/* AvContourList.cc
"Dialog" to allow user to configure contour information.
The buttons of the selection box are renamed to match their use here.
OK becomes Add Add an item from the text field to the list.
Accept becomes Delete
Delete the item in the text field from the list.
A Done button is added to signify that user is finished.
One would assume that the OK button would be used to signal a
return. However, it appears the widget is wired to also use this to
close the widget. Since the user is expected to be able to enter
multiple lines, another button had to be added. The "Add" button is
extraneous, since <RETURN> does this. However, it appears the button
is necessary for proper functioning, so we leave it.
Basically the same as AvListItem with some additions to handle contour
specific needs.
This version uses its own top level window.
