    Hi
    If you place a QLabel on the button, it would be hidden with the button :(
    So you issue is that when you flash the permission button, the layout moves
    the other buttons?

        Hi,

        button1 PermissionButton button2

        when the permissionButton is hide ,button1 and button2 is moving towards each other.I know this is normal.,but permissionButton have to flash in a specific time,and in during this time when the permission button is flashing ,user always can't see permissionButton's Text .I am doing it in C# like that.I put a label on permissionButton and I click in settings for label,set to background and so that if the permissionButton is hide, in this case label shows up.

          Oh, so the flashing of buttons is done by hide/show hide/show ?
          And it might be stopped in hide ?
          Sounds like you should rather flash text on button so it cant be hidden.
          It will be awful complicated if you use layouts as you cant have widgets on top of each other.
          So i would find a better flashing method.

          One can't do it using the designer, true. But you can stack widgets on top of each other in a Gridlayout:

          QGridLayout *gLayout = new QGridLayout(this);
          gLayout->addWidget(new QLabel("text below the Button",this),0,0);
          gLayout->addWidget(new QPushButton("Buttontext",this),0,0);
          

          this actually should help the OP, has because hiding the button will not cause a resize of the layout, as the label is still in the cell and being drawn

                Guys this is good solution but I am using ui , so that this is giving me a new object.Any better option?

                  that should be easy enough, instead of creating a new QGridlayout, you reference the one you created in your UI-file (via Designer)

                  //Assuming you placed already  a QPushbutton in your Gridlayout via Designer
                  
                  QGridLayout *gLayout = ui->GridLayoutObjectName;
                  gLayout->addWidget(new QLabel("text below the Button",this),0,0);

                      Hi
                      If they dont overlap, check that the button is in fact at 0,0
                      it works here

                          Hi
                          If they still move a bit, its due to QLabel being other size that QButton

                          
                            QGridLayout* gLayout = ui->gridLayout;
                            QLabel *lab = new QLabel("text below the Button", this);
                            lab->setSizePolicy( ui->pushButton->sizePolicy() ); // use fixed
                            lab->setMinimumHeight(23); // same height
                            gLayout->addWidget(lab, 0, 0);
                            QTimer* tim = new QTimer(this);
                            connect (tim, &QTimer::timeout, [this]() {
                              (this->ui->pushButton->isVisible()) ? this->ui->pushButton->hide() : this->ui->pushButton->show();
                            });
                            tim->start(1000);
                          

                          result:
                          alt text

                            @ZekDe I said previously that this trick only works with a QGridLayout if you call addwidget to a horizontal layout, that will always append the widget!
