Tkinter menyediakan bar skrol untuk widget seperti Senarai , Kotak Teks, Kanvas dan Entri. Walau bagaimanapun, memaparkan grid widget label dengan bar skrol boleh mencabar kerana widget ini tidak menyokong bar skrol secara asli.
1. Widget Teks dengan window_create:
2. Kanvas dengan Bingkai Terbenam:
3. Lukisan Terus pada Kanvas:
