AWT (Abstract Window Toolkit) – SUN Microsystem -> Oracle Product
AWT (Abstract Window Toolkit) ini adalah GUI Toolkit pertama pada bahasa pemrograman Java, sayang-nya AWT ini sangat-sangat kekurangan komponen yang biasa digunakan untuk membangun sebuah aplikasi desktop secara lengkap (komponen tabel saja tidak ada ) Terlepas dari kurang-nya komponen GUI yang terdapat pada AWT (Abstract Window Toolkit), aplikasi yang dibangun menggunakan AWT (Abstract Window Toolkit) akan tampak seperti aplikasi native. Maksudnya yaitu, jika aplikasi yang dibangun menggunakan AWT (Abstract Window Toolkit) ini dijalankan pada Sistem Operasi Windows. Maka aplikasi ini akan terlihat seperti aplikasi Windows pada umum-nya, dan begitu juga jika dijalankan pada Sistem Operasi Mac ataupun GNU/Linux. Kenapa ini bisa terjadi, karena AWT (Abstract Window Toolkit) ini benar-benar memanggil native subrutin untuk menggambar setiap komponen-nya ke layar. Tidak percaya ? Mari kita lihat tampilan ke 2 screenshot dibawah ini:
