          Hi and welcome to devnet,

          Since you are using widgets in your project, did you add

          @QT += widgets@

          in your pro file ?

                          Hi.
                          if you want to run your exe then just copy and paste from -C:\Qt\4.8.4\bin- ..../Qt/5.x/bin folder Qt5core.dll file.
                          hope this helps.

                          Edited@IamSumit :)

                            Also, you won't find Qt 5 DLLs in a Qt 4.8 folder ;)

                              I don't know in which version it started, but Qt has a windows deployment tool. I recently wrote up a "blog entry on it":http://bit.ly/qt5deploy. I found it worked quite well at gathering up all the .dlls needed to deploy an application.

                                    I have three methods implemented in my project with tables.. I want that if user gives input to the table of first methods. Same inputs are copied to the
                                    table of second and third methods. How to do that?

                                      http://www.cplusplus.com/reference/iomanip/setprecision/

                                      Anyway, I think you should post the question in other forum.
