创建采用自定义类的成员函数的问题

有一个类继承了QGroupBox（不知道有没有关系），还有一个类就是简单的为他们存储数据和几个函数。我需要将第二个类的实例传递给第一个类的方法。

MattyGroupBox.h

#ifndef MATTYGROUPBOX_H
#define MATTYGROUPBOX_H

    public QGroupBox
{
public:
    MattyGroupBox();
    //void fillFrame(MattyNote & ThisNote);
    ~MattyGroupBox();
private:
    void buildFrame();
    QLabel* NoteTitleLabel;
    QLabel* NoteTypeLabel;
    QLabel* NoteCrTimeAndDateLabel;
    QLabel* NoteEventTimeAndDateLabel;
    QLabel* NoteTextLabel;
    QSpacerItem* horizontalSpacer_1;
    QSpacerItem* horizontalSpacer_2;
    QSpacerItem* verticalSpacer;
    QPushButton* editNoteButton;
    QPushButton* deleteNoteButton;
    QHBoxLayout* horizontalLayout_1;
    QHBoxLayout* horizontalLayout_2;
    QVBoxLayout *verticalLayout;
    QGridLayout *gridLayout;

};

#endif // MATTYGROUPBOX_H

MattyGroupBox.cpp

#include "stdafx.h"
#include "MattyGroupBox.h"
#include "MattyNote.h"


MattyGroupBox::MattyGroupBox()
{
    buildFrame();
}

//void MattyGroupBox::fillFrame(MattyNote & ThisNote)
//{
    //NoteTitleLabel->setText(ThisNote.getTitle());
    //NoteTypeLabel->setText(ThisNote.getType());
    //NoteTextLabel->setText(ThisNote.getText());    
//}

void MattyGroupBox::buildFrame()
{
    // тут очень много того, из-за чего потребовалось наследовать класс
    // добавление элементов Qt

}

MattyGroupBox::~MattyGroupBox()
{
    delete NoteTitleLabel;
    delete NoteTypeLabel;
    delete NoteCrTimeAndDateLabel;
    delete NoteEventTimeAndDateLabel;
    delete NoteTextLabel;
    delete horizontalSpacer_1;
    delete horizontalSpacer_2;
    delete verticalSpacer;
    delete editNoteButton;
    delete deleteNoteButton;
    delete horizontalLayout_1;
    delete horizontalLayout_2;
    delete verticalLayout;
    delete gridLayout;
}

如果取消注释该方法，则会出现错误：

Error   C2511   'void MattyGroupBox::fillFrame(MattyNote &)': overloaded member function not found in 'MattyGroupBox'
Error   C2061   syntax error: identifier 'MattyNote'

stdafx.h 根本不包含标头，Constants.h、DbManager.h、MattyTime.h 和它们的 cpp 也不会发送到任何地方。

实际上，这里可能有什么问题？一般来说，该项目有 10 个头文件和代码文件，如果您需要其他内容，我会发布。
