text overflow in left side if we set the textAlign as "right" for spark textinput control?

if i use a textinput with

textAlign="right"

when text is more than it can fit into, text is overflown, 开发者_JAVA百科i want to hide text and not to over flow from right side.. and scroll the text using cursor(with left and right key) is possible if yes how ?

by using skin, i am able to clip the overflow.. but now cursor is not scrolling to left side.

text overflow in left side if we set the textAlign as "right" for spark textinput control?

any solution ?


to understand your problem I did the same that you did. So i added a textInput with a skinclass.

<s:TextInput id="io" skinClass="com.carsa.rumbo.cobros.ui.skin.io" text="123456789 10 11 12 13 14 15 16 17 18 19 20"/>

and to see aall the properties of a textInput skin, you can choose textinput as hostcomponent class in the creation of skin. I tried it this way and works as I think you wanted.

This is the skin code:
