Set to background Button on Label like C#

It will be awful complicated if you use layouts as you cant have widgets on top of each other.

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

@J.Hilk
Oh, Gridlayout allow that. i had no idea :)
Well that is then ;)

Even i would still make it flash some way. :)

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

@ZekDe
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);

Label and button must overlap.This is problem.I am already adding it in ui ,this is different I am using in code platform,but same thing.

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

CODE
QGridLayout *gLayout = ui->gridLayout;
gLayout->addWidget(new QLabel("text below the Button",this),0,0);
RESULT

[ZekDe]

ui->horizontalLayout->addWidget(ui->DKCS_btn1);
ui->horizontalLayout->addWidget(new QLabel("text below the Button",this,0),0,0);

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:

@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!
