Change font/color of TextInput?

Is there a quick and easy way to change the font/color of a component like the TextInput or Checkbox? I’m able to change the TextField with a TextFormat, but seem to run into a square peg and round hole with the other components.

var tf:TextFormat = new TextFormat();
tf.font = “Verdana”;
tf.color = 0x000000;
tf.size = 10;
tf.underline = false;
var id_lbl:TextField = new TextField();
id_lbl.defaultTextFormat = tf;

Can I plug this into a Checkbox to change the label or TextInput to change the text?
