A radiobuttons item is used to place a set of radio buttons on the rollout, only one of which can be checked at a time. The user can click different buttons in the set to change states.
The syntax is:
radiobuttons <name> [ <caption> ] labels:<array_of_strings> [default:<number>] [columns:<number>]
The default alignment of radiobuttons items is #center.
radiobuttons copy_type labels:#("copy", "instance", "reference")
radiobuttons which_obj labels:obj_name_array -- computed label array
on copy_type changed state do ...
copyfn = case copy_type.state of
An array of strings that specifies the number of radio buttons and the text label for each one.
The number of the radio button initially selected. Default is 1.
When set to 0, none of the radio buttons will be selected.
Number of columns across in which to arrange the buttons. By default, MAXScript will attempt to lay out all the radio buttons side-by-side on one line, and if they won't fit, vertically in a single column. You can force the layout system to array the buttons in multiple columns using this parameter. Each column is given the same width, which is the width of the widest label in all columns and it left-adjusts the radio buttons in these columns.
The number of the currently selected radio button in the order specified in the labels: array, or 0 if none is selected.
