+ | |||
+ | This unit provides the Mouse device interface and mouse API to be used by both drivers and applications. | ||
+ | |||
+ | The API includes functions to create, register, locate, read, write, control and configure each connected mouse device. | ||
+ | |||
+ | The API supports a global mouse buffer so multiple devices can feed data into a common buffer as well as a buffer per device to allow each device to be used for a specific purpose. For example an application with two separate displays may choose to have a mouse or pointing device to control each one individually. | ||

Description
Ultibo Mouse Interface unit
Mouse Devices
This unit provides the Mouse device interface and mouse API to be used by both drivers and applications.
The API includes functions to create, register, locate, read, write, control and configure each connected mouse device.
The API supports a global mouse buffer so multiple devices can feed data into a common buffer as well as a buffer per device to allow each device to be used for a specific purpose. For example an application with two separate displays may choose to have a mouse or pointing device to control each one individually.
