headers

Arguments: list-view

Returns the value of the headers property of the argument. The value can be t (have headers) or nil ( do not have headers). A header is a row of column headers, each using the column title as its title. Headers are typically mouse-sensitive. Clicking on a header sorts the contents of the control alphabetically according to the entries in the clicked column.

The headers property may not be changed on an existing control, and must instead be specified with the inspector when designing a control (using a form) or with the :headers initarg of make-instance. (It can be changed using the inspector when designing a form but not for a running control, either in the IDE or in an application.)

See the list-view class/control.
