[flexcoders] Re: Text Area question
Thanx Gordon,
I have tried this example and it solves many of my problems but how
ever there is one little thing that is very strange.When I'm typing
fast my cursor is slower than appearance of the letters.And it's
constantly rises.
Any thoughts or solution?

Below is an example of forcing text input to uppercase as the user
types
it.
The trick is to handle the 'textInput' event, which is dispatched
after
the user presses a key but before the new text appears in the
TextArea
(or TextInput, or TextField). This is a cancelable event, which
means
that you can call event.preventDefault() to prevent the system from
doing the default handling of this event;. For this event, calling
preventDefault() means that the TextArea won't process the
keystroke.
Instead you process it yourself by uppercasing it, inserting it in
the
appropriate place in the TextArea's text string, and setting the
insertion point to be after the new uppercase character.

I have tried
item.text = item.text.toUpperCase().and implemented on textArea
component but is seems to change all previous typing to upperCase
and that wasn't my need.I need to be able to change case when I
type
new line.Maybe the other solution will help but I hope that there
is
some other easier way to do that.
If You have some idea please type it.

If you need to ensure that everything they type is in all CAPS,
then
just set the text value like this:
item.text = item.text.toUpperCase(). Or another possible way is
to
listen on the keypress and convert it as they press. I guess you
could
also listen on the change event and convert it then, but it

be a

Hope that helps some, feel free to reply back if you need more

it.

Thanks man I have tried that class (flash.ui.Keyboard) and there is capsLock public Property but I can't force capsLock press.Here is my code: import flash.ui.Keyboard; var test:Keyboard = new Keyboard(); test.capsLock = true; I'm getting error:Access to possibly undefined property capsLock if You see any error or You can give me any instruction that will be nice --- In flexcoders@yahoogroups.com, camlinaeizerous [EMAIL PROTECTED] wrote: To set the left and right margins you can use the paddingLeft and paddingRight properties. For the capslock question you can use keyboardEvents to detect certain key but i'm not sure how to force an emulated keypress, there is a flash.ui.Keyboard class that may be able to do what you want but I havn't played with it at all. --- In flexcoders@yahoogroups.com, brankosli brankosli@ wrote: I will be more that thankful if someone could solve my problem.I'm working with textArea component and I have 2 questions: I need to know if there is any possibility to fix left and right margin in textArea component?
