c++ - windows 7触摸屏驱动，多显示器

Question

我正在为 Windows 7 开发触摸屏驱动程序，当连接单个显示器时它工作正常，但当我连接第二个显示器时，触摸输入仅映射到主显示器。有什么方法可以将触摸输入映射到辅助显示器？

任何输入或指示将不胜感激？

Answer 1

据我所知，这在 Windows 7 中是不可能的，但根据 MSDN 的说法，在 Windows 8 中应该是可能的:

HID Descriptor for Digitizers

Starting with Windows 8, a touch digitizer must appear as a touch screen (page = 0x0D, usage = 0x04). A stylus digitizer must appear as an integrated pen (page = 0x0D, usage = 0x02) or an external pen (page = 0x0D, usage = 0x01). Integrated touch and pen devices are mapped to the display that they are physically connected to. External pen devices are mapped to the virtual desktop.
