Embodiment Construction

[0027] Please refer to figure 1 As shown, a method for generating a measurement tool through a mouse track includes the following steps:

[0028] Step 10, create a project project, and create a canvas window in the project project;

[0029] Step 20, in the present embodiment utilize delphi development tool (it can also use other development tools) packaged message processing function (generally obtain the message processing function of mouse and comprise: WM_LBUTTONDOWN, WM_MOUSEMOVE, WM_LBUTTONUP.), obtain mouse in described The operation information on the canvas window (that is, the press, drag, and pop-up messages of the processing mouse); the operation information includes: the position when the mouse is pressed, the position that the mouse passes through at each moment when the mouse is pressed and dragged;

[0030] Step 30, using the obtained mouse operation information to calculate the relevant information of the graphics of the measuring tools to be displayed, the me...

Abstract

The invention discloses a method for generating a measuring tool by a mouse track, which comprises the following steps of: first, building a project engineering and building a canvas window in the project engineering; second, obtaining the operation information of the mouse in the canvas window by an information process function packaged by the canvas window, wherein the operation information includes a position of the mouse when the mouse is pressed down and the positions where the mouse passes at all moments when the mouse is pressed down and dragged; third, calculating the relevant information of images of the measuring tools to be displayed by the obtained operation information of the mouse, wherein the measuring tools include a ruler, a protractor, a thirty-degree right-angle triangular board and a forty-five-degree right-angle triangular board; and at last, displaying the images of the measuring tools to be displayed on the canvas by a drawing function interface provided by a 2D(Two-dimensional) drawing library of the operating system according to the relevant information of the images of the measuring tools. The method for generating the measuring tool by the mouse track generates a measuring tool in an electronic white board via the mouse track so as to use the measuring tool to measure a target.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic whiteboards, in particular to a method for generating measuring tools through mouse tracks. 【Background technique】 [0002] In recent years, electronic whiteboard technology has developed rapidly in teaching, so that teachers do not need to achieve teaching purposes under the conditions of traditional chalk blackboards. In the course of the teacher's lectures, it often involves teaching the measurement methods of length units and other related units. This requires the design of an intelligent method that can simulate physical measurement tools (such as rulers, protractors, 30-degree right triangles, 45-degree Right-angled triangle), use measurement tools to measure the target, so as to achieve this teaching purpose on the electronic whiteboard. The current electronic whiteboard is still unable to simulate physical measurement tools, and physical measurement tools are still used to measure ta...
