Layout Inheritance

[IknowQT]

I want to define the basic ui form and inherit it and use it in all future widgets. Can you see if I did it right?

class QWidgetBase : public QWidget
{
	Q_OBJECT

private:
	Ui::QWidgetBase		ui;
	QCustomTitleBar*	m_TitleBar;
	QWidget*			m_pParent;
	QPushButton*		m_baseBtn;

public:
	QWidgetBase(QWidget *parent = Q_NULLPTR);
	~QWidgetBase();

	void	BaseInitialize();
	void	SetContentsWidget(QWidget* widget);
};

QWidgetBase::QWidgetBase(QWidget *parent)
{
	ui.setupUi(this);
	
	m_pParent = parent;
	BaseInitialize();
}

QWidgetBase::~QWidgetBase()
{
}

void QWidgetBase::BaseInitialize()
{
	m_TitleBar = new QCustomTitleBar(this);
	m_TitleBar->SetVisibleButton(false, false);
	m_TitleBar->SetVisibleButton(true, false);

	this->ui.base_VL_titlebar->addWidget(m_TitleBar);	
}

void QWidgetBase::SetContentsWidget(QWidget* widget)
{
	QMainViewer* p = qobject_cast<QMainViewer*>(m_pParent);
	this->ui.widget = p;
}


/**************************************************************************************/
class QMainViewer : public QWidgetBase
{
	Q_OBJECT
private:
	Ui::QMainViewer		ui;
	QWidget*			m_pParent;
	QCustomTitleBar*	m_pTitlebar;

public:
	QMainViewer(QWidget* parent = Q_NULLPTR);
	QMainViewer(QSize size, QWidget* parent = Q_NULLPTR);
	~QMainViewer();

	void	InitailizeVariable();
	void	InitailizeCtrl();
	void	LayoutProperty();

public slots:
	void	BtnLoginClicked();
	void	BtnIncubateClicked();
	void	BtnMethodClicked();
	void	BtnOpenMethodClicked();
	void	BtnSettingsClicked();
};
