How to connection serialport outside 'mainwindow.cpp' ?

[bknhatice]

Hi,

I created new MainWindow project. I don't want to do the serialport connection via mainwindow.cpp. But when I want to make a serialport connection over a different class, the project crashes.

Example:
cameramodel.h
#include <QtSerialPort/QSerialPort>
#include <QtSerialPort/QSerialPortInfo>
class CameraModel : public QMainWindow
{
Q_OBJECT

public:
QSerialPort *serialCamera;
bool isCameraSerial = false;

}

cameramodel.cpp:
#include "cameramodel.h"
#include "ui_cameramodel.h"

CameraModel::CameraModel(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::CameraModel)
{
ui->setupUi(this);
serialCamera = new QSerialPort(ui->cb_spCportName->currentText());
serialCamera->setBaudRate(9600);
serialCamera->setDataBits(QSerialPort::Data8);
serialCamera->setParity(QSerialPort::NoParity);
serialCamera->setStopBits(QSerialPort::OneStop);
serialCamera->setFlowControl(QSerialPort::NoFlowControl);
if (serialCamera->open(QIODevice::ReadWrite))
{
QMessageBox::information(this, tr("Connected"), "Serial Port Opened Successfully");
}
else{
QMessageBox::critical(this, tr("Error"), serialCamera->errorString());
}
}
Project crashed. How to solve ?

Thanks,

Project crashed

Use a debugger and see where it crashes, fix the crash.

ui->cb_spCportName->currentText()

What is the format of the port name?
Are you using proper port name format?
