Having fixed size for dynamically created buttons!

[Kushan]

In my qt c++ application buttons are created dnamically! When the number of buttons are different the size of the buttons are also diffrent! I want to have a fixed size for the buttons!

void NewOrders::on_pushButton_clicked(){

QString LIst;
List<<"Hello"<<"John";

for(int i=0;i<List.size();i++){
QString Name= QString::number(i);
f3 = new QFrame();
c= new QPushButton();
c->setText("Set "+List[i]);
c->setObjectName("Button"+Name);
ui->horizontalLayout->addWidget(c);

}
}

Here 2 buttons are created since List has 2 elements! But if I insert another element to the List 3 buttons are created but the size of a button in the 2 situations is different! How can I have a fixed size for the buttons for both the situations?

f3 = new QFrame();

How can I have a fixed size for the buttons for both the situations?

c->setSizePolicy(QSizePolicy::Fixed,QSizePolicy::Fixed);
