MTK矩陣菜單用法

有次一個客戶須要設計一個六宮的矩陣菜單,簡單看了一下菜單API,發現也十分簡單,使用矩陣菜單使用前要先調用 wgui_fixed_matrix_create_menu初始化,而後調用wgui_fixed_matrix_begin_add_one_item給菜單添加菜單項,使用FOR調用wgui_fixed_matrix_add_one_item添加,再使用configure_fixed_matrix設置每項菜單個數大小.最後使用wgui_fixed_matrix_end_add_one_item結束矩陣菜單設置.剩下就是根據須要對菜單屬性設置了.MMI_fixed_icontext_menuitem.flags和MMI_fixed_matrix_menu.flags
