There is no default value for this. If you do not specify any buttons, no buttons will be displayed. This button is highlighted. If no default button is specified, then the first element of the array whose reference is passed to the -buttons option is used as the default. Add the widget indicated by widget .
Options are the options that the widget accepts.
The widget is advertized as a subwidget of DialogBox . Display the dialog box, until user invokes one of the buttons in the bottom frame. Returns the name of the button invoked. There is no way of removing a widget once it has been added to the top frame. There is no control over the appearance of the buttons in the bottom frame nor is there any way to control the placement of the two frames with respect to each other e.g. widgets to the left, buttons to the right instead of widgets on the top and buttons on the bottom always.
