Untung-nya, awal tahun ini ada beberapa developer yang peduli dengan kelangsungan proyek ini dan akhir-nya membuat sebuah komunitas untuk melanjutkan pengembangan proyek QtJambi, sekarang teman-teman bisa melihat perkembangan proyek QtJambi ini pada halaman QtJambi Community 
. Hm.. penasaran dengan tampilan aplikasi yang dibangun menggunakan QtJambi ? Kalau iya, silahkan lihat screenshot dibawah ini :
Hmm… keren bukan ?
Tetapi sama seperti SWT (Standart Widget Toolkit) yang sudah dibahas diatas, aplikasi yang dibangun menggunakan QtJambi ini benar-benar mengakses native library yang terdapat pada Sistem Operasi. Meskipun masalah tersebut (baca library) sudah disediakan oleh QtJambi, tapi jika kita ingin men-distribusikan aplikasi ke client. Kita masih harus memasukkan native library tersebut ke dalam CLASSPATH aplikasi, agar aplikasi yang kita bangun bisa berjalan dengan sempurna. Tapi kalau masalah ini bisa teman-teman akomodasi, kenapa tidak dicoba kan ? Dan untuk teman-teman yang memang ingin mencoba membangun aplikasi menggunakan QtJambi, jangan lupa untuk menambahkan kebutuhan-kebutuhan dibawah ini kedalam CLASSPATH aplikasi yang teman-teman buat. Kebutuhan-kebutuhan tersebut yaitu :- qtjambi-x.x.x.jar, dimana x adalah nomor versi library qtjambi
- qtjambi-os-x.x.x.jar, dimana os adalah sistem operasi target dan x adalah nomor versi dari library qtjambi
