Adding multiple text field in a Qt pushButton element - c++

Question

I am trying to implement a Qt push button and some of its properties are going to change under certain circumstances, such as the size, the color and the text field. While I have implemented most of the functionality, I'm looking to add (probably) another text field at a custom place over the button which is going also to change according to different input. For example:
Desired button layout
In this example, I want to be able to change dynamically both the numeric value and the currency. Is there a way to do it, or something similar?
EDIT: I tried to derive my button class from QPushButton and add some extra text in it, but with no luck. Below you'll find the relevant code:
.h file:
namespace Ui {
class myButton;
}
class myButton : public QPushButton
{
Q_OBJECT
public:
explicit myButton(QWidget *parent = 0);
~myButton();
void setSize(int _xs, int _ys);
void setPosition(int _xp, int _yp);
private:
Ui::Tile *ui;
int xSize = 95;
int ySize = 95;
protected:
void paintEvent(QPaintEvent *);
};
.cpp file
myButton::myButton(QWidget *parent) :
QPushButton(parent),
ui(new Ui::myButton)
{
ui->setupUi(this);
}
myButton::~myButton()
{
}
//Paint event of button
void myButton::paintEvent(QPaintEvent *paint){
QPushButton::paintEvent(paint);
QPainter p(this);
p.save();
p.drawText(QPoint(80,10),"FirstName"); // Simple Text.
p.setPen(Qt::blue); // Changing the color of pen.
p.setFont(QFont("Arial", 50)); // Changing the font.
p.drawText(QPoint(80,20),"MiddleName");
p.drawText(QPoint(80,30),"Lastname");
p.restore();
}
Then I'm calling my new button with something like:
myButton *newBtn2 = new myButton(this);
newBtn2->show();
