The window options are used to control the characteristics of the GWM window and to override the default values. These must be set before the window is created with GWM_CRWIN. A logical option has two values, true or false. A true value means select the option, a false value is equivalent to accepting the default. The ’INTERACTIVE’ option is an example of a logical option.
