    ok didnt check it lately , i assume its because the NewSize from event has not yep been applied.

    I think i get your use case now
    the button show sort of go to next col if there is no room to be below.
    So its not on top of the other but on top in new col?
    like this

      you can use
      const QSize &QResizeEvent::oldSize() const
      const QSize &QResizeEvent::size() const
      to check what size window has and had.

      Based on those numbers , you can do the right thing, store button pos
      or to restore the button to old pos.

      you can use qDebug() << "size" << event.oldSize() << " to " << event.Size();

      to get an idea of what numbers you will see.

      You can use
      http://doc.qt.io/qt-5/qdesktopwidget.html#availableGeometry

      to get how big screen is.

          @Apeksha Like this maybe?

          ui->pushButton->move(oldX, oldY);

            I have used the same, but it's not working.

            void MainWindow::resizeEvent(QResizeEvent* event)
            {
            qDebug() << "old size" << event->oldSize() << " to " << event->size();
            int oldx,oldy;
            oldpos=ui->pushButton->geometry();
            oldx=oldpos.x();
            oldy=oldpos.y();
            qDebug()<<"oldpos x is"<<oldx<<"oldpos y is:"<<oldy;
            if (!firstTime) {
            ui->pushButton->move(50,100);
            }

                else {
                     ui->pushButton->move(oldx,oldy);
                       firstTime = false;
            
                }
            
                QMainWindow::resizeEvent(event);
            

            }

              @Apeksha "it's not working" doesn't help to solve the problem.
              Did you analyse why it is not working? You can print out the values oldX, oldY for example.

                    @Apeksha Your current resizeEvent is wrong: you read CURRENT button geometry and use it as OLD geometry! You need to store the old posx/posy before and restore it later when needed.

                      K i uderstood , Initially I will save oldx and oldy in constructor and where actually i have to use this oldx and oldy to restore. In above code If I use this oldx and oldy , its not restoring. I am attaching code:

                      void MainWindow::resizeEvent(QResizeEvent* event)
                      {
                      if (!firstTime) {
                      ui->pushButton->move(50,100);
                      }

                          else {             
                              ui->pushButton->move(oldx,oldy);  ---->This oldx and oldy Iam  storing in constructor.
                                 firstTime = false;
                          }

                            I think, Problem seems to be with enabling of flag "firsttime".

                            CAN YOU TRY THIS?

                            int oldX,oldY,fstFlag=1;

                            void MainWindow::resizeEvent(QResizeEvent *event)
                            {
                            if(!fstFlag)
                            {
                            oldX=0;
                            oldY=0;
                            fstFlag=1;

                            oldX=50;
                            oldY=100;
                            }
                            ui->pushbutton->move(oldX,oldY);
