Abstract

The invention discloses a multi-touch method and system based on the winning Kylin operating system. Firstly, a multi-touch driving module is programmed into the kernel of the winning Kylin operating system to receive the original data of the touch screen, and according to Generate event queue files from raw data; then integrate event queue file parsing module and multi-point event parsing and transfer module in the inner code of Qt application platform graphical user interface module to complete parsing of event queue file data at the user layer of the operating system , and complete the multi-point event judgment and upward transfer function at the user layer of the operating system; so that application developers do not need to care about changes in the underlying development platform and driver layer, and only need to use Qt's multi-touch related user graphical interface for direct Development, the multi-touch function is realized under the Kylin operating system, which reduces the difficulty of multi-touch application development and improves the portability of multi-touch applications.

Description

technical field [0001] The invention relates to a multi-touch screen application development technology, in particular to a multi-touch method based on the winning Kylin operating system. Background technique [0002] Multi-touch is a new means of human-computer interaction, allowing computer users to control the computer through multiple fingers or touch points at the same time, providing users with a natural and convenient way to directly interact with information content. A variety of multi-touch input devices (capacitive touch screens, resistive touch screens, infrared touch screens, optical touch screens, etc.) have appeared on the market; there are also some new versions of operating systems such as Apple's iOS system, Microsoft's Windows 8, Google's Android The operating system supports the multi-touch function and provides multi-touch APIs to application developers. [0003] However, under the winning Kirin operating system, the multi-touch function cannot be realiz...
