WIDGET COMMAND

pathName add ?arg...?: Add a button to the button box of the dialog box. Default -command option is Dialog::enddialog $path index where index is number of button added.

pathName cget option: Returns the current value of the configuration option given by option. Option may have any of the values accepted by the creation command.

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. 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 creation command. Read-only options are not be modified.

pathName draw ?focus?: This command draw the Dialog, and set grab to it following modal option. If modal option is set to none, the command returns immediatly an empty string. In all other case, the command returns when Dialog::enddialog is called or when Dialog is destroyed. The return value is the result argument of Dialog::enddialog or -1 if it is destroyed.
By default, the focus is set to the default button referenced by default option, or to the toplevel of Dialog if no default button has been set. If focus is present, it must be a pathname, or an index to a button. Initial focus is set on this pathname or corresponding button.

pathName enddialog result: This command is typically called within a command of a button to make Dialog::draw return.

pathName getframe: Returns the pathname of the user window.

pathName invoke index: Invoke the Button given by index.

pathName itemcget index option: Returns the current value of a configuration option for the item. Option may have any of the values accepted by the item creation command.

pathName itemconfigure index ?option? ?value option value ...?: This command is similar to the configure command, except that it applies to the options for an individual item, whereas configure applies to the options for the widget as a whole. Options may have any of the values accepted by the item creation widget command. If options are specified, options are modified as indicated in the command and the command returns an empty string. If no options are specified, returns a list describing the current options for the item. Read-only options are not be modified.

pathName setfocus index: Set the focus to the Button given by index.
