How to read and write data into the QTableView

[grsandeep85]

Hi All,

I have made a QTableView which has 200 rows and 4 columns, when the user press the enter Key it opens a new QDialog which has 4 QlineEdits and these QlineEdits values has to be displayed in QTableView. here is the code snippet for QDialog

tooladddialog.cpp

QString ToolAddDialog::toolgetValues()
{
    QString line;
 
    toolnolineEdit->selectAll();
    line.append( toolnolineEdit->text() );
    line.append( " " );
 
    diameterlineEdit->selectAll();
    line.append( diameterlineEdit->text() );
    line.append( " " );
 
    lengthlineEdit->selectAll();
    line.append( lengthlineEdit->text() );
    line.append( " " );
 
    unitslineEdit->selectAll();
    line.append( unitslineEdit->text() );
    return line;
}

QString ToolAddDialog::toolgetValues()
{
    QString line;

    toolnolineEdit->selectAll();
    line.append( toolnolineEdit->text() );
    line.append( " " );
   
    diameterlineEdit->selectAll();
    line.append( diameterlineEdit->text() );
    line.append( " " );
  
    lengthlineEdit->selectAll();
    line.append( lengthlineEdit->text() );
    line.append( " " );

    unitslineEdit->selectAll();
    line.append( unitslineEdit->text() );
    return line;
}

To copy to clipboard, switch view to plain text mode 

tooform.cpp

void ToolForm::keyPressEvent( QKeyEvent *event )
{
    qDebug( "Key Press Event" );
    switch ( event->key() )
    {
       case Qt::Key_Return: //Mapped with Enter Key
	 add_tool();
 
	 break;
 
        case Qt::Key_Escape:  //Mapped with Cancel key
         close();
         break;
 
    default:
         QWidget::keyPressEvent(event);
    }
}
 
void ToolForm::add_tool()
{
    ToolAddDialog tooladddialog;
 
    if( tooladddialog.exec())
    {
        QString str = tooladddialog.toolgetValues();
        QStringList fields = str.split(" ");
 
        if (!tooltableView)
        return;
        // now values should be added to the QTableView
   }
}

void ToolForm::keyPressEvent( QKeyEvent *event )
{
    qDebug( "Key Press Event" );
    switch ( event->key() )
    {
       case Qt::Key_Return: //Mapped with Enter Key
	 add_tool();
	 
	 break;

        case Qt::Key_Escape:  //Mapped with Cancel key
         close();
         break;

    default:
         QWidget::keyPressEvent(event);
    }
}

void ToolForm::add_tool()
{
    ToolAddDialog tooladddialog;

    if( tooladddialog.exec())
    {
        QString str = tooladddialog.toolgetValues();
        QStringList fields = str.split(" ");

        if (!tooltableView)
        return;
        // now values should be added to the QTableView
   }
}

How to resolve this issue. if any snippet would be advantage.

use QAbstractItemModel::setData for setting data into model.
PS. read about Model/View programming also.
