C++ (Cpp) NotifyDeviceChange Examples

Example #1

File: PresentationDeviceManager.cpp Project: npark-mozilla/gecko-dev

NS_IMETHODIMP
PresentationDeviceManager::UpdateDevice(nsIPresentationDevice* aDevice)
{
  NS_ENSURE_ARG(aDevice);
  MOZ_ASSERT(NS_IsMainThread());

  if (NS_WARN_IF(!mDevices.Contains(aDevice))) {
    return NS_ERROR_FAILURE;
  }

  NotifyDeviceChange(aDevice, MOZ_UTF16("update"));

  return NS_OK;
}

Example #2

File: PresentationDeviceManager.cpp Project: heiher/gecko-dev

// nsIPresentationDeviceListener
NS_IMETHODIMP
PresentationDeviceManager::AddDevice(nsIPresentationDevice* aDevice)
{
  NS_ENSURE_ARG(aDevice);
  MOZ_ASSERT(NS_IsMainThread());

  if (NS_WARN_IF(mDevices.Contains(aDevice))) {
    return NS_ERROR_FAILURE;
  }

  mDevices.AppendElement(aDevice);

  NotifyDeviceChange(aDevice, u"add");

  return NS_OK;
}

Example #3

File: PresentationDeviceManager.cpp Project: heiher/gecko-dev

NS_IMETHODIMP
PresentationDeviceManager::RemoveDevice(nsIPresentationDevice* aDevice)
{
  NS_ENSURE_ARG(aDevice);
  MOZ_ASSERT(NS_IsMainThread());

  int32_t index = mDevices.IndexOf(aDevice);
  if (NS_WARN_IF(index < 0)) {
    return NS_ERROR_FAILURE;
  }

  mDevices.RemoveElementAt(index);

  NotifyDeviceChange(aDevice, u"remove");

  return NS_OK;
}
