Restrict chars property

hi,

sorry if has been covered already, there property can set restrict characters entered in editable container? or have listen flowoperationevent , remove chars don't after they've been typed ... or there way.

 

thanks.

there no restrict chars property in tlf, there in flex gumbo components use tlf. may want @ using gumbo components. if doesn't work you, , want yourself, best way listen flowoperationend event, gets sent after operation has fired. check textlength of textflow there, , if it's on limit, call editmanager delete characters. undo single unit.

 

here's sketch @ how might look:

 

         textflow.addeventlistener(flowoperationevent.flow_operation_end,limitpaste,false,0,true);

 

          private function limitpaste(event:flowoperationevent):void

              {
                   if (textflow.textlength > maxflowlength)
                  {
                      var trimamt:int = textflow.textlength - maxflowlength;
                      var pasteend:int = pasteposition + (operation.absoluteend - operation.absolutestart);
                      textflow.interactionmanager.setselection(pasteend - trimamt, pasteend);
                      ( textflow.interactionmanager ieditmanager).deletenext();
                  }
              }

 

this not debugged code, should give idea how go ahead -- or can use gumbo.
