get_hardware_id

Description:

public uint64 get_hardware_id ()

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 [[email protected]_serial]).

This is a more concrete (and device specific) method to identify a `GdkDeviceTool` than [[email protected]_tool_type], as a tablet may support multiple devices with the same `GdkDeviceToolType`, but different hardware identificators.

Parameters:

this	a `GdkDeviceTool`

Returns:

The hardware identificator of this tool.
