GwyShader is a spherical angle selector that allows user to change angle by simply moving the north pole of a sphere around with mouse. It can display the sphere colored with various GwyGradient's.
GtkWidget *
gwy_shader_new (const gchar *gradient);
Creates a new spherical shader.
The widget takes up all the space allocated for it.
| gradient | Name of gradient to color the spehere with.  Can be  | 
gdouble
gwy_shader_get_theta (GwyShader *shader);
Returns the theta coordinate of a shader.
gdouble
gwy_shader_get_phi (GwyShader *shader);
Returns the phi coordinate of a shader.
void gwy_shader_set_theta (GwyShader *shader,gdouble theta);
Sets the theta coordinate of a shader.
| shader | A shader. | |
| theta | The theta coordinate to set.  See  | 
void gwy_shader_set_phi (GwyShader *shader,gdouble phi);
Sets the phi coordinate of a shader.
| shader | A shader. | |
| phi | The phi coordinate to set.  See  | 
void gwy_shader_set_angle (GwyShader *shader,gdouble theta,gdouble phi);
Sets the spherical angle of a shader.
| shader | A shader. | |
| theta | The theta coordinate to set.  See  | |
| phi | The phi coordinate to set.  See  | 
const gchar *
gwy_shader_get_gradient (GwyShader *shader);
Returns the name of color gradient a shader uses.
 The gradient name.  It must not be modified or freed.  It may
differ the name that was used on initialization or set with
gwy_shader_set_gradient(), if the gradient didn't exist or
was renamed meanwhile.
void gwy_shader_set_gradient (GwyShader *shader,const gchar *gradient);
Sets the gradient a shader uses.
GtkUpdateType
gwy_shader_get_update_policy (GwyShader *shader);
Returns the update policy of a shader.
void gwy_shader_set_update_policy (GwyShader *shader,GtkUpdateType update_policy);
Sets the update policy of a shader.

“angle-changed” signalvoid user_function (GwyShader *gwyshader, gpointer user_data)
The ::angle-changed signal is emitted when the spherical angle changes.
