Editeur texte sous netbeans
Salut tous,
Je cherche à personnaliser la couleur, la taille, la police et la forme de mon texte écrit sur un JTextPane
Ce que je désire développer rassemble trop à l'éditeur du word, yahooMail, etc. ..
Voilà le code que j'ai et qui regroupe toutes les fonctionnalités souhaitées.
Code:

Le problème c'est comment faire pour appeler cet éditeur?
Et puis, comment valider le choix sur le texte déjà écrit?
Merci pour votre attention..
