gdk_device_tool_get_hardware_id (
  GdkDeviceTool* tool

Description [src]

Gets the hardware ID of this tool, or 0 if it’s not known. When non-zero, the identificator is unique for the given tool model, meaning that two identical tools will share the same hardware_id, but will have different serial numbers (see gdk_device_tool_get_serial()).

This is a more concrete (and device specific) method to identify a GdkDeviceTool than gdk_device_tool_get_tool_type(), as a tablet may support multiple devices with the same GdkDeviceToolType, but having different hardware identificators.

Available since: 3.22

Return value

Type: guint64

The hardware identificator of this tool.
