QTableView和空頭和列

Question

我有一個QTableView對象，當我從showIndicators切換到showIndiValues時，我得到這個醜陋的空頭標題行。哪裏有問題？

void DBTableView::showIndicators() 
{ 
    enum { 
     indicators_Id = 0, 
     indicators_Name = 1, 
     indicators_CondName = 2, 
     indicators_MeasureName = 3, 
     indicators_Description = 4, 
     indicators_Responsible = 5 
    }; 

    QSqlQueryModel *model = new QSqlQueryModel; 
    model->setQuery("SELECT * FROM viewIndicators"); 

    model->setHeaderData(indicators_Id, Qt::Horizontal, tr("ID")); 
    model->setHeaderData(indicators_Name, Qt::Horizontal, tr("Name")); 
    model->setHeaderData(indicators_CondName, Qt::Horizontal, tr("Condition Name")); 
    model->setHeaderData(indicators_MeasureName, Qt::Horizontal, tr("Measure")); 
    model->setHeaderData(indicators_Description, Qt::Horizontal, tr("Description")); 
    model->setHeaderData(indicators_Responsible, Qt::Horizontal, tr("Responsible")); 

    /* TableView part */ 
    setModel(model); 
    hideColumn(indicators_Id); 
    QHeaderView *horizontalHeader = this->horizontalHeader(); 
    horizontalHeader->setStretchLastSection(true); 
    QHeaderView *verticalHeader = this->verticalHeader(); 
    verticalHeader->setStretchLastSection(true); 
    setSelectionBehavior(QAbstractItemView::SelectRows); 

    setColumnWidth(indicators_Id, 0); 
    setColumnWidth(indicators_Name, 400); 
    setColumnWidth(indicators_CondName, 120); 
    setColumnWidth(indicators_MeasureName, 120); 
    setColumnWidth(indicators_Description, 400); 

    createIndicatorContextMenu(); 
    show(); 
} 
void DBTableView::showIndiValues() 
{ 
    enum { 
     iv_Id = 0, 
     indicatorId = 1, 
     indicatorName = 2, 
     intervalName = 3, 
     iv_DataValue = 4, 
     iv_DataDate = 5, 
     iv_DataBirth = 6 
    }; 

    QSqlQueryModel *model = new QSqlQueryModel; 
    model->setQuery("SELECT * FROM viewIndiValues"); 

    model->setHeaderData(iv_Id, Qt::Horizontal, tr("ID")); 
    model->setHeaderData(indicatorId, Qt::Horizontal, tr("Indicator ID")); 
    model->setHeaderData(indicatorName, Qt::Horizontal, tr("Indicator name")); 
    model->setHeaderData(intervalName, Qt::Horizontal, tr("Interval name")); 
    model->setHeaderData(iv_DataValue, Qt::Horizontal, tr("Value")); 
    model->setHeaderData(iv_DataDate, Qt::Horizontal, tr("Date")); 
    model->setHeaderData(iv_DataBirth, Qt::Horizontal, tr("Creation date")); 

    setModel(model); 
    hideColumn(iv_Id); 
    hideColumn(indicatorId); 
    QHeaderView *horizontalHeader = this->horizontalHeader(); 
    horizontalHeader->setStretchLastSection(false); 
    QHeaderView *verticalHeader = this->verticalHeader(); 
    verticalHeader->setStretchLastSection(false); 
    setSelectionBehavior(QAbstractItemView::SelectItems); 

    setColumnWidth(indicatorName, 400); 
    setColumnWidth(intervalName, 200); 
    setColumnWidth(iv_DataValue, 200); 
    setColumnWidth(iv_DataDate, 120); 
    setColumnWidth(iv_DataBirth, 120); 

    createIndiValueContextMenu(); 
    show(); 
}

我做了特殊功能QTableView中，從以前的型號清除列。所以問題就消失了。
