Okay, finaly I don’t know why it wasn’t working but it is working again.. I just have had a lign in case the Button doesn’t have an icon defined :
// Fade Disabled Icon
if(this.getStyle(”icon”) != null) {
DisplayObject(this.getChildByName(”disabledIcon”)).alpha = 0.4;
}

Hi !
I tryed to use your component, but when the Button is at the beginning disabled, strangely it is displayed as enabled when lauching the application.. So it doesn’t think to work fine yet..

@Glen

Thanks for the comment.

I have updated the IconButton component to fix this issue.

This is a neat trick; thanks for publishing it.

At runtime, I had immediately received “TypeError: Error #1009: Cannot access a property or method of a null object reference.” on the line that sets the alpha in the IconButton class.

It turns out that if I have a button whose default initial state is enabled, the error occurs. If I make the button’s default initial state disabled and enable the button later, the error goes away; that’s certainly an easy enough workaround for my needs.

I hope this helps someone if they run into the same issue.

Thanks
