    Hi,
    I am using this resizeevent, but it is calling when binary runs.
    void MainWindow::resizeEvent(QResizeEvent* event)
    {
    qDebug("ResizeEvent");
    ui->pushButton->move(0,0);
    QMainWindow::resizeEvent(event);
    }

    hi

    • but it is calling when binary runs.

    Yes, is that not what you asked for ?
    Events only works when app is running.

    Do you mean in Designer ?

        Sorry i do not understand what is wrong.

        The resizeEvent will be called when user resize the running app.

        Are you talking about inside Designer part, where you do widget design or where do you mean?

        is your widget a Designer plugin ?

          Hi,

          You have said when resize event is used, it calls when user resize the running app.

          So I have done when user user resizes the app, then button have to move its Y axis, so i have written my code as follows:
          void MainWindow::resizeEvent(QResizeEvent* event)
          {
          qDebug("ResizeEvent");
          ui->pushButton->move(0,0);
          QMainWindow::resizeEvent(event);
          }

          But when my is running, without resizing app, button position is changing, my requirement is when user resizes app then only button position i.e, y-axis have to change, I hope you got my point

            @Apeksha Why do you position the button manually? Why not just use layouts?

                Ahhh, now i understand.
                Well, there is no way to tell if done by system at start up or by the user.
                But should it not do the same ?
                Or only if size is smaller then the start size or ? what is the rule?

                    Hi
                    resizeEvent(event) is the way to do it.
                    You just need to make sure then you do not react to the first resize events you get when app starts up.

                      Hi,

                      I am using resizeevent , but my button is moving initially when app runs, but it have to move when I resize my gui.
                      void MainWindow::resizeEvent(QResizeEvent* event)
                      {
                      qDebug("ResizeEvent");
                      ui->pushButton->move(0,0);
                      QMainWindow::resizeEvent(event);
                      }
                      this is the way I am doing, any correction?

                        @Apeksha

                        That is fine. but you will also do on first resize
                        to avoid that, make some if statements
                        the event has both oldSize and newSixe to check

                        I cannot tell you what to write as i dont know
                        what the rules are to move the button.
                        At what sizes etc.

                        You can also use a timer to only allowed after say 10 secs to
                        avoid doing it on first resize.

                            @Apeksha Just add a boolean variable to your class and set it to false in the resizeEvent:

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

                                @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?

                                      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);
                                      }

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

                                          @mrjj

                                          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);
                                          }

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