QComboBox and HeaderItem

? Offline

Dear all, I have a QComboBox with a QStandardItemModel, which contains a single item named "One".
I want the QComboBox to have an header (I'm not sure this is the correct technical term ...) which will always be the same.

[1] To be more precise, running the code below leads to the following output:
"One" (as the header) + "One" (with a checkbox).

[2] What I'm looking for is as follows:
"Header" (as the header) + "One" (with a checkbox).

I tried the function "model.setHorizontalHeaderItem()" but it leads to the same as [1] above.
Please, help me.

@#include <QApplication>
#include <QComboBox>
#include <QStandardItemModel>

int main( int argc, char **argv )
{
QApplication app( argc, argv );

QComboBox* comboBox = new QComboBox();

QStandardItemModel model( 1, 1 );
QStandardItem *item = new QStandardItem( QString("One") );

item->setFlags( Qt::ItemIsUserCheckable | Qt::ItemIsEnabled );
item->setData ( Qt::Unchecked, Qt::CheckStateRole );

model.setItem(0, 0, item);

model.setHorizontalHeaderItem( 0, new QStandardItem( "Header" ) );

comboBox->setModel( &model );
comboBox->show();

return app.exec();
}@

See QComboBox::setView , QComboBox uses QListWidget as view by default and there's no header. Set QTreeWidget as QComboBox view and there you can set header.
