글쎄, 당신 코드를 표시하는 것이 좋습니다, supose입니다 :

main.h

#ifndef MAIN_H 
#define MAIN_H 

#include <QtWidgets/QApplication> 
#include <QtCore/QDebug> 
#include <QtGui/QIcon> 
#include <QtWidgets/QSystemTrayIcon>

#include <QtWidgets/QMenu> 
#include <QtWidgets/QWidgetAction> 
#include <QtWidgets/QPushButton> 
#include <QtWidgets/QHBoxLayout> 
#include <QtWidgets/QSpinBox> 
#include <QtWidgets/QLabel> 

class SpinBoxAction : public QWidgetAction 
{ 
public: 
    SpinBoxAction (const QString& title) : QWidgetAction (NULL) 
    { 
     QWidget* Widget = new QWidget (NULL); 
     QHBoxLayout* Layout = new QHBoxLayout(); 
     QLabel* Label = new QLabel (title); 
     Layout->addWidget (Label); 
     SpinBox = new QSpinBox(NULL); 
     Layout->addWidget (SpinBox); 
     Widget->setLayout (Layout); 

     setDefaultWidget(Widget); 
    } 

    QSpinBox* spinBox() 
    { 
     return SpinBox; 
    } 

private: 
    QSpinBox* SpinBox; 
}; 

class Reciever : public QObject 
{ 
private: 
    QSystemTrayIcon* trayIcon; 
public: 
    Reciever() 
    { 

    } 
    void setup(QSystemTrayIcon* trayIcon) 
    { 
     this->trayIcon = trayIcon; 
    } 

    Q_OBJECT 
public slots: 
    void action(int i) 
    { 
     trayIcon->showMessage("changed", "spin box value has been changed", QSystemTrayIcon::NoIcon, 1000); 
    } 

    void onActivated(QSystemTrayIcon::ActivationReason reason) 
    { 
     trayIcon->showMessage("activated", "tray icon has been activated", QSystemTrayIcon::NoIcon, 1000); 
    } 
}; 

#endif // MAIN_H

    QMenu* menu = new QMenu(); 
    SpinBoxAction* spinBoxAction = new SpinBoxAction("Action Title");

    QObject::connect(spinBoxAction->spinBox(), SIGNAL(valueChanged(int)), reciever, SLOT(action(int))); 

    trayIcon->setContextMenu(menu); 
    trayIcon->setVisible(true);
