QObject::connect: Cannot connect (null)::pressed to MainWindow::handleExecutionButton()

[barzaka12]

Hello,
I get these 2 errors on build and have no idea why:

QObject::connect: Cannot connect (null)::pressed to MainWindow::handleExecutionButton()
QObject::connect: Cannot connect (null)::pressed to MainWindow::handleAbortButton()

Here's a snippet of the code where the connect part is:

#include "mainwindow.h"
#include "ui_mainwindow.h"

Ui_MainWindow *form = new Ui_MainWindow();

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);


    QObject::connect(form->startButton, SIGNAL (pressed), SLOT (handleExecutionButton()));
    QObject::connect(form->stopButton, SIGNAL (pressed), this, SLOT (handleAbortButton()));
}

You are my last hope. Thank you in advance!

Hi,

What is that ???

Ui_MainWindow *form = new Ui_MainWindow();

try:

connect(ui->startButton, SIGNAL (pressed()), SLOT (handleExecutionButton()));
