Applets scritte in python per l'ambiente desktop Gnome

Maria Susana Diaz | 11:38 |
Le gDeskLets sono delle applets scritte in python per l'ambiente desktop Gnome.

Sono essenzialmente composte da due parti: il sensore, e il display.
Il primo funge da iterazione tra l'utente e le applets, mentre il secondo è il file
che dà un aspetto grafico alle applets. Sia sensori che applets sono reperibili al
sito: http://gdesklets.org

Come installare le applets del desktop

Per instalare il programma:
sudo apt-get install gdesklets
sudo apt-get install gdesklets-data

Per installare le suddette applets ho preferito utilizzare i precompilati Slackware in modo da rendere l'operazione veloce ed intuitiva anche per gli utenti che sono entrati nel mondo GNU/Linux solo da poco.

Per gli utenti che utilizzano swaret come tools per installare programmi,se hanno inserito il repository del sito www.slacky.it nel file di configurazione di swaret (swaret.conf),basta aprire una shell e lanciare da root il comando : swaret --install gdesklets ... in questo modo si scarica il file e lo si installa in automatico.

Per chi non utilizza swaret può reperire il file precompilato (*.tgz) dal sito www.slacky.it , una volta scaricato il file apriamo la solita shell,logghiamoci come root ed installiamo il pacchetto con il comando : installpkg

Se invece vogliamo installare il programma di gestione dai sorgenti è possibile reperire i file al seguente link:

scaricati i sorgenti apriamo la shell logghiamoci come root:

* prima cosa da fare decomprimere il pacchetto con il comando

tar xvzf nome-pacchetto.tar.gz se l'archivio è in formato tar.gz
#:oppure tar xvjf nome-pacchetto.tar.bz2 se l'archivio è in formato tar.bz2

* seconda cosa posizionamoci all'interno della cartella decompressa ed eseguiamo il processo di compilazione ed installazione dando in seguenza i seguenti comandi :

./configure make make install (questo da root).

Per far si che il programma funzioni sarà oppurtuno risolvere le varie dipendenze che esso comporta. Sul sito

http://www.pycage.de/software_gdesklets.html

viene fornito un elenco delle eventuali dipendeze che riporto qui:

* Python 2.2 or higher
* pygtk 2.0.0 or higher
* libgtop2
* librsvg
* Gconf
* gnome-python 2.0.0 or higher
* GConf support for gnome-python (extra package gnome-python2-gconf on Redhat Linux)
* some sensors may have extra requirements

Tutti i vari pacchetti che eventualmente mancano si possono scaricare dal repository del sito www.slacky.it .

A questo punto si avrà nel nostro sistema installato il demone che ci permette di installare e partire le varie applet.

Per farlo partire andiamo nel menù Applicazioni -->Accessori e clicchiamo sulla voce gDesklets. Avremo a video la gDesklets Shell.
Come installare le applet del desktop (aDesklets)

Il fratello minore aDesklets non ha la stessa popolarità e non ha lo stesso numero de desklets disponibili ma gode di una straordinaria leggerezza e bellezza grafica, oltre che della totale indispendenza del x-window manager (gnome, kde, fluxbox, xfce, ecc.)

Per installare il programma:

sudo apt-get install adesklets

dopo di che, digitate adesklets_installer, per far comparire una piccola interfaccia grafica, attraverso la quale potete installare le vostre adesklets. Una descrizione di esse potete trovarla sempre sul sito ufficiale.
All’avvio dell’installer potrebbe comparire un messaggio del genere :

Traceback (most recent call last): File "/usr/bin/adesklets_installer", line 631, in ? Con soldomik si risolve il problema. Basta infatti installare il pacchetto pythontk, con questo comando : comprensivo di librerie.
sudo apt-get install python-tk
