QItemDelegate Align

[aekilic]

What I use is,

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

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

To copy to clipboard, switch view to plain text mode 

But the signal doesnt work

[Lykurg]

A QAction has only the signals:
void changed ()
void hovered ()
void toggled ( bool checked )
void triggered ( bool checked = false )
void destroyed ( QObject * obj = 0 )

No activated!

yup, Qt Assistant -- rocks!

[aekilic]

yup, Qt Assistant -- rocks!

yes, it really rocks!

For the setData how can I use it then?

.....	
QAction *enDusukSatis = new QAction(QString::fromUtf8("En DüşÃ¼k Satış Fiyatı"), w->toolButton());
connect(enDusukSatis, SIGNAL(triggered()), this, SLOT(test()));
w->toolButton()->addAction(enDusukSatis);
.....
void ProformaDelegate::test()
{
	QMessageBox::warning(0, QString::fromUtf8("HATA"),
	QString::fromUtf8("İşlemde bir hata oluştu \nLütfen tekrar deneyiniz \nveya \nSistem uzmanına başvurunuz"));
 
}

.....	
QAction *enDusukSatis = new QAction(QString::fromUtf8("En DüşÃ¼k Satış Fiyatı"), w->toolButton());
connect(enDusukSatis, SIGNAL(triggered()), this, SLOT(test()));
w->toolButton()->addAction(enDusukSatis);

But the signal doent work...

[spirit]

everything should work, press and hold a tool button, a popup menu should appear with your action. if you want slot is being called immediately then

connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

To copy to clipboard, switch view to plain text mode 

[aekilic]

Dear Spirit

connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

To copy to clipboard, switch view to plain text mode 

also doesnt work

[Lykurg]

Then show us your (whole) code. Maybe Q_OBJECT forgotten? Do you get a warning?

[spirit]

what does this operation show in console?

qDebug() << connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

qDebug() << connect(w->toolButton(), SIGNAL(clicked()), this, SLOT(test()));

To copy to clipboard, switch view to plain text mode 

did you add Q_OBJECT macro in your class declaration.
PS. I've just tested both of these approaches and they work fine for me.

Dear Spirit

Thank you very much for all your help, not I have work out everything but only problem I have is

I get the data loaded on the actiong like this,

QAction *action = qobject_cast<QAction *>(sender());
    if (action)
    {
	birimFiyat = action->data().toDouble();
    }

QAction *action = qobject_cast<QAction *>(sender());
    if (action)
    {
	birimFiyat = action->data().toDouble();
    }

To copy to clipboard, switch view to plain text mode 

But I need the double to be in

Can any body help?

I don't understand why do you need that action?
you need to get data prom spinbox by pressing tool button, right?
if yes, then I don't see any sense of using action, just process clicked signal of tool button and then in a slot do next

...
emit commitData(widget);
emit closeEditor(widget, QAbstractItemDelegate::SubmitModelCache);
...

...
emit commitData(widget);
emit closeEditor(widget, QAbstractItemDelegate::SubmitModelCache);
...

where widget it's you complex widget.
so, try this

QWidget *ItemDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    Q_UNUSED(option);
    Q_UNUSED(index);
 
    MyComplexEditor *mce = new MyComplexEditor(parent);
    connect(mce->toolButton(), SIGNAL(clicked()), SLOT(test()));
 
    return mce;
}
 
void ItemDelegate::test()
{
    QMessageBox::information(0, tr("information"), tr("test"));
    QToolButton *toolButton = qobject_cast<QToolButton *>(sender());
    if (!toolButton)
        return;
    MyComplexEditor *mce = qobject_cast<MyComplexEditor *>(toolButton->parentWidget());
    if (!mce)
        return;    
    emit commitData(mce);
    emit closeEditor(mse, QAbstractItemDelegate::SubmitModelCache);
}

QWidget *ItemDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    Q_UNUSED(option);
    Q_UNUSED(index);
 
    MyComplexEditor *mce = new MyComplexEditor(parent);
    connect(mce->toolButton(), SIGNAL(clicked()), SLOT(test()));
 
    return mce;
}
 
void ItemDelegate::test()
{
    QMessageBox::information(0, tr("information"), tr("test"));
    QToolButton *toolButton = qobject_cast<QToolButton *>(sender());
    if (!toolButton)
        return;
    MyComplexEditor *mce = qobject_cast<MyComplexEditor *>(toolButton->parentWidget());
    if (!mce)
        return;    
    emit commitData(mce);
    emit closeEditor(mse, QAbstractItemDelegate::SubmitModelCache);
}

after that setModelData will be called and data will be set in model.
btw, you don't need to chage this method setModelData leave it as is.
hope this helps.

No I need the action because I bring the actions from sql amd evey action has a different number which I set them by setData.

I need to set those numbers to spin when I select from tool.

[spirit]

sigh, then you need:
1. add actions in complex editor
2. create needed connection
3. process triggered signals
4. set values in spinbox.

then you need modify you delegate in this way:
1. remove connect(mce->toolButton(), SIGNAL(clicked()), SLOT(test()));
2. remove test slot.
3. leave setModelData as is.

I have tried this

connect(recentFileActs[i], SIGNAL(triggered()), this, SLOT(w->spinBox()->setValue(fiyat_tipleri.value(4).toDouble())));

connect(recentFileActs[i], SIGNAL(triggered()), this, SLOT(w->spinBox()->setValue(fiyat_tipleri.value(4).toDouble())));

To copy to clipboard, switch view to plain text mode 

But it didnt work

[faldzip]

you can't connect signal to a slot when signal has less number of parameters than slot wants to get. Because from where that slot should take those missing arguments?
and SLOT(asd()) uses asd() as "asd()" character string (or even something like "2asd()" or more complicated :]), not a function call.

connect(recentFileActs[i], SIGNAL(triggered()), this, SLOT(w->spinBox()->setValue(fiyat_tipleri.value(4).toDouble())));

select one of action and close editor (click on another item), data in cell will be stored to model.
