QSerialDevice problem to start in GUi

**ssaku** · 2nd December 2010, 15:59

Hi, my problem is to use the QSerialDevice in my Gui. Functions,constructors they are need QObject "parameters" but in my class in constructor I have QWidget

Qt Code:

Switch view

#include "src/qserialdeviceenumerator/serialdeviceenumerator.h"
 
canteen::canteen(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::canteen)
{
    this->m_sde= new SerialDeviceEnumerator(this);
 
    ui->setupUi(this);
 
}

#include "src/qserialdeviceenumerator/serialdeviceenumerator.h"

canteen::canteen(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::canteen)
{
    this->m_sde= new SerialDeviceEnumerator(this);

    ui->setupUi(this);

}

To copy to clipboard, switch view to plain text mode

when i build ... is ":: error: collect2: ld returned 1 exit status"
And I have a few questons
1.Is it posible to use QSerialDevice in Gui ??
2. Can anybody could help ??
Sorry for my english
