"This is a demo of the Motif Internationalized Extended List widget.\n\
\n\
The Internationalized Extended List provides multi-column list \n\
capabilities, which are not available in Motif. It uses XmStrings \n\
exclusively, and is able to display color pixmaps in the leftmost \n\
column. Search capability is built into the widget and is accessed \n\
through the Find Area below the list.\n\
\n\
Selections may be done in single select mode or extended select mode.\n\
There are convenience routines for selecting and unselecting rows \n\
programmatically as well. To see some of the features of this widget, \n\
add some data to the list, by selecting one of the players from the \n\
Add Player option menu.\n\
\n\
The Extended List can sort rows based on the currently selected column \n\
using sort routines provided by the developer. Select different\n\
column titles to see what order that sort routine produces. \n\
\n\
Search the list by typing a string into the text field next \n\
to the Find button. Then select the Find button or hit \n\
the Enter key to initiate the search. If the string is found, the \n\
row that contains it will be made viewable and selected. If not \n\
found,the Extended list will issue a beep.\n\
\n\
The Find area may be unmanaged by setting the \"showFind\" resource \n\
to False.See how the widget looks without the Find area taking up space.\n\
\n\
There is a convenience routine for unselecting rows programmatically \n\
Select the Unselect Current pushbutton to see it work.\n\
\n\
To see how the firstRow and firstCol resources work, select the \n\
Row 2, Col 1 button. The extended list will make that the upper left \n\
row and column. Remember, the list cannot be scrolled past its end. \n\
Therefore, if making a particular row and col the upper leftmost would \n\
cause the list to scroll past its boundaries, it will scroll to the \n\
end ",
