Using custom dll in Qt Application

问题

First, my compiler and OS:

• Qt Creator 1.3
• Qt 4.6 (32 bit)
• Windows 7 Ultimate

I want to learn how to create and import a dll in Qt. I've created a *.dll file using Qt Creator, called Shared1.dll which contains nothing but an empty class named Shared1. Now I'd like to use Shared1 class in another Qt project. How can I do that?

Thanks in advance.

Use your Pro file to include your header files and libraries..

For Header Files:

INCLUDEPATH += "C:\Source\HeaderFiles"

For libraries:

LIBS += "C:\Source\Libraries\MyLib.lib"

Include those header files while using the functions from the libraries.

This works for me... Try it..
