      @hjohn
      for creating a shared library see this.
      In the QWidget then overrride mousePressEvent() handler to react to mouse clicks and do some stuff.

          Yes it is possible. A dll with GUI is no different than one without, just follow @raven-worx's link and read the docs on how to create a shared library.

          Read and abide by the Qt Code of Conduct

              I am using centOS .
              I have added my .so file into particular debug folder of project in which i want to use.

              :-1: error: error: /home/local/build-TestDll-Desktop_Qt_5_5_1_GCC_64bit-Debug/libMyLib.so: No such file or directory
              

              i have already added .so file in that path.If i run this project in windows (after changing files path).It works properly.

                @hjohn Your original question was how to create a shared library. Now you say you added it already. So, what do you actually want to do? And why do you manually put your library to the build directory?!

                  @jsulm
                  Yes , I created a library after asking the original question, just for learning purpose.
                  Now I'm running it on windows , and it works but when I try to do the same in Linux, its displaying that error message.
