Abstract

The invention provides a VxWorks and Qt event communication method and device. The method comprises the steps of monitoring whether or not event information to be processed exists in a WindML libraryof a VxWorks operating system; if the event information to be processed exists in the WindML library of the VxWorks operating system, controlling a callback function to filter the event information tobe processed, and obtaining first event information, wherein the first event information is event information of input equipment; writing labeled information corresponding to the first event information into a pipeline; according to the operation of writing the labeled information corresponding to the first event information into the pipeline, calling a slot function so that the slot function canread the first event information, convert the first event information into second event information capable of being recognized by Qt and store the second event information into an information queueof the Qt and the Qt can process the second event information. VxWorks and Qt event communication is achieved, an application program based on the Qt can run on the VxWorks operating system, and the advantages of good reliability and excellent real-time performance of the VxWorks operating system are sufficiently utilized.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a method and device for event communication between VxWorks and Qt. Background technique [0002] The VxWorks operating system is an embedded real-time operating system designed and developed by the American windRiver company in 1983. It is widely used in high-tech technologies such as communications, military, aviation, and aerospace for its good reliability and excellent real-time performance. and fields with extremely high real-time requirements. [0003] Qt is a multi-platform C++ GUI application framework. It provides application developers with all the functionality needed to create state-of-the-art graphical user interfaces. Qt is a completely object-oriented programming, so it has the advantages of easy expansion and component programming. Due to the advantages of Qt, many application software are developed based on Qt. [0004] The current...
