مشكلة فى Gui

هنا توجد بانل اسمها mainComponentPanel عليها

componentPanel & typePanel

المشكلة انى عاوز البانل typePanel

تكون تحت البانل componentPanel

هى تظهر صغيرة جدا جدا

أريدها تظهر بطول مناسب و عرض مناسب

و الهدف منها عندما اضغط على زرار الخط تظهر هذه البانل بها 3 انواع من الخطوط رفيع - سميك - سميك جدا

كما فى برنامج الرسام بتاع الوندوز

و جربت استعمل ال Box

لكن ما نفع الأمر

الكود هذا الإنترفيس فقط
