Dialog System - how to highlight more than one item in a List Box

Problem:

Dialog System -

How are multiple lines of data items highlighted in a List Box control?

Resolution:

Set the Selection Type to control how the list items are selected at run time.

Select Single so that only a single list item can be selected in the list box.

Select Multiple so that more than one item can be selected in the list box. The user must click the mouse over each item in turn.

Select Extended so that more than one item can be selected in the list box. The user must click the mouse and drag it over the items to be selected.

The GET-LIST-ITEM-STATE function can then be used to determine which items have been selected.
