Select Shape [java]

[razvandragos29]

Salut am de facut un mini paint la facultate .

Creati un editor grafic simplu, cu 3 butoane: de adaugare in fereastra a unui cerc, de adaugare a unui patrat si de stergere a unei forme (cerc sau patrat) -forma ce se poate selecta cu mouse-ul.

Salut am mai lucrat la chestia asta insa tot am anumite probleme:

nu pot sa fac icna stergerea si atunci cand vreu sa verific daca locul unde am dat click face parte dintr-un dreptunghi merge doar pentru ultimu dreptunghi desenat pentru cele desenate anterior nu merge .. Am rescris si o parte din cod si acum cred ca este mai clean ..
