This command toggles the display of file names in a tree buffer. If file name display is switched on, the names of the files containing the class declaration are shown to the right of the class names. If the file is not known, the string ‘unknown’ is displayed.
This command is also provided in the tree buffer’s context menu.
Display file names for the current line, or for the number of lines given by a prefix argument.
Here is an example of a tree buffer with file names displayed.
| Collection (unknown) | IndexedCollection (indexedcltn.h) | Array (array.h) | FixedArray (fixedarray.h) | Set (set.h) | Dictionary (dict.h)
