flash as3 adding focus listener to an input text field

What you want to do is check if the user is highlighting or if the box was already highlighted since last focus, and if not, stop flash player from putting the carat at the location clicked with event.preventDefault() function, and then set selection from beginning to end. Event.preventDefault() is a sneaky little function you call right on the event object in your event handler, and it prevents whatever the default actions would be for that event (in this case, clear selected text and place carat)

as3 code example:

// assuming you have a textbox input called _myTextInputBox

import flash.events.FocusEvent;
import flash.events.MouseEvent;
import flash.text.TextField;

_myTextInputBox.addEventListener(MouseEvent.CLICK, onClickTextBox);
_myTextInputBox.addEventListener(FocusEvent.FOCUS_OUT, onTextBoxLoseFocus);

var _highlightTextOnClick:Boolean = true;

function onClickTextBox(e:Event):void {

var didUserHighlight:Boolean = Boolean(e.target.selectionBeginIndex != e.target.selectionEndIndex);

if ( _highlightTextOnClick && !didUserHighlight) {
e.preventDefault();
e.target.setSelection(0, e.target.text.length);
_highlightTextOnClick = false;
}

}

function onTextBoxLoseFocus(e:FocusEvent):void
{
_highlightTextOnClick = true;
}

Hello,

Select the input text, push Ctrl+F3 to open the (Properties) panel, look for (Paragraph) then (Behavior) click the drop-down menu beside it, choose (Multiline). and you're good to go.
