PyGTK, and will in the future be moved to some other package. If your
application needs this widget, feel free to use it, as the widget does work
and is useful in some applications; it's just not of general interest.
However, it will eventually move out of the PyGTK distribution.</p></div><p>The <a class="link" href="class-gtkgammacurve.html" title="gtk.GammaCurve"><code class="classname">gtk.GammaCurve</code></a>
widget is a variant of <a class="link" href="class-gtkcurve.html" title="gtk.Curve"><code class="classname">gtk.Curve</code></a>
specifically for editing gamma curves, which are used in graphics
applications such as the <span class="application">Gimp</span>. The <a class="link" href="class-gtkgammacurve.html" title="gtk.GammaCurve"><code class="classname">gtk.GammaCurve</code></a>
widget shows a curve which the user can edit with the mouse just like a
<a class="link" href="class-gtkcurve.html" title="gtk.Curve"><code class="classname">gtk.Curve</code></a>
widget. On the right of the curve it also displays 5 buttons, 3 of which
change between the 3 curve modes (spline, linear and free), and the other 2
set the curve to a particular gamma value, or reset it to a straight
line.</p></div><div class="refsect1" title="Constructor"><a name="constructor-gtkgammacurve"></a><h2>Constructor</h2><pre class="programlisting"><code class="constructorsynopsis"> <span class="methodname">gtk.GammaCurve</span>(<span class="methodparam"></span>)</code></pre><table border="0" width="100%" bgcolor="#FFECCE"><col align="left" valign="top" width="0*"><tbody><tr><td><p><span class="term"><span class="emphasis"><em>Returns</em></span> :</span></p></td><td>a new gammacurve widget</td></tr></tbody></table><p>Creates a new <a class="link" href="class-gtkgammacurve.html" title="gtk.GammaCurve"><code class="classname">gtk.GammaCurve</code></a>
