    @Apeksha I don't know who you're going to position this button. What is the logic for positioning it?

      @jsulm Same thing I was confused, Now If my gui is of 500,500(width,height), If i resized it to some 300,400 then button position will change. Now my doubt is if gui is maximized i.e to original size(500,500), how to move buttonto original position?

          @Apeksha

          you can just store its old position ?

          QRect oldpos; // int the class

          void MainWindow::resizeEvent(QResizeEvent* event)
          {
              qDebug("ResizeEvent");
              if (!firstTime) {
               oldpos=ui->pushButton->geometry();
                  ui->pushButton->move(0,0);
              } else {
                  firstTime = false;
              }
              QMainWindow::resizeEvent(event);
          }

            @Apeksha I still don't understand why you position this button manually...

              QMainWindow::resizeEvent(event);
              }

              Here we are saving old geometry, again where we set this geometry?

                  }

                  But it's not working, button is not moving to old position again when gui is maximized.

                    But that is impossible for it to know.
                    You must check for that situations then. and then call the
                    ui->pushButton->move(oldx,oldy);

                    you can use isMaximized()

                    I wish i understood why you cant just use a layout :)

                        Not wrong as such, but you seem to except it can guess your thoughts :)

                        The resizeEvent is called when ever windows size has changes.

                        If you want to do anything , you must make the logic your self.

                        if you want to restore the button when maximized you can test with
                        isMaximized() to see if that is now. and if yes, then
                        move it back to old spot wtih ui->pushButton->move(oldx,oldy);

                        The firstTime flag only fixed the situation that you didnt not want to move it on first resize (first time shown)

                        If you want to move it back then when maximized you need some code for that too :)

                                scrollArea->setWidgetResizable(true);
                                ConfigurationLayout->addWidget(scrollArea);
                                mainBoxLayout->addLayout(ConfigurationLayout);

                                This is my part of code where button movable is required, I had widget and scrollArea and some buttons.
                                So when my app is minimized, one of the button position should change, when gui is minized it have to display on top of widget. I hope you got my requirement.

                                    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.

                                          I understood saving of old position and new position, but how to restore i.e hoe to set button old position to restore?
