## Detailed Description

A channel from an element implementing the Gst::Tuner interface.

The Gst::TunerChannel object is provided by an element implementing the Gst::Tuner interface.

Gst::TunerChannel provides a name and flags to determine the type and capabilities of the channel. If the Gst::TUNER_CHANNEL_FREQUENCY flag is set, then the channel also information about the minimum and maximum frequency, and range of the reported signal strength.

## Friends And Related Function Documentation

Glib::RefPtr< Gst::TunerChannel > wrap | ( | GstTunerChannel * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
