public static getBeginIndex() : Number
Returns the index at the beginning of the selection span. If no index exists or no text field currently has focus, the method returns -1. Selection span indexes are zero-based (for example, the first position is 0, the second position is 1, and so on).
Availability: ActionScript 1.0; Flash Player 5
Number - An integer.
The following example creates a text field at runtime, and sets its properties. A context menu item is added that can be used to change the currently selected text to uppercase characters.
this.createTextField("output_txt", this.getNextHighestDepth(), 0, 0, 300, 200);
output_txt.multiline = true;
output_txt.wordWrap = true;
output_txt.border = true;
output_txt.type = "input";
output_txt.text = "Enter your text here";
var my_cm:ContextMenu = new ContextMenu();
my_cm.customItems.push(new ContextMenuItem("Uppercase...", doUppercase));
function doUppercase():Void {
var startIndex:Number = Selection.getBeginIndex();
var endIndex:Number = Selection.getEndIndex();
var stringToUppercase:String = output_txt.text.substring(startIndex, endIndex);
output_txt.replaceText(startIndex, endIndex, stringToUppercase.toUpperCase());
}
output_txt.menu = my_cm;
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player 7 or later. If your SWF file includes a version 2 component, use the version 2 components' DepthManager class instead of the MovieClip.getNextHighestDepth() method.
For another example, see the Flash Samples page at www.adobe.com/go/learn_fl_samples. Download and decompress the Samples zip file and go to the ActionScript2.0\Strings folder to access the Strings.fla file.
