get_axis_value

Description:

[ Version ( since = "1.6" ) ]
public bool get_axis_value (double[] axes, InputAxis axis, out double value)

Extracts the value of the given axis of a InputDevice from an array of axis values.

An example of typical usage for this function is:

  ClutterInputDevice *device = clutter_event_get_device (event);
  gdouble *axes = clutter_event_get_axes (event, NULL);
  gdouble pressure_value = 0;

  clutter_input_device_get_axis_value (device, axes,
                                       CLUTTER_INPUT_AXIS_PRESSURE,
                                       &pressure_value);

Parameters:

this	a InputDevice
axes	an array of axes values, typically coming from get_axes
axis	the axis to extract
value	return location for the axis value

Returns:

true if the value was set, and false otherwise
