QTableView column header is invisible

[grsandeep85]

Hi All,

I have made a QTableView with 200 rows and 4 columns.. but the column header are invisible and here is my code snippet.

toolform.cpp

ToolForm::ToolForm(QDialog *parent, Qt::WindowFlags f)
          : QDialog( parent, f)
{
        setupUi(this);
        setupModel();
        setupViews();
        init();
}
 
ToolForm::~ToolForm()
{
}
 
void ToolForm::init()
{
 
}
void ToolForm::setupModel()
{
     model = new QStandardItemModel(200, 4, this);
     model->setHeaderData(0, Qt::Horizontal, tr("NUMBER"));
     model->setHeaderData(1, Qt::Horizontal, tr("DIAMETER"));
     model->setHeaderData(2, Qt::Horizontal, tr("LENGTH"));
     model->setHeaderData(3, Qt::Horizontal, tr("UNITS"));
}
 
void ToolForm::setupViews()
{
      QTableView *tooltableView = new QTableView;
      tooltableView->setModel(model);
      QItemSelectionModel *selectionModel = new QItemSelectionModel(model);
      tooltableView->setSelectionModel(selectionModel);
}

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

ToolForm::~ToolForm()
{
}

void ToolForm::init()
{

}
void ToolForm::setupModel()
{
     model = new QStandardItemModel(200, 4, this);
     model->setHeaderData(0, Qt::Horizontal, tr("NUMBER"));
     model->setHeaderData(1, Qt::Horizontal, tr("DIAMETER"));
     model->setHeaderData(2, Qt::Horizontal, tr("LENGTH"));
     model->setHeaderData(3, Qt::Horizontal, tr("UNITS"));
}

void ToolForm::setupViews()
{
      QTableView *tooltableView = new QTableView;
      tooltableView->setModel(model);
      QItemSelectionModel *selectionModel = new QItemSelectionModel(model);
      tooltableView->setSelectionModel(selectionModel);
}

How to resolve this issue.

try this:

void ToolForm::setupViews()
{
      QTableView *tooltableView = new QTableView;
      tooltableView->setModel(model);
      QItemSelectionModel *selectionModel = new QItemSelectionModel(model);
      tooltableView->setSelectionModel(selectionModel);
      toolrableView->show();   
}

void ToolForm::setupViews()
{
      QTableView *tooltableView = new QTableView;
      tooltableView->setModel(model);
      QItemSelectionModel *selectionModel = new QItemSelectionModel(model);
      tooltableView->setSelectionModel(selectionModel);
      toolrableView->show();   
}
