for single line text.
