Abstract

Disclosed is a design that provides a multi-line listbox control that allows compound commands to be grouped, viewed, and selected as a single entry. Regular list boxes are well suited to atomic entries, but are difficult to use when the list contains compound entries. This design can be implemented within the framework of the current listbox control.

Multi-line Listbox Control for Compound Entries

       Disclosed is a design that provides a multi-line listbox
control that allows compound commands to be grouped, viewed, and
selected as a single entry.  Regular list boxes are well suited to
atomic entries, but are difficult to use when the list contains
compound entries. This design can be implemented within the framework
of the current listbox control.

      Conventional list boxes are geared to single entries, such as
choosing a name from a list, but when an entry consists of multiple
objects, such as a group of commands (like GRANT X, GRANT Y, REVOKE
Z), that should be treated as a single object, the significance and
size of the entry can be lost on the user.  This is because the
compound entry looks like a single entry and the entire compound
entry may not fit in the space available on the list.

      Instead of forcing the user or programmer to use a single line,
compound entries should be able to span across multiple lines. For
example, when a command expands from one entry to three, the first
line of the command is not indented, but the second and following
line for the compound command are with an arrow mark to show that
they belong to the first line.  The user should be able to control
whether the compound object is placed in one entry or spanned across
more than one by selecting the entry with a mouse button and/or key
combination.  Performing this combination again on the same entry
would re...
