QItemDelegate Align

[aekilic]

Dear All

We have a problem,

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

MyDoubleSpinBox2 *editor = new MyDoubleSpinBox2(parent);

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

		return editor;

When we do this we get the tool button on left, how we could get the button on right?

[spirit]

try to use QWidget::setGeometry or QWidget::move. but anyway when editor is being resized you need to move your tool button to new position. so, you can process QResizeEvent of your editor and update tool button position. another way it's to put your editor and tool button in layout.

[wysota]

Move it there using QWidget API.

[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

[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.

Dear All

What I need to do is,

I have QAction's on the QToolMenu,

Like
Best Price '10'
Low Price '8'

What I need to do is, after user select Best Price '10' I need to put 10 to the spin...

Am I able to explain?

[Lykurg]

a) use QRegExp to extract the number of the displayed text
or better
b) use QAction::setData() to store your number while generating the QActions

use the QToolButton::triggered ( QAction * action ) signal.
