Show integer value in qtable widget

[artwaw]

@VRonin said in Show integer value in qtable widget:

QString::number and QString::toInt should never be used for things that are shown on the ui.

I apologize for hijacking the thread but what if you have just plain integers and you are sure that values are locale independent?

[VRonin]

While we think arab numbers are universal, they are not. Chinese locales, for example, have special unicode chars for numbers (0 = 零, 1 = 一) . Even arabic has different chars for arab numbers

@VRonin Thank you!

@Taz742 thank you.. it works..

Yes it works. But review the comments and then make a decision.
I think it's better if you use another method what @VRonin said.

auto widItem = new QTableWidgetItem;
widItem->setData(Qt::EditRole,rgnt.R_id);
ui->tableWidget_3->setItem(0,1,widItem);

@VRonin
Why does not it take Qt::Checked or Qt::Unchecked?

You need to adjust the flag too for that role to matter widItem->setFlags(widItem->flags() | Qt::ItemIsUserCheckable);

@VRonin Can not I give it my function?

QTableWidgetItem *dlgGroups::GetNewItem(const QVariant value){
    auto c_item = new QTableWidgetItem;
         c_item->setData(Qt::UserRole, value);
    return (QTableWidgetItem*) c_item;
}

Contact *cont = globalall->GetConact(CUID);

m_table->insertRow(0);
m_table->setItem(0, 0, GetNewItem(InsertQry.lastInsertId().toString()));
m_table->setItem(0, 1, GetNewItem(cont->UID));
m_table->setItem(0, 2, GetNewItem(Qt::Unchecked)); // ?
m_table->setItem(0, 3, GetNewItem(cont->Name + " " + cont->FamilyName));
m_table->setItem(0, 4, GetNewItem(cont->Mobile));
m_table->setItem(0, 5, GetNewItem(cont->Type ? cont->Identification : cont->PersonID));

@Taz742

1. you still did not set the flag
2. you are saving everything in Qt::UserRole which is never used by Qt's standard views

QTableWidgetItem *dlgGroups::GetNewItem(const QVariant& value, int role = Qt::EditRole){
    auto c_item = new QTableWidgetItem;
    c_item->setData(role , value);
    if(role==Qt::CheckStateRole)
        c_item->setFlags(c_item->flags() | Qt::ItemIsUserCheckable);
    return c_item;
}

then you can use m_table->setItem(0, 2, GetNewItem(Qt::Unchecked,Qt::CheckStateRole));
