In your library project file, use TEMPLATE=lib. If you want a create a shared library use CONFIG += dll, and if you want to create a static library use CONFIG += staticlib.

Once the library is created, you can use LIBS += -L searchpath -l libname in your main application project file (see Qt docs). Be sure to #include the header file for your library....

suppose i in my library project file i use TEMPLATE = lib .
now i want to create lib file then i have to give
#qmake project file
# make
if it will successfully compile then it will build .lib file
this is right or not.
and where i have to locate the lib file

I'm working on using QT's plugin system to create libraries for my software. Here is the link to the doc section that talks about QT Plugins:

http://doc.trolltech.com/4.3/plugins-howto.html

Here is a post I made earlier with sample code for a plugin:
http://www.qtcentre.org/forum/f-qt-p...ghlight=plugin

*Note: You will need to fix the createWidget declaration in interface.h by making it a pure virtual function, like wysota was saying :).

Honestly, after reading through the plugin page, going over the paint example in the docs and creating a sample, it is really easy to extend your app through the QT Plugins.

Is it possible to convert it for qtcreator 1.3 ????
