Starting from a memory leak?Very simple entry procedure, you should be familiar with it ^_^#include In the context of the delete from Qt, we mentioned that the program has a memory leak (the representation is that the destructor is not called), and there are three workarounds:
Assigning a Label object to a stack instead of a heap
Set tag bit qt::wa_deleteonclose for label
Call Delete yourself to delete the Label object that is assigned to the heap by new

Clause 3: select a smart pointer based on functions and implementation principlesThere are many types of smart pointers. The implementation principles can be divided into two categories: ownership-based transfer and reference-based counting. The built-in std: auto_ptr in C ++ is a smart pointer based on ownership transfer. Shared_ptr In the Boost library is a
C ++ auto_ptr smart pointer and auto_ptr smart pointer

In the header file memory, this type is imported through # include
Usage:
Auto_ptr
For example, if the type is int, the specific definition is as follows:

Sorry, it has never been updated since the last smart UI introduction series. We planned to complete the smart UI website, API, and demo in one week, only when the results are written can we find that there is not much content. When developing websites and writing APIs, we also found a lot of optimizations, so we made a wide range of Optimizations to the framework. The website is now available at http://sma
Smart pointers address the issue of resource lifetime management (especially dynamically allocated objects). Smart pointers are available in a variety of different styles. Most have a common key feature: automatic resource management. This feature may appear in different ways: such as the lifetime control of dynamically allocated objects, and the acquisition and release of resources (files, network Connecti
