Création d'une grille modifiable (à peindre) dans JavaFX
Actuellement, il existe 2 ensembles de grilles. le premier gridset est une grille 5x4 qui a des images de la carte. En plus de cela, il y a une grille qui a toutes les petites tuiles à chacune des boîtes de grille 5x4.
J'ai donc besoin d'avoir de grandes images dans un motif de grille 5x4, avec des mini tuiles 16x16 dans chacune de ces tuiles, et chaque mini tuile doit être peignable (ou avoir des images) au-dessus de l'image sous-jacente qui existe dans les grands acres.

Comme vous pouvez le voir, le FXML est très désordonné et semble inutile dans l'ensemble.
Ma question est donc: Comment puis-je dessiner tout cela, en utilisant aussi peu de grilles ou aucune si possible, tout en me permettant d'accéder aux tuiles de la grille (colonne,ligne,données,etc.) via un composant bean pratique?
