Label with text and number

Hey,
I have a Label and I want to put in a number and a text.

Code:

---

int a;
ui->label->setText(a "is the answer");

---

but this does not work, because qt can not see a there as a number. Maybe someone can help me?

Also when I want the label to say a over b I would write "a/b" and use

Code:

---

int a;
int b;
ui->label->setNum(a/b);

---

But obviously it calculates the result. I think it would also be possible if I could put Numbers in the setText function.

Look at the QString::arg() methods for formatting strings with extra arguments.

Code:

---

int a = 42;
QString formattedString = QString( "%1 is the answer to life, the universe, and everything" ).arg( a );

---

Cracking open a C++ textbook would help you, too. You should realize that

Code:

---

ui->label->setText( a "some string" );

---

isn't correct C++ syntax.
