change layout dynamicly

[stella1016]

Hi,

I have problem when change the layout dynamicly.
The layout seems not be changed.

I had a look for the example already. But in my case it doesn't work. I post my code here:

One and the only one method in constructor:

void xyzWidget::create(bsDoubleMode mode, double minimum, double maximum, bool periodic, bool horizontal)
{
	setSizePolicy(QSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred));
	if(horizontal)
		setLayout(new QHBoxLayout(this));
	else
		setLayout(new QVBoxLayout(this));
 
	layout()->setMargin(0);
 
	w_xyzGroupBox = new QGroupBox(this);
	w_xyzGroupBox->setSizePolicy(QSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred));
	if(horizontal)
		w_xyzGroupBox->setLayout(new QHBoxLayout(w_xyzGroupBox));
	else
		w_xyzGroupBox->setLayout(new QVBoxLayout(w_xyzGroupBox));
	w_xyzGroupBox->hide();
 
	w_xValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_xValue->setLabel(tr("X :"));
	w_xValue->setLabelColor(QColor(200, 0, 0));
	connect(w_xValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_xValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_xValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_xValue);
 
	w_yValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_yValue->setLabel(tr("Y :"));
	w_yValue->setLabelColor(QColor(0, 200, 0));
	connect(w_yValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_yValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_yValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_yValue);
 
	w_zValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_zValue->setLabel(tr("Z :"));
	w_zValue->setLabelColor(QColor(0, 0, 200));
	connect(w_zValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_zValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_zValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_zValue);
}

void xyzWidget::create(bsDoubleMode mode, double minimum, double maximum, bool periodic, bool horizontal)
{
	setSizePolicy(QSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred));
	if(horizontal)
		setLayout(new QHBoxLayout(this));
	else
		setLayout(new QVBoxLayout(this));

	layout()->setMargin(0);

	w_xyzGroupBox = new QGroupBox(this);
	w_xyzGroupBox->setSizePolicy(QSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred));
	if(horizontal)
		w_xyzGroupBox->setLayout(new QHBoxLayout(w_xyzGroupBox));
	else
		w_xyzGroupBox->setLayout(new QVBoxLayout(w_xyzGroupBox));
	w_xyzGroupBox->hide();

	w_xValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_xValue->setLabel(tr("X :"));
	w_xValue->setLabelColor(QColor(200, 0, 0));
	connect(w_xValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_xValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_xValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_xValue);
	
	w_yValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_yValue->setLabel(tr("Y :"));
	w_yValue->setLabelColor(QColor(0, 200, 0));
	connect(w_yValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_yValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_yValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_yValue);
	
	w_zValue = new bsDoubleWidget(this, mode, minimum, maximum, periodic);
	w_zValue->setLabel(tr("Z :"));
	w_zValue->setLabelColor(QColor(0, 0, 200));
	connect(w_zValue, SIGNAL(valueChanged(double)), this, SLOT(xyzChanged(double)));
	connect(w_zValue, SIGNAL(editingBegin()), this, SIGNAL(xyzEditingBegin()));
	connect(w_zValue, SIGNAL(editingFinished()), this, SIGNAL(xyzEditingFinished()));
	layout()->addWidget(w_zValue);
}

To copy to clipboard, switch view to plain text mode 

After I push a button, it is supposed to change the layout by calling this method:

void xyzWidget::setLayoutVertical()
{
	layout()->removeWidget(w_xValue);
	layout()->removeWidget(w_yValue);
	layout()->removeWidget(w_zValue);
 
	setLayout(new QVBoxLayout());
	w_xyzGroupBox->setLayout(new QVBoxLayout(w_xyzGroupBox));
 
	layout()->addWidget(w_xValue);
	layout()->addWidget(w_yValue);
	layout()->addWidget(w_zValue);
}

void xyzWidget::setLayoutVertical()
{
	layout()->removeWidget(w_xValue);
	layout()->removeWidget(w_yValue);
	layout()->removeWidget(w_zValue);

	setLayout(new QVBoxLayout());
	w_xyzGroupBox->setLayout(new QVBoxLayout(w_xyzGroupBox));

	layout()->addWidget(w_xValue);
	layout()->addWidget(w_yValue);
	layout()->addWidget(w_zValue);
}

To copy to clipboard, switch view to plain text mode 

(The groupbox will not be used any way)

Anyone can help?

I searched a little bit here. QStackedWidget was mentioned in several threads.
But since I don't switch back and force between two widgets, I don't see the necessarity to use QStackedWidget. You will probably ask me why not change the value during initialization. I just need this switch one time.
