A Toplevel Widget's Arguments

The toplevel command creates a new Tcl command whose name is the same as the path name of the toplevel's window. This command may be used to invoke various operations on the widget. It has the following general form:

 
pathName option ?arg arg ...?

PathName is the name of the command, which is the same as the toplevel widget's path name. Option and the args determine the exact behavior of the command. The following commands are possible for toplevel widgets:

pathName :configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option:value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the toplevel command.
