+## @deftypefn  {Function File} @var{s} = zenity_list(@var{title}, @var{columns}, @var{data}, @var{options1}, ...)
+## Displays a graphical list of data.
+## The variable @var{title} sets the title of the list. The variable
+## @var{columns} must be a cell array of strings of length N containing the headers
+## of the list. The variable @var{data} must be cell array of strings of
+## length NxM containing the data of the list.
+##
+## The code
+## @example
+## zenity_list("Age versus Height", @{"Age", "Height"@}, 
+## @{"10", "20"; "120cm", "180cm"@})
+## @end example
+## produces a list of the data. The user can select a row in the table, and it's
+## first value will be returned by the function when the user closes the window.
+##
+## It's possible to alter the behaviour of the list window by passing more than
+## three arguments to the funtion. Theese optional string arguments can be
+## @table @samp
+## @item checklist
+## The first row in the list will be a check box. The first value of each data row
+## must be either "TRUE" or "FALSE".
+## @item radiolist
+## The first row in the list will be a radio list. The first value of each data row
+## must be either "TRUE" or "FALSE".
+## @item editable
+## The values of the list will be editable by the user.
+## @item A numeric value
+## The value returned by the function will be the value of this column
+## of the user selected row.
+## @item all
+## The value returned by the function will be the entire row selected by the user.
+## @end table
