Simple Question about how to put an int to a function that requires coonst QString.

[hakermania]

QProgressbar Format can be set as follow:

progressbar->setFormat("text here");

progressbar->setFormat("text here");

To copy to clipboard, switch view to plain text mode 

What I want is to have some text into the setFormat(); and an integer t follow.
Specifically, I need

ui->progressbar->setFormat("Starting with " + ui->listwidget->count()+ " files");

ui->progressbar->setFormat("Starting with " + ui->listwidget->count()+ " files");

To copy to clipboard, switch view to plain text mode 

I get error

invalid operands of types ‘const char*’ and ‘const char [7]’ to binary ‘operator+’

invalid operands of types ‘const char*’ and ‘const char [7]’ to binary ‘operator+’

To copy to clipboard, switch view to plain text mode 

So, how will I do what I want?

Thx for any replies, happy new year.
