Command-Line Name: -buttonstate, Database Name: buttonstate, Database Class; -

In this state the disabledForeground and background options determine how the button is displayed.

Window Command

A Window created through the rtl_combobox command exposes various functions. Using these functions has the following general form:

          pathName option ?arg arg ...?

PathName is the same as the window path name. Option and the args determine the exact behavior of the command. The following commands are possible for this window:

pathName cget option

Returns the current value of the configuration option given by option. Option may have any of the values accepted by the rtl_combobox command.

pathName configure ?option? ?value option value ...?

Query or modify the configuration options of the window. 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 window 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 rtl_combobox command.
