Qt string problems - c++

Question

So I made a program that simply makes "random" sentences. It chooses a noun and a color adjective from a list of 7 based to a seed that uses ctime. Now I'm trying to convert it into a console app. My issue is that I'm not able to display it correctly. Instead of cout I need to get it all on one label.
error: no matching function for call to
'QLabel::setText(std::string&)'
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <cstdlib>
#include <iostream>
#include <ctime>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_newSentence_clicked()
{
std::string noun[7] = {"cow", "tree", "marker", "cereal", "calendar", "rug", "hammer"};
std::string color[7] = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"};
srand(time(0));
int nounRandomizer = (rand()%5);
int colorRandomizer = ((rand()+1)%5);
std::string sentence = "The"+noun[nounRandomizer]+" is "+color[colorRandomizer]+".";
ui->sentenceDisplay->setText(sentence);
}

Answer 1

From QLabel reference, setText function takes const QString& as input parameter, but you passed in std::string. you could construct a QString object from std::string then pass to it.
For example:
ui->sentenceDisplay->setText(QString::fromStdString(sentence));
