Embodiment Construction
[0011] Please refer to figure 1 As shown, a method for realizing multi-person split-screen operation of the present invention includes the following steps:
[0012] Step 10, use the Visual Studio development tool to create a C# application project based on the .Net Framework4 framework, create a new application window, and divide the window into several areas;
[0013] Step 20, encapsulating the canvas component used by the application project, and writing each response processing function of the touch event in the canvas component, generating each corresponding canvas according to each divided window area; this step 20 specifically includes the following steps:
[0014] Step 200, the canvas component directly inherits from the Canvas class of the application project, and rewrites the redrawing function of the canvas component: OnRender(DrawingContext dc);
[0015] For example, to draw a straight line from A (10, 10) to B (120, 100) on the canvas, the color is blue, and the p...

The invention provides a method for realizing multiplayer split-screen operation. The method comprises the following steps of: creating a C# application project based on a framework .Net Framework4, creating an application program window, and dividing the window into a plurality of regions; encapsulating a canvas component used by the application project, compiling response processing functions for touch events, and generating all corresponding canvases according to all divided window regions; parsing message data of the touch events, and converting the message data into corresponding service logic processing; and displaying a final effect on the canvases by combining a graphics drawing and transforming function encapsulated in the application project. The method for realizing the multiplayer split-screen operation has the advantages that multiple canvases can exist in the same application project, and the mutual operating and writing can be simultaneously carried out on regions, corresponding to the canvases, of an electronic whiteboard in a multipoint manner.
Description
technical field [0001] The invention relates to the technical field of electronic whiteboards, in particular to a method for realizing multi-person split-screen operation. Background technique [0002] In recent years, electronic whiteboard technology has developed rapidly in teaching, making education without traditional chalk and blackboard a reality, and making the education process electronic. At present, most of the products in the market are single-pen and single-screen writing, that is, one pen and one canvas mode. In terms of teaching, this mode has many inconveniences and cannot support multiple people to write at the same time. However, in teaching, multiple students are often required to perform writing operations on the electronic whiteboard, so the single-stroke, single-screen electronic whiteboards currently on the market cannot meet the needs of users. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
