QItemDelegate Align

[spirit]

wrong code. try this

QWdiget *w = new QWidget(parent);
MyDoubleSpinBox2 *editor = new MyDoubleSpinBox2();
 
QToolButton *tool = new QToolButton();
tool->setText("...");
 
QHBoxLayout *layout = new QHBoxLayout(w);
layout->addWidget(editor);
layout->addWidget(tool);
 
return w;

QWdiget *w = new QWidget(parent);
MyDoubleSpinBox2 *editor = new MyDoubleSpinBox2();
 
QToolButton *tool = new QToolButton();
tool->setText("...");
 
QHBoxLayout *layout = new QHBoxLayout(w);
layout->addWidget(editor);
layout->addWidget(tool);

return w;

Dear spirit

In this way, tool button located in the spin not near

[spirit]

can show a screenshot?

[aekilic]

in the attach

[spirit]

this may work

...
QWidget *w = new QWidget(parent);
QSpinBox *sp = new QSpinBox();
QToolButton *tb = new QToolButton();
QHBoxLayout *hbl = new QHBoxLayout(w);	
sp->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
tb->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Preferred);
w->setFocusProxy(sp);
hbl->setMargin(0);
hbl->setSpacing(0);
 
hbl->addWidget(sp);
hbl->addWidget(tb);
 
return w;
...
 
void ItemDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const
{	
	Q_UNUSED(index);
	editor->setGeometry(option.rect);
}

...
QWidget *w = new QWidget(parent);
QSpinBox *sp = new QSpinBox();
QToolButton *tb = new QToolButton();
QHBoxLayout *hbl = new QHBoxLayout(w);	
sp->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
tb->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Preferred);
w->setFocusProxy(sp);
hbl->setMargin(0);
hbl->setSpacing(0);

hbl->addWidget(sp);
hbl->addWidget(tb);

return w;
...

void ItemDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const
{	
	Q_UNUSED(index);
	editor->setGeometry(option.rect);
}

code updated.

[aekilic]

this works great but we have a problem with

void ProformaDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
 {
		QWidget *w = static_cast<MyDoubleSpinBox2*>(editor);
 
		MyDoubleSpinBox2 *spinBox = static_cast<MyDoubleSpinBox2*>(w);
		spinBox->setValue(turkish.toDouble(index.model()->data(index, Qt::EditRole).toString().remove(totalParaBirimi, Qt::CaseInsensitive)));
		spinBox->selectAll();
}

void ProformaDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
 {
		QWidget *w = static_cast<MyDoubleSpinBox2*>(editor);

		MyDoubleSpinBox2 *spinBox = static_cast<MyDoubleSpinBox2*>(w);
		spinBox->setValue(turkish.toDouble(index.model()->data(index, Qt::EditRole).toString().remove(totalParaBirimi, Qt::CaseInsensitive)));
		spinBox->selectAll();
}

Can we do it like this?

[spirit]

no, you can't do this. create your own widget which will return data.

[aekilic]

himmmm

how can I do it then?

[spirit]

the simpliest way

class MyComplexEditor: public QWidget
{
	Q_OBJECT
 
public:
	MyComplexEditor(QWidget *parent = 0) : QWidget(parent)
	{
		m_spinBox = new QSpinBox();
		m_toolButton = new QToolButton();
		QHBoxLayout *hbl = new QHBoxLayout(this);
		m_spinBox->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
		m_toolButton->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Preferred);
		setFocusProxy(m_spinBox);
		hbl->setMargin(0);
		hbl->setSpacing(0);
 
		hbl->addWidget(m_spinBox);
		hbl->addWidget(m_toolButton);
	}
 
	QSpinBox *spinBox() const { return m_spinBox; }
	QToolButton *toolButton() const { return m_toolButton; }
 
private:
	QSpinBox *m_spinBox;
	QToolButton *m_toolButton;
};
 
...
void MyDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	return new MyComplexEditor(parent);
}
 
void MyDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
	MyComplexEditor *mce = qobject_cast<MyComplexEditor *>(editor);
	if (!mce)
		return;
	mce->spinBox()->setValue(turkish.toDouble(index.model()->data(index, Qt::EditRole).toString().remove(totalParaBirimi, Qt::CaseInsensitive)));
	mce->spinBox()->selectAll();
}
}

class MyComplexEditor: public QWidget
{
	Q_OBJECT

public:
	MyComplexEditor(QWidget *parent = 0) : QWidget(parent)
	{
		m_spinBox = new QSpinBox();
		m_toolButton = new QToolButton();
		QHBoxLayout *hbl = new QHBoxLayout(this);
		m_spinBox->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
		m_toolButton->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Preferred);
		setFocusProxy(m_spinBox);
		hbl->setMargin(0);
		hbl->setSpacing(0);

		hbl->addWidget(m_spinBox);
		hbl->addWidget(m_toolButton);
	}

	QSpinBox *spinBox() const { return m_spinBox; }
	QToolButton *toolButton() const { return m_toolButton; }

private:
	QSpinBox *m_spinBox;
	QToolButton *m_toolButton;
};

...
void MyDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	return new MyComplexEditor(parent);
}

void MyDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
	MyComplexEditor *mce = qobject_cast<MyComplexEditor *>(editor);
	if (!mce)
		return;
	mce->spinBox()->setValue(turkish.toDouble(index.model()->data(index, Qt::EditRole).toString().remove(totalParaBirimi, Qt::CaseInsensitive)));
	mce->spinBox()->selectAll();
}
}

nothing complex, right?

[aekilic]

Thank you very much problem solved, but was not complex

[aekilic]

I got one more question for the tool botton

I create a action, and add to toolbotton.

QAction *enDusukAlis = new QAction(QString::fromUtf8("En DüşÃ¼k Alış Fiyatı"), w->toolButton());
connect(enDusukAlis, SIGNAL(activated()), w->toolButton(), SLOT(slotenDusukAlis()));
w->toolButton()->addAction(enDusukAlis);

QAction *enDusukAlis = new QAction(QString::fromUtf8("En DüşÃ¼k Alış Fiyatı"), w->toolButton());
connect(enDusukAlis, SIGNAL(activated()), w->toolButton(), SLOT(slotenDusukAlis()));
w->toolButton()->addAction(enDusukAlis);

To copy to clipboard, switch view to plain text mode 

this slotenDusukAlis has to find something and put a number in a spin. But I was not able to work signal and slot can anybody help?

[spirit]

looks strange

connect(enDusukAlis, SIGNAL(activated()), w->toolButton(), SLOT(slotenDusukAlis()));

connect(enDusukAlis, SIGNAL(activated()), w->toolButton(), SLOT(slotenDusukAlis()));

To copy to clipboard, switch view to plain text mode 

QToolButton has not such slot slotenDusukAlis.
