Example
The following example illustrates how you can output the number of characters in a specified
TextSnapshot object. To use this code, create a static text field that contains the text
“TextSnapshot Example”.
// this example assumes that the movie clip contains
// the static text "TextSnapshot Example"
var my_mc:MovieClip = this;
var my_snap:TextSnapshot = my_mc.getTextSnapshot();
var count:Number = my_snap.getCount();
var theText:String = my_snap.getText(0, count, false);
trace(count); // output: 20
trace(theText); // output: TextSnapshot Example

Usage
my_snap.getSelected(from:Number, to:Number) : Boolean
Parameters
from
An integer that indicates the position of the first character of my_snap to be examined.
Valid values for
from are 0 through TextSnapshot.getCount() - 1. If from is a negative value,
0 is used.
to An integer that is 1+ the index of the last character in my_snap to be examined. Valid values
for
to are 0 through TextSnapshot.getCount(). The character indexed by the to parameter is
not included in the extracted string. If this parameter is omitted,
TextSnapshot.getCount() is
used. If this value is less than or equal to the value of
from, from+1 is used.
Returns
A Boolean value of true, if at least one character in the given range has been selected by the
corresponding
TextSnapshot.setSelected() command, false otherwise.
Description
Method; 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
from and TextSnapshot.getCount() (or any very
large number) for
to. To search a single character, pass a value of from+1 for to.
