Implementation of C++ class object reflection mechanism (dynamically creating class objects and assigning values to class fields)
1. Dynamic creation of classes The class to be created must inherit the same parent class before using the parent class pointer to create the corresponding subclass. class QObject {<!– –> public: QObject(){<!– –>} ~QObject(){<!– –>} } 1.2. Register the class name, class character name, and class field data type into the corresponding linked list. […]

SFML2.6 graphics module–designing entities with vertex arrays
Introduction SFML provides simple classes to represent the most common 2D entities. While more complex entities can be easily created from these basic components, this is not always the most efficient solution. For example, if you draw a large number of sprites, you will quickly reach the limits of your graphics card. The reason is […]
Research on a method of assigning memory to structures based on C++
This article discusses a method of assigning memory to structures based on C++. Through this method, while assigning memory, it is more friendly to code reading, can be applied to some actual working environments, and can improve development efficiency and reduce maintenance costs. . Ask a question In a certain iteration of a certain project, […]
XMind2TestCase tool for efficiently designing test cases
1. Background: In the software testing process, the most important and core thing is the design of test cases. It is also one of the tasks that the testing team and the testing team spend the most time on daily. However, the traditional test case design process has many pain points: 1. Using Excel tables […]
