|

|
|
* - vfs aka File name+link: clickable filename, with evtl. clickable path-components
|
|
* - vfs-size aka File size: human readable filesize, eg. 1.4k
|
|
* - vfs-mode aka File mode: posix mode as string eg. drwxr-x---
|
|
* - vfs-mime aka File icon: mime type icon or thumbnail (if configured AND enabled in the user-prefs)
|
|
* - vfs-uid aka File owner: Owner of file, or 'root' if none
|
|
* - vfs-gid aka File group: Group of file, or 'root' if none
|
|
*
|
|
* All widgets accept as value a full path.
|
|
* vfs-mime and vfs itself also allow an array with values like stat (incl. 'path'!) as value.
|
|
* vfs-mime also allows just the mime type as value.
|
|
* All other widgets allow additionally the nummeric value from the stat call (to not call it again).
