The invention provides a split-screen display method based on a hook technology. The split-screen display method comprises the steps that an application opening operation instruction of a client operation area is monitored, and initial application data are acquired through a global hook A of a first dynamic link library; drawing an application window for each application according to the initial application data; monitoring an application change operation instruction of the client operation area and acquiring application change data through a global hook B of the second dynamic link library; and performing application window adjustment on the changed application according to the application change data. Meanwhile, the invention further provides a split-screen display device and system based on the hook technology and a storage medium. According to the technical scheme provided by the invention, window position and window size adjustment and superposition layering operation can be flexibly realized for a plurality of applications, top or bottom operation can be carried out on the target application window, the use is convenient, the problem of limitation of split-screen display is solved, and the operation experience of a client is effectively improved.
Description
technical field [0001] The present invention relates to the technical field of split-screen display, and in particular, to a method, device, system and storage medium for split-screen display based on hook technology. Background technique [0002] In applications such as exhibition display and operation center display, high-performance computers and multi-screen graphics cards are often used to build an ultra-high-resolution desktop, output to the splicing screen for display, and then use split-screen software to realize pictures, videos, and documents. , web pages and split-screen display output of various related software. The split-screen software usually uses a stand-alone version of the Supervisory Control And Data Acquisition (SCADA) system. After running, the user can divide the desktop according to the needs through the operation interface, and divide the layout of different application windows. The application window implements a split-screen display of an applicat...
