How to add data into the QTableWidget

[grsandeep85]

Hi All,
I have a QTableWidget which has 200 rows and 4 columns. The user will input the data from 4 QlineEdits in a different dialog. These 4 QlineEdit Values has to be displayed in the QTableWidget. How to resolve this issue. any snippts will be greatful.

the simplest way. it is to pass pointer to QTableWidget into your dialog.

Dialog::Dialog(QTableWidget *table, QWidget *parent)
   : Dialog(parent), m_table(table)
{
....
}
 
void Dialog::saveDataIntoTable()
{
   if (!m_table)
      return;
 
   const int currentRow = m_table->rowCount();  
   m_table->setRowCount(currentRow + 1);
 
   m_table->setItem(currentRow, 0, new QTableWidgetItem(m_lineEdit1->text()));
   m_table->setItem(currentRow, 1, new QTableWidgetItem(m_lineEdit2->text()));
   ...
}

Dialog::Dialog(QTableWidget *table, QWidget *parent)
   : Dialog(parent), m_table(table)
{
....
}

void Dialog::saveDataIntoTable()
{
   if (!m_table)
      return;

   const int currentRow = m_table->rowCount();  
   m_table->setRowCount(currentRow + 1);

   m_table->setItem(currentRow, 0, new QTableWidgetItem(m_lineEdit1->text()));
   m_table->setItem(currentRow, 1, new QTableWidgetItem(m_lineEdit2->text()));
   ...
}

To copy to clipboard, switch view to plain text mode

another way is to create getters in your dialog and use them to get values after dialog.exec() returns.

Thanks for the reply my intension is to make application similar to addressbook example in Qt but instead of Listview i need to use TableWidget..

And here is my code snippet

ToolForm::ToolForm( QDialog *parent, Qt::WindowFlags f)
          : QDialog( parent, f), 
{
        setupViews();
        setupUi(this);	
}
 
ToolForm::~ToolForm()
{
}
 
void ToolForm::setupViews()
{
      QTableWidget *tooltableWidget = new QTableWidget(200, 4, this);
      tooltableWidget->setHorizontalHeaderLabels(QStringList() << tr("TOOL NUMBER")
                                                               << tr("DIAMETER")
                                                               << tr("LENGTH")
                                                               << tr("UNITS"));
      tooltableWidget->verticalHeader()->setVisible(false);
      tooltableWidget->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      tooltableWidget->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      tooltableWidget->setShowGrid(false);
      tooltableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
      tooltableWidget->setGeometry(QRect(0, 100, 781, 281));
      tooltableWidget->horizontalHeader()->resizeSection(1, 250);
      tooltableWidget->horizontalHeader()->resizeSection(2, 250);
      tooltableWidget->horizontalHeader()->resizeSection(3, 180);
  }
 
void ToolForm::add_tool()
{
    ToolAddDialog tooladddialog;
 
    if( tooladddialog.exec())
    {
 
        QTableWidget *tooltableWidget = new QTableWidget;
        QString str = tooladddialog.toolgetValues();
        QStringList fields = str.split(" ");
        //now i need to display the values from tooladddialog. to TableWidget
    }
}

ToolForm::ToolForm( QDialog *parent, Qt::WindowFlags f)
          : QDialog( parent, f), 
{
        setupViews();
        setupUi(this);	
}

ToolForm::~ToolForm()
{
}

void ToolForm::setupViews()
{
      QTableWidget *tooltableWidget = new QTableWidget(200, 4, this);
      tooltableWidget->setHorizontalHeaderLabels(QStringList() << tr("TOOL NUMBER")
                                                               << tr("DIAMETER")
                                                               << tr("LENGTH")
                                                               << tr("UNITS"));
      tooltableWidget->verticalHeader()->setVisible(false);
      tooltableWidget->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      tooltableWidget->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
      tooltableWidget->setShowGrid(false);
      tooltableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
      tooltableWidget->setGeometry(QRect(0, 100, 781, 281));
      tooltableWidget->horizontalHeader()->resizeSection(1, 250);
      tooltableWidget->horizontalHeader()->resizeSection(2, 250);
      tooltableWidget->horizontalHeader()->resizeSection(3, 180);
  }
 
void ToolForm::add_tool()
{
    ToolAddDialog tooladddialog;
    
    if( tooladddialog.exec())
    {

        QTableWidget *tooltableWidget = new QTableWidget;
        QString str = tooladddialog.toolgetValues();
        QStringList fields = str.split(" ");
        //now i need to display the values from tooladddialog. to TableWidget
    }
}

Then you probably have an error in your source code. Show us your relevant code, then we can help.

Could some one tell me how to do the same using JavaScript? Really appreciated.
