<h2 class="chapter">35 GUI Development</h2>
<p>Octave is principally a batch or command-line language. However, it does
offer some limited features for constructing graphical interfaces for
interacting with users.
</p>
<p>The GUI elements available are I/O dialogs and a progress bar. For example,
rather than hardcoding a filename for output results a script can open a dialog
box and allow the user to choose a file. Similarly, if a calculation is
expected to take a long time a script can display a progress bar.
</p>
<p>Several utility functions make it possible to store private data for use with
a GUI which will not pollute the user’s variable space.
</p>
<p>Finally, a program written in Octave might want to have long term storage of
preferences or state variables. This can be done with user-defined
preferences.
