Question

I want to build a textinput that adapts itself from the maxchars value of its textdisplay.

I tried to override the init function of the component like this:

override protected function initializationComplete():void{
   if(this.textDisplay.maxChars != 0){
      this.maxWidth = this.textDisplay.maxChars*10;
      super.initializationComplete();
   }
}

But it doesn’t work at all. How can I code this?

Answer 1

Thats already there in s:textinput property named widthInChars
set that value to maxChars value like this

Im mxml

<s:TextInput id="txtName" widthInChars="{txtName.maxChars}" maxChars="23" />

In as

txtName.widthInChars = txtName.maxChars;

Try this
I hope this might help you.
