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

        QMainWindow::resizeEvent(event);
    

    }

    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 :)

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

              I second that. I'm so curious, pretty please with sugar on top, explain your use case.

                ui->contentWidget->setStyleSheet("QWidget {background-color:#C0C0C0;}");
                ui->contentWidget->setMinimumSize( 820, 150 );
                QHBoxLayout *ConfigurationLayout = new QHBoxLayout;
                QScrollArea *scrollArea = new QScrollArea;
                // scrollArea->setStyleSheet("QScrollArea {background-color:#C0C0C0;}");
                scrollArea->setVerticalScrollBarPolicy(Qt::ScrollBarAsNeeded);
                scrollArea->setHorizontalScrollBarPolicy(Qt::ScrollBarAsNeeded);
                scrollArea->setWidget(ui->contentWidget);
                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?

                        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?

                                @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)
                                        {

                                          @Apeksha Did you verify the else block was executed? Did you check the oldx/oldy values?
