Bonjour,

J'ai créé une classe dérivée de JTextPane pour faire de la coloration syntaxique et repérer certains éléments intéressants du texte. Maintenant, je voudrais pouvoir ajouter un menu contextuel sur ces éléments du texte.

J'ai cherché et j'ai bien vu des choses comme HyperLinkListener, mais çà ne fait pas vraiment ce que je veux et c'est pour du HTML.
Quelqu'un aurait-il des idées sur la façon de procéder ?

Pour tester mon code actuel: http://test04145.mutu.sivit.org/Wiki...iaCleaner.jnlp

Code MediaWikiPane.java : Sélectionner tout - Visualiser dans une fenêtre à part
