How to change Numeric Stepper value by keyboard input

[foq]

Help please!

I hope you can save me on this one:

How can I actually change the Numeric Stepper value by entering a number via keyboard without having to press enter or click another Numeric Stepper?

I've tried everything, including keyboard events, but had no success.

All I want is, as soon as I type a number, the numeric stepper value changes to it.

Any ideas?

Thank you so much!

Here's one way...

stage.addEventListener(KeyboardEvent.KEY_UP, keyUsed);

function keyUsed(event:KeyboardEvent)
{
  if(event.charCode >= 48 && event.charCode <= 57){
   stepper.value = event.charCode - 48;
  }
}

Thanks a lot Ned!

Unfortunaly, it only works correctly if the value is less than 10, since it only captures the last KeyboardEvent. Plus, since I have more than one Numeric Stepper, it would change all of them at the same time (although I could look for which one is on focus.. hum.. and maybe only then capture the keys into a string... I could try that).

Thanks a lot for the pointers!

I anticipated you wanting more than you described, but you need to make sure your stepper has a maximum sufficient to handle the values you might expect to enter.

stage.addEventListener(KeyboardEvent.KEY_UP, keyUsed);

var numBuilder:String = "";

function keyUsed(event:KeyboardEvent)
{
  if(event.charCode >= 48 && event.charCode <= 57){
   numBuilder += String(event.charCode - 48);
      stepper.value = Number(numBuilder);
  } else {
   numBuilder = "";
  }
}

As far as managing different steppers with the same code goes... good luck.  I don't think Flash has the ability to read minds yet and determine which stepper you are thinking of when a key is pressed.  Anyway, you have a solution for what you initially asked for.

Thanks a lot for your help. I have actually dismissed the numeric stepper component and made my own, using buttons and text field. It worked better for me.

Again, thanks for your help and code!
