PyGTK: Copy a file to clipboard (paste it in Nautilus)

dan — Thu, 04 Dec 2008 10:21:13 +0000

PyGTK provide clipboard functionality for standard targets: text, file(s) and image. Nautilus if does not use the standard URI target for copy/cat/paste file because this target does not provide the desired action (copy or cut).

For copy/cat/paste Nautilus use a special clipboard target named “x-special/gnome-copied-files”. The content of this target is a text with items separated by new line character (“\n”). The first line is the action (“copy” or “cut”) and then one URI per line.

To copy the file /path/abc.txt the target “x-special/gnome-copied-files” contains the text:

copy
file:///path/abc.txt

The class “gtk.Clipboard” has the method

def set_with_data(targets, get_func, clear_func, user_data)

to set the content of the clipboard to any targets and to provide functions for clipboard requests (get/clean).

Using this method I write a simple code to handle copy path to clipboard (gnomeclipboardtools.py):

PyGTK: Get GNOME icon associated with a file

If in your application you need to display a list of files/folders it would be nice to display icons near filenames.

Icons are associated with files using mime types. For a file you need to get it’s mime and the get the icon associated with this mime.
The module gnomevfs provides almost all you need:

def gnomevfs.get_mime_type(uri)

Returns a string containing the mime type (ex: for the file “file.tar.gz” the mime is “application/x-compressed-tar”).

def gnomevfs.mime_get_icon(mime_type)

Returns a string with an icon name.

I said almost because gnomevfs.mime_get_icon always returns None (at least in my version).

Since the gnomevfs.get_mime_type works fine I decide to write a little class to associate the mime with the icons.

Gnome use icon names like “gnome-mime-”. Ex: for the mime “application/x-compressed-tar” the gnome icon name is “gnome-mime-application-x-compressed-tar”.

My class try to associate the mime with an icon, by searching for icons with the name:

“gnome-mime-”
if the path is a directory it will try the icon name “folder” and if “folder” don’t exists just returns gtk.STOCK_DIRECTORY
“mime-”
returns gtk.STOCK_FILE

In order to optimize mime to icon association the class use a cache.
