QItemDelegate Align

[aekilic]

for the code you have sent, problem is I have to create my action in createEditor()

[spirit]

why do you have to do this?

[aekilic]

problem is load create action acording to the values in other columns. for example,

I have 3 rows and 6 columns

for each row I get values of columns 1 and 3 and create an action for the toolbar in column 6 acording to this. If there is no value either in 1 and 3 there wont be any action

[spirit]

so, I don't see any problem, make like this
h-file

class MyComplexEditor: public QWidget
{
	Q_OBJECT
 
public:
	MyComplexEditor(QWidget *parent = 0) : QWidget(parent)
	{
		m_spinBox = new QSpinBox();
		m_toolButton = new QToolButton();
		m_toolButton->setText("...");
		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; }
 
public slots:
	void updateSpinBoxValue()
	{
		const QAction *action = qobject_cast<QAction *>(sender());
		if (!action)
			return;
 
		m_spinBox->setValue(action->data().toInt());
	}
 
private:
	QSpinBox *m_spinBox;
	QToolButton *m_toolButton;
};

class MyComplexEditor: public QWidget
{
	Q_OBJECT

public:
	MyComplexEditor(QWidget *parent = 0) : QWidget(parent)
	{
		m_spinBox = new QSpinBox();
		m_toolButton = new QToolButton();
		m_toolButton->setText("...");
		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; }

public slots:
	void updateSpinBoxValue()
	{
		const QAction *action = qobject_cast<QAction *>(sender());
		if (!action)
			return;

		m_spinBox->setValue(action->data().toInt());
	}
