Checkboxes and radio buttons in Igor Pro

The same control does both: a shared mode makes a group exclusive.

Function AddChecks()
    CheckBox smoothChk, pos={16, 160}, title="Smooth first", value=1
    CheckBox smoothChk, proc=OptionToggled

    CheckBox linRadio, pos={16, 182}, title="Linear", value=1, mode=1
    CheckBox logRadio, pos={96, 182}, title="Log", value=0, mode=1
End

Function OptionToggled(STRUCT WMCheckboxAction &cba) : CheckBoxControl
    if (cba.eventCode != 2)
        return 0
    endif

    Printf "%s is %s\r", cba.ctrlName, SelectString(cba.checked, "off", "on")
    return 0
End

How it works

1. value= is 0 or 1; variable= binds it to a global instead.
2. mode=1 turns a set of checkboxes into radio buttons.
3. The action's checked field is what changed.
