Device.getVendorId

Returns the vendor ID of this device, or null if this information couldn't be obtained. This ID is retrieved from the device, and is thus constant for it.

This function, together with [gdk.device.Device.getProductId], can be used to eg. compose #GSettings paths to store settings for this device.

static GSettings *
get_device_settings (GdkDevice *device)
{
  const gchar *vendor, *product;
  GSettings *settings;
  GdkDevice *device;
  gchar *path;

  vendor = gdk_device_get_vendor_id (device);
  product = gdk_device_get_product_id (device);

  path = g_strdup_printf ("/org/example/app/devices/%s:%s/", vendor, product);
  settings = g_settings_new_with_path (DEVICE_SCHEMA, path);
  g_free (path);

  return settings;
}
