 Java ile menü yapiminda temel üç unsura ihtiyacimiz olacak: MenuBar, Menu, MenuItem<\/b><\/p>\n


\n<\/font>\"\"<\/p>\n

MenuBar<\/span><\/b> (menü çubugu), sekilde de gorüldügü gibi, menümüzün temelidir. <\/o:p><\/span><\/p>\n

Onun üzerine Menu<\/b> gelir. Menu tek basina pasiftir. Ona tiklayinca açilan ögelere ise MenuItem<\/b> denir.<\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

Simdi ilk yapacagimiz sey bir Frame olusturmak:
\n<\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

\n

JFrame frame = <\/span>new<\/span><\/b> JFrame(<\/span>"Menü kullanimi"<\/span>);<\/span><\/o:p><\/span><\/p>\n

            <\/span>frame.setVisible(<\/span>true<\/span><\/b>);<\/span><\/o:p><\/span><\/p>\n

            <\/span>frame.setSize(400,200);<\/span><\/o:p><\/span><\/p>\n

            <\/span>frame.setDefaultCloseOperation(JFrame.<\/span>EXIT_ON_CLOSE<\/span><\/i>);<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

Bunun üzerinde fazla durmuyorum. Diger makalelerimizde daha ayrintili sekillerde anlatmaya çalismistik.<\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

Sira geldi bir MenuBar olusturmaya ve frame nesnesine eklemeye:<\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

\n

JMenuBar menubar = <\/span>new<\/span><\/b> JMenuBar();<\/span><\/o:p><\/span><\/p>\n

frame.setJMenuBar(menubar);<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

Temeli hazirladik. <\/o:p><\/span><\/p>\n

Bu MenuBar’in üzerine iki adet Menu yerlestirelim. Bunlar ‘Dosya’ ve ‘Yardim’ olsun. <\/o:p><\/span><\/p>\n

\n

JMenuBar menubar = <\/span>new<\/span><\/b> JMenuBar();<\/span><\/o:p><\/span><\/p>\n

frame.setJMenuBar(menubar);<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

\n

JMenu yardim = <\/span>new<\/span><\/b> JMenu(<\/span>"Yardim"<\/span>);<\/span><\/o:p><\/span><\/p>\n

menubar.add(yardim);<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

Menu’leri MenuItem’lerin tasnif edildigi basliklar olarak tasarlamaliyiz.<\/o:p><\/span><\/p>\n

‘Dosya’ kismina “yeni, kaydet, farkli kaydet, çikis” gibi elemanlar; ‘yardim’ kismina ise “iletisim, hakkimizda” gibi elemanlar yerlestirebiliriz mesela. <\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

Simdi MenuItem’leri yerlestirelim. Mantik yine ayni:<\/o:p><\/span><\/p>\n

\n

JMenuItem yeni = <\/span>new<\/span><\/b> JMenuItem(<\/span>"Yeni"<\/span>);<\/span><\/o:p><\/span><\/p>\n

dosya.add(yeni);<\/o:p><\/span><\/p>\n

…<\/o:p><\/span><\/p>\n

…<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

Bu MenuItem’ler bir nevi butondur. Tiklayinca bir görefi yerine getirirler.<\/o:p><\/span><\/p>\n

O zaman biz de aynen bir butona uygular gibi ActionListener sinifinin actionPerformed metodunu ‘cikis’ adli MenuItem’e uygulayalim. ‘cikis’ MenuItem’ine basinca uygulamamis sonlandirilsin:<\/o:p><\/span><\/p>\n

 <\/o:p><\/span><\/p>\n

\n

cikis.addActionListener(<\/span>new<\/span><\/b> ActionListener() {<\/span><\/o:p><\/span><\/p>\n

                  <\/span><\/span><\/o:p><\/span><\/p>\n

                  <\/span><\/span>@Override<\/span><\/o:p><\/span><\/p>\n

                  <\/span><\/span>public<\/span><\/b> <\/span>void<\/span><\/b> actionPerformed(ActionEvent e) {<\/span><\/o:p><\/span><\/p>\n

                        <\/span>System.exit<\/i>(0);<\/span><\/o:p><\/span><\/p>\n

                        <\/span><\/span><\/o:p><\/span><\/p>\n

                  <\/span>}<\/span><\/o:p><\/span><\/p>\n

            <\/span>});<\/span><\/o:p><\/span><\/p>\n<\/div>\n

 <\/o:p><\/span><\/p>\n

Iste bu kadar!<\/o:p><\/span><\/p>\n
