Hi Latcho,
I see you've gotten a couple response but I'll throw another one in to
the mix. The main functions that will interest you are:
1) getCharIndexAtPoint which locates the char at the edge of the
textfield
2) replaceSelectedText which is used to substitute in "..."
This is some code ripped out of a class I use that extends TextField
and does a bunch of things for me, one of which is the truncation of
text. It is not complete but should give you an idea for approaching
this problem.
private var _htmlText:String = ""; //holds the complete text for the
field even when truncation occurs
private var _tempText:TextField = new TextField();; //another
textField which is used to truncate the text and then place it into
this actual field
private var _gutterCompensation:Number = -5; // -5 compensates for the
gutter on either side of the text
private function checkDimensions(){
_htmlText = super.htmlText;
if(super.textWidth > width - _gutterCompensation){
//use the temporary text holder to do the text shortening and replacing
_tempText.htmlText = _htmlText;
_tempText.defaultTextFormat = super.defaultTextFormat; //this ensures
that the "..." are placed using the correct formatting
//find the character located at the edge of the text then count back
2 more characters and replace everything from there to the end with
"..."
_tempText.setSelection(super.getCharIndexAtPoint(width-
_gutterCompensation, 2)-2, super.text.length);
_tempText.replaceSelectedText("...");
super.htmlText = _tempText.htmlText;
}
Again is this an email/modified version so it is not complete just to
give you ideas. (I don't remember if I really needed to use
super.htmlText or could have gotten by with just this.htmlText)
Basically what I do is when the text field looses focus after editting
I run the checkDimensions function which does my truncation but also
stores the complete text. When the user brings the textfield back in
to focus I replace the truncated text with the complete text I have
stored.

Any suggestions (AS3)
