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

void ProformaDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const
 {
		    MyComplexEditor *mce = static_cast<MyComplexEditor *>(editor);
		    if (!mce)
		        return;
		    model->setData(index, gosteri.arg(birimFiyat,0,'f',2) + " " + totalParaBirimi, Qt::DisplayRole);
}

void ProformaDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                    const QModelIndex &index) const
 {
		    MyComplexEditor *mce = static_cast<MyComplexEditor *>(editor);
		    if (!mce)
		        return;
		    model->setData(index, gosteri.arg(birimFiyat,0,'f',2) + " " + totalParaBirimi, Qt::DisplayRole);
}

Can any body help?

[spirit]

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);
...

To copy to clipboard, switch view to plain text mode 

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.

[aekilic]

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.

[aekilic]

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.

[spirit]

I have tried this

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.

[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
