Ajout dynamique de boutons à un panneau par appui sur un autre panneau

Question

J'ai un cadre sur lequel j'ai créé un panneau principal.

Sur ce panneau sont présents 2 panneaux de plus. Ce que je veux, c'est que j'ai des boutons sur panneau1, et maintenant, une fois que je clique sur le bouton, je veux dessiner un objet 2d sur le 2ème panneau.

J'ai essayé beaucoup de choses mais c'était en vain. S'il vous plaît aidez-moi dans ce cas. Toute aide serait appréciée. Merci,

Jetez un oeil à Swing Action

Vous pouvez ajouter des actions aux boutons et passer les panneaux comme paramètres
