That depends.. If you have a component-heavy application with your own custom styles for instance, it might be better to use a TextArea. Or you could take it a step further and make this into a new component (and even make it an mxp for distribution). Then again, if all you need is one (and one only) non-selectable textfield, sure grab a TextField and ScrollBar and move on :) I mearly wanted to present a better solution (IMO) than overlaying a TextArea with a shape, which is to actually fix what seems to be broke. regards, Muzak ----- Original Message ----- From: "Cor" <[email protected]> To: "'Flash Coders List'" <[email protected]> Sent: Sunday, March 29, 2009 1:00 PM Subject: RE: [Flashcoders] ?: how to prevent users to copy text from aTextArea? > Just interested. > Is all this worth the hassle? > I mean instead using a TextArea, I would go for a normal TextField and a > custom scrollbar all in 1 movieclip. > And set the needs. > > Cor. > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Muzak > Sent: zondag 29 maart 2009 1:20 > To: Flash Coders List > Subject: Re: [Flashcoders] ?: how to prevent users to copy text from > aTextArea? > > > The problem seems to be that TextArea uses the "enabled" value to set the > inner textField's selectable property value. > > protected function updateTextFieldType():void { > textField.type = (enabled && _editable) ?
