getSelected | () | method |
public function getSelected(beginIndex:int, endIndex:int):Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Returns a Boolean value that specifies whether a TextSnapshot object contains selected text in the specified range.
To search all characters, pass a value of 0 for start, and
charCount (or any very large number) for end.
To search a single character, pass the end parameter a value that is one greater
than the start parameter.
Parameters
beginIndex:int — Indicates the position of the first character to be examined.
Valid values for beginIndex are 0 through
TextSnapshot.charCount - 1. If beginIndex is a negative value,
0 is used.
| |
endIndex:int — A value that is one greater than the index of the last character to be examined. Valid values
for endIndex are 0 through charCount.
The character indexed by the endIndex parameter is not included in the extracted
string. If this parameter is omitted, charCount is used. If this value is less than
or equal to the value of beginIndex, beginIndex + 1 is used.
|
Boolean — A Boolean value that indicates whether at least one character in the given range has been
selected by the corresponding setSelected() method (true); otherwise,
false.

getSelectedText | () | method |
public function getSelectedText(includeLineEndings:Boolean = false):String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9., Flash Lite 4 |
Returns a string that contains all the characters specified by the corresponding
setSelected() method. If no characters are specified (by the
setSelected() method), an empty string is returned.
If you pass true for includeLineEndings,
newline characters are inserted in the return string, and
the return string might be longer than the input range. If
includeLineEndings is false or omitted, the method returns
the selected text without adding any characters.
Parameters
includeLineEndings:Boolean (default = false)false.
|
String — A string that contains all the characters specified by the
corresponding setSelected() command.

getText | () | method |
public function getText(beginIndex:int, endIndex:int, includeLineEndings:Boolean = false):String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9., Flash Lite 4 |
Returns a string that contains all the characters specified by the beginIndex
and endIndex parameters. If no characters are selected, an empty string is
returned.
To return all characters, pass a value of 0 for beginIndex and
charCount (or any very large number) for endIndex.
To return a single character, pass a value of beginIndex + 1 for endIndex.
If you pass a value of true for includeLineEndings,
newline characters are inserted in the string returned where deemed appropriate. In this case,
the return string might be longer than the input range. If includeLineEndings
is false or omitted, the selected text is returned without any characters added.
Parameters
beginIndex:int — Indicates the position of the first character to be included in the
returned string. Valid values for beginIndex are0 through
charCount - 1. If beginIndex is a negative value,
0 is used.
| |
endIndex:int — A value that is one greater than the index of the last character to be examined. Valid values
for endIndex are 0 through charCount. The character
indexed by the endIndex parameter is not included in the extracted string. If this
parameter is omitted, charCount is used. If this value is less than or
equal to the value of beginIndex, beginIndex + 1 is used.
| |
includeLineEndings:Boolean (default = false)true) or are not inserted (false) into the returned string.
The default value is false.
|
String — A string containing the characters in the specified range, or an empty string if no
characters are found in the specified range.

getTextRunInfo | () | method |
public function getTextRunInfo(beginIndex:int, endIndex:int):Array| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Returns an array of objects that contains information about a run of text. Each object corresponds to one character in the range of characters specified by the two method parameters.
Note: Using the getTextRunInfo() method for a large range of text can
return a large object. Adobe recommends limiting the text range defined by the
beginIndex and endIndex parameters.
Parameters
beginIndex:int — The index value of the first character in a range of characters in a TextSnapshot
object.
| |
endIndex:int — The index value of the last character in a range of characters in a TextSnapshot
object.
|
Array — An array of objects in which each object contains information about a specific character
in the range of characters specified by the beginIndex and endIndex parameters.
Each object contains the following eleven properties:

hitTestTextNearPos | () | method |
public function hitTestTextNearPos(x:Number, y:Number, maxDistance:Number = 0):Number| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9., Flash Lite 4 |
Lets you determine which character within a TextSnapshot object is on or near the specified
x, y coordinates of the movie clip containing the text in the TextSnapshot object.
If you omit or pass a value of 0 for maxDistance, the location specified
by the x, y coordinates must lie inside the bounding box of the TextSnapshot object.
This method works correctly only with fonts that include character metric information; however,
by default, the Flash authoring tool does not include this information for static text fields.
Therefore,
the method might return -1 instead of an index value. To ensure that an index
value is returned, you can force the Flash authoring tool to include the character metric
information for a font. To do this, add a dynamic text field that uses that font, select
Character Options for that dynamic text field, and then specify that font outlines should be
embedded for at least one character. (It doesn't matter which characters you specify, nor
whether they are the characters used in the static text fields.)
Parameters
x:Number — A number that represents the x coordinate of the movie clip containing the
text.
| |
y:Number — A number that represents the y coordinate of the movie clip containing the
text.
| |
maxDistance:Number (default = 0)x, y that can be searched for
text. The distance is measured from the center point of each character. The
default value is 0.
|
Number — A number representing the index value of the character that is nearest to the specified
x, y coordinate. Returns
-1 if no character is found, or if the font doesn't contain character metric information.

setSelectColor | () | method |
public function setSelectColor(hexColor:uint = 0xFFFF00):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9., Flash Lite 4 |
Specifies the color to use when highlighting characters that have been selected with the
setSelected() method. The color is always opaque; you can't specify a
transparency value.
This method works correctly only with fonts that include character metric information; however,
by default, the Flash authoring tool does not include this information for static text fields.

Parameters
hexColor:uint (default = 0xFFFF00)setSelected() command, expressed in hexadecimal
format (0xRRGGBB).

setSelected | () | method |
public function setSelected(beginIndex:int, endIndex:int, select:Boolean):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9., Flash Lite 4 |
Specifies a range of characters in a TextSnapshot object to be selected or deselected.
Characters that are selected are drawn with a colored rectangle behind them, matching the
bounding box of the character. The color of the bounding box is defined by
setSelectColor().
To select or deselect all characters, pass a value of 0 for beginIndex and
charCount (or any very large number) for endIndex. To
specify a single character, pass a value of start + 1 for endIndex.
Because characters are individually marked as selected, you can call this method multiple times to select multiple characters; that is, using this method does not deselect other characters that have been set by this method.
The colored rectangle that indicates a selection is displayed only for fonts that include character metric information; by default, Flash does not include this information for static text fields. In some cases, this behavior means that text that is selected won't appear to be selected onscreen. To ensure that all selected text appears to be selected, you can force the Flash authoring tool to include the character metric information for a font. To do this, add a dynamic text field that uses that font, select Character Options for that dynamic text field, and then specify that font outlines should be embedded for at least one character. It doesn't matter which characters you specify, nor even if they are the characters used in the static text fields in question.
Parameters
beginIndex:int — Indicates the position of the first character to select.
Valid values for beginIndex are 0 through charCount - 1.
If beginIndex is a negative value, 0 is used.
| |
endIndex:int — An integer that is 1+ the index of the last character to be
examined. Valid values for end are 0 through charCount.
The character indexed by the end parameter is not included in the extracted
string. If you omit this parameter, TextSnapshot.charCount is used. If the
value of beginIndex is less than or equal to the value of endIndex,
beginIndex + 1 is used.
| |
select:Boolean — A Boolean value that specifies whether the text should be selected (true)
or deselected (false).
