charLimit

Type: Integer Fields: Text Access: R/W

This property limits the number of characters that a user can type into a text field.

defaultValue

Type: String Fields: All but Button Access: R/W

This property exposes the default value of a field. This is the value that the field is set to when

the form is reset.

delay

Type: Boolean Fields: All Access: R/W

This property delays the redrawing of a field’s appearance. It is generally used to buffer a

series of changes to the properties of the field before requesting that the field regenerate its

appearance. Setting the property to true forces the field to wait until delay is set to false.The

update of its appearance then takes place, redrawing the field with its latest settings.

// Get the MyCheckBox field

var f = this.getField("MyCheckBox");

// set the delay and change the fields properties

// to beveled edge and medium thickness line.

f.delay = true;

f.borderStyle = border.b;

f.strokeWidth = 2;

// force the changes now

f.delay = false;

There is a corresponding document level delay flag if changes are being made to many fields at

once.
