QItemDelegate Align

[aekilic]

can we do it with

bool QLayout::setAlignment ( QWidget * w, Qt::Alignment alignment )???

[spirit]

there is not necessary of using this method. all what you need it's to put all widget in right order. you need to use QHBoxLayout.
but in this case your tool button will not be located on your editor, but it will be located on ther right of your spindox.

I was not able to use QHBoxLayout,

When I use

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

MyDoubleSpinBox2 *editor = new MyDoubleSpinBox2(parent);

		QToolButton *tool;
		tool = new QToolButton();
		tool->setText("...");

	    QHBoxLayout layout;
	    layout.addWidget(editor);
	    layout.addWidget(tool);

I could not see tool button

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.

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?
