Ubuntu-gr Forum

Συνεχίζω το θέμα καθώς το εξέλιξα λίγο (λόγω φλασιάς !!! )

Κατά πρώτον πρόθεσα ένα κουμπάκι, το record για να το πατάμε και να γράφουμε, το stream που παίζει εκείνη τη στιγμή, ως stream.mp3

Κατά δεύτερον ανακάλυψα πως μπορείς να φτιάξεις δικό σου θέμα εμφάνισης.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Για το κουμπάκι πρόσθεσα κάποιες γραμμές στο αρχείο /usr/share/screenlets/Radio/RadioScreenlet.py

1. Κρατήστε ένα αντίγραφο του παραπάνω αρχείου και μετά αλλάξτε το κάνοντας αντιγραφή επικόληση τον παρακάτω κώδικα :

Επειδή το αρχείο είναι τεράστιο και οι αλλαγές ( οι προσθήκες ) που έκανα είναι σε διάφορα κομάτια του ( στην αρχή, μέση και τέλος του αρχικού αρχείου) , δεν μπορώ να τις δείξω εδώ.
Αν θέλετε όμως μπορείται να δείτε τις διαφορές εγκαθιστώντας το meld (εφαρμογή που συγκρίνει δύο αρχεία και καταδεικνύει τις διαφορές τους)

Κώδικας: Επιλογή όλων

sudo apt-get install meld

2. Κατεβάστε αυτά τα δύο εικονιδιάκια ή φτιάξτε δικά σας με το gimp ( Αφού τα δικά μου είναι για τα μπάζα ! )


ονομάστε το record.png


και

ονομάστε το record_press.png

3. Αντιγράψτε τα εικονιδιάκια στο φάκελο : /usr/share/screenlets/Radio/themes/default (ως root εννοείται)


4. Προσθέστε στο αρχείο theme.conf που είναι στη διεύθυνση /usr/share/screenlets/Radio/themes/default/theme.conf
τις παρακάτω γραμμές :

record_button_x = 150
record_button_y = 50
record_button_width = 32
record_button_height = 24

έτσι ώστε το αρχείο να .... καταντήσει έτσι :

Κάντε δεξί κλικ στο γαλάζιο εικονίδιο του Screenlet daemon (που βρίσκεται πάνω δεξιά στην περιοχή ειδοποιήσεων ( t r a y ) ) και ...
Restart all Screenlets

Θα πρέπει τώρα να βλέπετε και ένα τρίτο κουμπί. Πατήστε το και μετά από λίγο πατήστε stop. Θα έχει γραφτεί στον προσωπικό σας φάκελο το αρχείο stream.mp3. Ακούστε το και δείτε αν δουλεύει.

Όσο για το νέο θέμα εμφάνισης ....
Φτιάξτε δικό σας εύκολα ! Εγώ επειδή είμαι λίγο γκάου έκανα κάτι ώρες !

1. Φτιάξτε φάκελο στο /usr/share/screenlets/Radio/themes και ονομάστε τον όπως θέλετε να λέγεται το θέμα σας.
Αντιγράψτε τα εικονάκια όλα από τον φάκελο /usr/share/screenlets/Radio/themes/default και επεξεργαστείτε τα με το gimp ( με ψώφισε το άτιμο ! Αναρωτιέμαι αν υπάρχει άνθρωπος που το ξέρει απέξω ! ).

Ή κατεβάστε από το internet εικονιδιάκια που σας αρέσουν.
Τα κουμπιά (play.png stop.png record.png play_press.png stop_press.png και record_press.png) θα πρέπει να έχουν διαστάσεις 32Χ24 ( άντε δύο πάνω - δύο κάτω !!! )
Το logo.png είναι 200Χ80 και έχει διαφανές φόντο. Αν δεν ξέρετε καθόλου, δείτε λίγο αυτό : file:///usr/share/gimp/2.0/help/en/gimp-using-web-transparency.html (με τον firefox)

Εγώ άλλαξα τις πράσινες αυτές νότες με αυτό http://www.scsc.state.pa.us/scsc/lib/sc ... 5B1%5D.gif

Τέλος το θέμα μου το έκανα έτσι


Αν το θέλετε έτσι πως είναι Θα πρέπει να αντιγαψετε τον φάκελο στην διεύθυνση που είπα στην αρχή ( /usr/share/screenlets/Radio/themes )

Αλλά πως μπορώ να το ανεβάσω στο forum ;
