EVT_PAINT non lancé

Salut à vous !

J'essaie de faire un bouton à états (enabled, disabled, mouse over, clicked) qui aurait une image par état.
Sous windows je n'ai aucun problème, mais sous Linux (Debian) l'évènement EVT_PAINT ne se lance jamais, même avec un Refresh...

Je vous mets le code de mon bouton, eclairez moi si vous avez des suggestions, car là je piétine...

Salut,
Il me semble qu'il faut faire un Update après le Refresh :
Doc wxWidget :

Citation:

---

Causes this window, and all of its children recursively (except under wxGTK1 where this is not implemented), to be repainted. Note that repainting doesn't happen immediately but only during the next event loop iteration, if you need to update the window immediately you should use Update instead.

---

Euh, normalement ce n'est pas nécessaire, mais j'ai quand même essayé, sans résultat...
Merci quand même ;)

Salut,
Effectivement, j'ai précédemment répondu trop vite.
En fait, la doc dit explicitement qu'on ne peut surcharger le PaintEvent pour redessiner un contrôle existant :

Citation:

---

Envoyé par wxPaintEvent

Please notice that in general it is impossible to change the drawing of a standard control (such as wxButton) and so you shouldn't attempt to handle paint events for them as even if it might work on some platforms, this is inherently not portable and won't work everywhere.

Il faut que tu dérives de wxControl pour gérer complètement l'affichage. Bref refaire ton bouton 100% maison

OK, merci du renseignement !
