Any methods that you need to provide for access to the TextField should be defined in the component. If complete access to the TextField is needed, it might be easier to define the TextField as a public property. However, it may be convenient for the component to be notified whenever the properties of the TextField are accessed or altered.

Take a look at this in practice:. Recipe 1. You want to set font information for a range of text without using HTML text. Use the TextRange class to set properties for a range of characters. The TextRange class accepts a component that has a TextField within it, a parameter to indicate whether the component will be modified by the properties set in the TextRange object, and then two integers to determine the beginning and end of the range of characters in the TextField.

The TextRange object is constructed as follows:. The properties of the TextRange object affect the component that is passed in. In the following example, the color and the letter spacing of the user-selected area are set when the check box is selected:. This is the only required attribute. All the others simply control the layout of the image in relation to the text around it. Specifies the horizontal alignment of the embedded image within the text field.

Valid values are left and right. The default value is left. Specifies the amount of horizontal space containing no text that surrounds the image. The default value is 8. Specifies the amount of vertical space that surrounds the image. The default vspace value is 8. You want to create a TextArea in which a user can search and to highlight text the user enters into a TextInput.

Use the flash. TextField object and set the alwaysShowSelection property to true. Then use the setSelection method to set the index and length of the selected text.

TextArea component needs to have its focus set in order to display text selections. To work around this, you can create a subclass of the TextArea component so you can access the flash. TextField that the TextArea contains:. Setting the alwayShowSelection property to true means that the TextField will show a selection whether or not it has focus.

Now when the setSelection method is called, the TextField within the TextArea component will display and the TextArea will automatically scroll correctly to show the selection. Use the getCharBoundaries method to return the actual height, width, and x, y position of the character in the TextField. Then create a bitmap from the TextField that contains the desired character.

The getCharBoundaries method returns a rectangle that describes the x and y position as well as the height and width of the character index within a TextField. You can use this information to create a bitmap of the character, preserving all of its visual information, and animate those bitmaps. The key to the process is this code snippet:. This information is used to create the flash. BitmapData object that will appear in the bitmap object when it is created.

The BitmapData object accepts four parameters in its constructor:. Now that you have the bitmap object, create the Matrix object to store information about the particular part of the TextField that you want to capture, namely, the area of the TextField bounded by the rectangle returned by the getCharBoundaries method.

This Matrix is passed to the BitmapData draw method, which grabs the actual pixel data from the DisplayObject passed in. The rest of the example takes care of looping through the characters in the TextField , performing the preceding operation for each character, and then animating each new bitmap object created:.

This lets you simply pass the TextFormat object to the TextField you create to use in your bitmap manipulation and read directly from the TextField for the getCharBoundaries method.
