NOTE this widget is considered too specialized/little-used for
|
|
GTK+, 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, we are not accepting new features for
|
|
the widget, and it will eventually move out of the GTK+
|
|
distribution.

The #GtkGammaCurve widget is a subclass of #GtkCurve specifically for
|
|
editing gamma curves, which are used in graphics applications such as the
|
|
Gimp.

The #GammaCurve widget shows a curve which the user can edit with the mouse
|
|
just like a #GtkCurve 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.
