Nested Layout

Hi,
I use a nested layout widget instance in my subclass of QMainWindow. At runtime I get the following message on console:

QLayout: Attempting to add QLayout "" to SchulungsplanParentWidget "", which already has a layout

Do you know why ? The gui seems to be correct...

This is my constuctor of the Widget class which is the center in my QMainWindow:

Code:

---

SchulungsplanParentWidget::SchulungsplanParentWidget(QDate& p_startViewDate, QDate& p_endViewDate, QWidget *p_parent)
	: QWidget(p_parent)
{
	QVBoxLayout *vBoxLayout = new QVBoxLayout(this);
	QHBoxLayout *hBoxLayout = new QHBoxLayout(this);
 
	m_startViewDateLabel= new QLabel("Schulungsplan VON:");
	m_startViewDateEdit = new QDateEdit(p_startViewDate);
	m_endViewDateLabel	= new QLabel("Schulungsplan BIS:");
	m_endViewDateEdit  	= new QDateEdit(p_endViewDate);
	m_uebernehmenButton = new QPushButton("Uebernehmen");
 
	m_spTableView 		= new SchulungsplanView(this);
 
	hBoxLayout->addWidget(m_startViewDateLabel, 1, Qt::AlignLeft);
	hBoxLayout->addWidget(m_startViewDateEdit, 2, Qt::AlignLeft);
	hBoxLayout->addWidget(m_endViewDateLabel, 1, Qt::AlignLeft);
	hBoxLayout->addWidget(m_endViewDateEdit, 2, Qt::AlignLeft);
	hBoxLayout->addWidget(m_uebernehmenButton, 1, Qt::AlignLeft);
 
	vBoxLayout->addLayout(hBoxLayout);
	vBoxLayout->addWidget(m_spTableView);
 
	connect( m_uebernehmenButton, SIGNAL(clicked() ),
				this, SLOT(uebernehmenButtonPressed() ) );
}

change lines 4 , 5 as -

Code:

---

QVBoxLayout *vBoxLayout = new QVBoxLayout();
QHBoxLayout *hBoxLayout = new QHBoxLayout();

---

and add to line 23

Code:

---

setLayout(vBoxLayout);

---

Hope it helps :)

ok ;-) thank you... so it works:

Code:

---

SchulungsplanParentWidget::SchulungsplanParentWidget(QDate& p_startViewDate, QDate& p_endViewDate, QWidget *p_parent)
	: QWidget(p_parent)
{
	QVBoxLayout *vBoxLayout = new QVBoxLayout(this);
	QHBoxLayout *hBoxLayout = new QHBoxLayout();
