inputdevices

dtkinputdevices module

Introduction

dtkinputdevices provides access to input devices and global input settings on deepin and uos.

Structure

There are 9 classes in this module:

• DInputDeviceManager InputDevices manager, can be directly constructed
• DInputDeviceSetting global settings, can be acquired from manager
• DInputDevice abstract device base class (also generic device class), can be instantiated by manager
• DInputDevicePointer abstract pointer device, as a abstract layer, it cannot be instantiated
• DInputDeviceMouse mouse device, derived from DInputDevicePointer, can be instantiated by manager
• DInputDeviceTouchPad touch pad device, derived from DInputDevicePointer, can be instantiated by manager
• DInputDeviceTrackPoint track point device, derived from DInputDevicePointer, can be instantiated by manager
• DInputDeviceTablet tablet pad and tablet tools device, derived from DInputDevicePointer, can be instantiated by manager
• DInputDeviceKeyboard keyboard device, derived from DInputDevice, can be instantiated by manager
