Qt-creator 使用 dll

Question

How to access to functions in given DLL in Qt?

Answer 1

You have to include the header file for the DLL in your source file, of course:

#include "MyDll.h"

Then, in the .PRO file, just add:

LIBS += MyDll.dll

Answer 2

You can use the Qt class "QLibrary". You can find a detailed description and examples at http://doc.trolltech.com/4.7/qlibrary.html

The main idea is, that you define a function pointer, assign it with QLibrary::resolve to the function in the dll, and you can then call it normally as any function.
