ScriptNumericUpDown

This feature is new in Q 4.8.

ScriptNumericUpDown

Represents a number-entry box into that also has up and down arrow buttons. The control is created by the RuleForm object's newNumericUpDown() function. Use setMinimum() and setMaximum() to change the constraints for number entry. Use setIncrement() to control the change triggered by the up and down arrow buttons.

getValue()

Retrieves the number entered.

Returns:

The number entered, or (if set) the default. If no default has been provided and nothing has been entered then this will return null.

isExpression

Use this to control whether the item should be treated as an expression or as a string in R code. Only applicable to textBox, comboBox and dropBox controls.

lineBreakAfter

Use this where your Rule has many controls, and they do not fit comfortably in a single line. It allows you to specify that a new row will be started after this control.

Example:

c.lineBreakAfter = true;
