Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
In theory, the TextLines are parented by the RichEditableText which is a child of TextArea. The TextLine API uses the term “Atom” instead of “character” because it can theoretically have images and other non-character things taking up space in the line. I’m not sure TextFlowComposer will help you unless you need to re-compose the TextFlow because you changed it enough. Things like strikethrough are done by drawing directly in the TextLine. If I were to do quick-and-dirty highlighting, I would start by applying child shapes and blendmodes.

Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
Highlights are just graphics drawn into the TextLines. The TextLines should be children of the RichEditableText and you can use TextLine APIs to find atom/character positions.

Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
Hey Thanks Ian, I was just looking at that actually but TextInput doesn't seem to have it (Flex 4). I read that you can use: import mx.core.mx_internal; use namespace mx_internal; to access TextField and then getCharBoundaries() but that doesn't seem to work in Flex 4. Any ideas?

Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
Oh - sorry, should have said - you'll need to get at the .textField property of (for example) your mx.controls.Text object, which will give you back the raw flash.text.TextField for you to then call getCharBoundaries() on it. Unfortunately, .textField is a protected property of mx.controls.Text, so can't be seen from outside the class. The simplest way to get at it is to extend mx.controls.Text - build your own component that inherits from Text. That will give you access to the .textField property you need; then you can call methods on it as appropriate.

Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
Take a look at flash.text.TextField.getCharBoundaries() (and other TextField methods). HTH, Ian On Mon, Aug 31, 2009 at 8:53 PM, Baz wrote: > > > Anyone know how to get the X/Y coordinates of a specific character/letter in > a text field or text input? > > Thanks! > >

Anyone know how to get the X/Y coordinates of a specific character/letter in a text field or text input? Thanks!
