c++ - Incorporate setText and setNum into a label in Qt? -

-

i have few simple lines of code of slot horizontal slider: 

void newwindow::on_horizontalslider_valuechanged(int value) {     ui->label->setnum(value); }

now, instead of label displaying number (such "11" or "42"), how make display "value: 11"?

i think have incorporate settext too, although don't know how that.

there's simple solution haven't found yet. help?

use qstring::number convert int qstring :

 ui->label->settext(qstring("value: ") + qstring::number(value));
