[grsandeep85]

Hi All,

I have the treeeView which has 4 columns now the header label has set according to the string length but now i need to increase the size of the header label. How to do this and here is my code snippet

model = new QStandardItemModel( this );
    model->setHorizontalHeaderLabels( QStringList() << "TOOL NUMBER" << "DIAMETER" << "LENGTH" << "UNITS" );
    tooltreeView->setModel( model );

model = new QStandardItemModel( this );
    model->setHorizontalHeaderLabels( QStringList() << "TOOL NUMBER" << "DIAMETER" << "LENGTH" << "UNITS" );
    tooltreeView->setModel( model );
