Pengguna dapat membuat aplikasi dengan antarmuka grafis dengan kode Octave. Hal ini dapat dilakukan dengan menggunakan beberapa fungsi bawaan GNU Octave.[31] Di bawah ini beberapa contohnya:
# membuat figure dan panel di dalamnya
f = figure;
# create a button (default style)
button1 = uicontrol (f, "string", "A Button", "position",[10 10 150 40]);
# membuat kontrol edit
e1 = uicontrol (f, "style", "edit", "string", "editable text", "position",[10 60 300 40]);
# membuat kotak cek
c1 = uicontrol (f, "style", "checkbox", "string", "a checkbox", "position",[10 120 150 40]);
# slider
s1 = uicontrol (f, "style", "slider", "position", [10 230, 300, 20]);
# teks
t1 = uicontrol (f, "style", "text", "string", "label / text", "position", [10 260, 300, 20]);
# tombol sakelar
tb1 = uicontrol (f, "style", "togglebutton", "string", "a togglebutton", "position", [10 290, 300, 20]);
# membuat grup tombol
gp = uibuttongroup (f, "Position", [ 0 0.75 1 1]);
# membuat tombol dalam grup
b1 = uicontrol (gp, "style", "radiobutton", "string", "Choice 1", "Position", [ 10 50 100 50 ]);
b2 = uicontrol (gp, "style", "radiobutton", "string", "Choice 2", "Position", [ 10 10 100 50 ]);
# membuat tombol di luar grup
b3 = uicontrol (f, "style", "radiobutton","string", "Not in the group","Position", [ 10 170 200 50 ]);
prompt = {"Width", "Height", "Depth"};
defaults = {"1.10", "2.20", "3.30"};
rowscols = [1,10; 2,20; 3,30];
dims = inputdlg (prompt, "Enter Box Dimensions", rowscols, defaults);
my_options = {"An item", "another", "yet another"};
[sel, ok] = listdlg ("ListString", my_options, "SelectionMode", "Multiple");
if (ok == 1)
msgbox ("You selected:");
for i = 1:numel (sel)
msgbox (sprintf ("\t%s", my_options{sel(i)}));
endfor
else
msgbox ("You cancelled.");
endif
