I did that exactly but unfortunately it didn't work :(
May you please tell me what's wrong?!
I'm still get "5.25446e+06" for "5254458.963"
I call the following:
---
ui->tableView->setModel(_tableModel);
ui->tableView->resizeColumnsToContents();
EcsLongDigitDelegate *delegate = new EcsLongDigitDelegate;
ui->tableView->setItemDelegateForColumn(2, delegate);
---
Database table (SQLite):
---
CREATE TABLE "names" ("id" INTEGER PRIMARY KEY NOT NULL
,"nam_full_name" TEXT,"nam_id" DOUBLE DEFAULT (null) );
---
Delegate class:
---
#include "ecslongdigitdelegate.h"
EcsLongDigitDelegate::EcsLongDigitDelegate(QObject *parent) :
QStyledItemDelegate(parent)
{
}
QWidget *EcsLongDigitDelegate::createEditor(QWidget *parent, const
QStyleOptionViewItem &option, const QModelIndex &index) const
{
QDoubleSpinBox *editor = new QDoubleSpinBox(parent);
editor->setFrame(false);
editor->setMinimum(0);
editor->setDecimals(3);
editor->setMaximum(999999999999);
return editor;
}
void EcsLongDigitDelegate::setEditorData(QWidget *editor, const
QModelIndex &index) const
{
double value = index.model()->data(index, Qt::DisplayRole).toDouble();
QDoubleSpinBox *spinBox = static_cast<QDoubleSpinBox*>(editor);
spinBox->setValue(value);
}
void EcsLongDigitDelegate::setModelData(QWidget *editor,
QAbstractItemModel *model, const QModelIndex &index) const
{
QDoubleSpinBox *spinBox = static_cast<QDoubleSpinBox*>(editor);
spinBox->interpretText();
double value = spinBox->value();
model->setData(index, value, Qt::DisplayRole);
}
void EcsLongDigitDelegate::updateEditorGeometry(QWidget *editor, const
QStyleOptionViewItem &option, const QModelIndex &index) const
{
editor->setGeometry(option.rect);
}
