public indent : Number
An integer that indicates the indentation from the left margin to the first character in the paragraph. The default value is null, which indicates that the property is undefined.
The following example creates a text field and sets the indentation to 10:
this.createTextField("mytext",1,100,100,100,100);
mytext.multiline = true;
mytext.wordWrap = true;
mytext.border = true;
var myformat:TextFormat = new TextFormat();
myformat.indent = 10;
mytext.text = "this is my first text field object text";
mytext.setTextFormat(myformat);
