[SOLVED] Get the value of Qdoublespixbox implemented in delegate

[advseo32]

Hello,

i have a problem of getting a value of Qdoublespixbox imlemented in delegate

@QWidget *customTableSellDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
if(!index.isValid())
return QStyledItemDelegate::createEditor(parent,option,index);
QDoubleSpinBox *doubleSpinBoxEditor = new QDoubleSpinBox(parent);
doubleSpinBoxEditor->setRange(-999999999999999.99,999999999999999999.99);
doubleSpinBoxEditor->setSuffix(" D.A");
doubleSpinBoxEditor->setDecimals(2);
doubleSpinBoxEditor->setButtonSymbols(QDoubleSpinBox::PlusMinus);
doubleSpinBoxEditor->setFrame(false);
return doubleSpinBoxEditor;

}@

and i have added the delegate to my qtablwidget

@ m_tableDelegate = new customTableSellDelegate(this);
ui->tableWidget->setItemDelegate(m_tableDelegate);@

after that when the user make some change in qtablewidget

i tried to get a value from qtablewidget

@double qty = ui->tableWidget->item(row,2)->text().toDouble(); @

but it return 0 alway, even thought i write 25 , so what's the problem

Hi,

What does ui->tableWidget->item(row,2)->text() return ?

[advseo32]

i have writed 25 in qtablewidget but

but ui->tableWidget->item(row,2)->text()

returns "Ƀ砀Ƀሀ䑫\002簓Ʉ\000㬷\027Ԁȟ婟䭎儶敒瑣ㅆ椱瑮牥敳瑣摥剅卋_㖊\002ꬁɃ똀" ( using debugger )

That doesn't look like a number.

Did you completely implement the delegate ?

[advseo32]

Yes this is my custom delegate

@#include "customtableselldelegate.h"
#include <QDoubleSpinBox>
#include <QComboBox>
#include <QDebug>
customTableSellDelegate::customTableSellDelegate(QObject *parent) :
QStyledItemDelegate(parent)

}

QWidget *customTableSellDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
if(!index.isValid())
return QStyledItemDelegate::createEditor(parent,option,index);

int col= index.column();

if(col == 1)
{
    QComboBox *comboboxEditor = new QComboBox(parent);
    comboboxEditor->addItem("Item1");
    comboboxEditor->addItem("Item2");
    comboboxEditor->addItem("Item3");
    comboboxEditor->addItem("Item4");
    comboboxEditor->addItem("Item5");
    comboboxEditor->addItem("Item6");


    return comboboxEditor;

}
// col3
else if(col ==2 || col ==3 || col ==4 || col == 5 || col == 6 || col == 7)
{
    QDoubleSpinBox *doubleSpinBoxEditor = new QDoubleSpinBox(parent);
    doubleSpinBoxEditor->setRange(-999999999999999.99,999999999999999999.99);
    doubleSpinBoxEditor->setSuffix(" D.A");
    doubleSpinBoxEditor->setDecimals(2);
    doubleSpinBoxEditor->setButtonSymbols(QDoubleSpinBox::PlusMinus);
    doubleSpinBoxEditor->setFrame(false);
    return doubleSpinBoxEditor;


}else{
    return QStyledItemDelegate::createEditor(parent,option,index);
}

}

void customTableSellDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
if(!index.isValid())
return QStyledItemDelegate::setEditorData(editor,index);

int col= index.column();

if(col == 1)
{
    QString data = index.model()->data(index,Qt::DisplayRole).toString();
    QComboBox *comboboxEditor = qobject_cast<QComboBox*>(editor);

    comboboxEditor->setCurrentText(data);
}

else if(col ==2 || col ==3 || col ==4 || col == 5 || col == 6 || col == 7)
{

    doubleSpinBoxEditor->setButtonSymbols(QDoubleSpinBox::PlusMinus);
    doubleSpinBoxEditor->setFrame(false);
    doubleSpinBoxEditor->setValue(data);

}else{
    QStyledItemDelegate::setEditorData(editor,index);
}

}

void customTableSellDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const
{
if(!index.isValid())
return QStyledItemDelegate::setModelData(editor,model,index);

int col= index.column();

if(col == 1)
{
    QComboBox *comboboxEditor = qobject_cast<QComboBox*>(editor);

    model->setData(index,comboboxEditor->currentText(),Qt::EditRole);

    emit unlockRow(index);


}
// col3
else if(col ==2 || col ==3 || col ==4 || col == 6 || col == 7)

    {
        emit qtyPriceDataChanged(index);
    }
}else{

}

void customTableSellDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const

Why are you setting the double spin box properties in each function ? You should only do that when creating the editor.

Why ?
@model->setData(index,doubleSpinBoxEditor->textFromValue(doubleSpinBoxEditor->value()),Qt::EditRole)@

rather :

@model->setData(index,doubleSpinBoxEditor->value(),Qt::EditRole)@

As a side note, in setModelData, you don't handle column 5.

Have a look at the Spin Box delegate example
