30 /** @class AudioMappingView
31 * @brief This class displays the mapping of one set of audio channels to another,
32 * with gain values on each node of the map.
34 * The AudioMapping passed to set() describes the actual channel mapping,
35 * and the names passed to set_input_channels() and set_output_channels() are
36 * used to label the rows and columns.
38 * The display's row count is equal to the AudioMapping's input channel count,
39 * and the column count is equal to the number of name passed to
40 * set_output_channels(). Any other output channels in the AudioMapping are
41 * hidden from view. Thus input channels are never hidden but output channels
