ciao a tutti,
sto realizzando un editor di testo con interfaccia grafica,
utilizzando gtk, glade e python come linguaggio di programmazione, ma non
riesco a fare in modo di stampare quello che l'utente ha scritto nell'area di
testo (textview), vi posto il sorgente nell'allegato sperando che possiate
aiutarmi !
Grazie
PS : se volete provare l'applicazione per segnalarmi altri
problemi oltre a questo, ricordatevi di rinominare l'allegato glade in prova.
glade
ciao
