pay attention to a small thing in cross platform programming [复制链接]

If you use Qt, often it means that you are developing cross platform applications. One thing that can annoy you and your customers is that your code works on one platform and does not work on another one. One little evil is that your variables are not initialized automatically(on some platforms) and set to junk which can bring your code down. Therefore, a good habit is that always initialize all your variables with some values which make some senses. It is hard to find this type of bugs. In this way you can save a lot of time.

Two places:
1. initialize all class variables in constructors
2. initialize all functions variables where they are defined.

You will not hate it if you do it. Especially on Windows.

有机会试一下这个问题
