HeaderView BackgroundColor

[dragon]

Yes the application change a little bit with -style plastque.

Hmm... a little bit? BTW. What does your "MainWindow" class inherit from? If not from QAbstractItemView or one of its subclasses then that's why your header doesn't change colour

[caduel]

try passing a QBrush instead of a QColor?
(and use Qt::BackgroundRole, Qt::BackgroudColorRole is obsolete)

HTH

My "MainWindow" class inherit from QMainWindow see code snippet.

#include <QtOpenGL>

  :QMainWindow(parent)

	setupUi(this);
 
	setWindowIcon(QIcon(":/images/triple20.png"));
	connect(actionInfo, SIGNAL(triggerred()), this, SLOT(info()));
	connect(actionTriple_S, SIGNAL(triggered()), this, SLOT(triple()));
	connect(actionAfsluiten, SIGNAL(triggered()), this, SLOT(exit()));
	connect(pbVerzend, SIGNAL(clicked()), this, SLOT(verzend()));
	connect(pbVerbind, SIGNAL(clicked()), this, SLOT(verbind()));
 
    model = new CustomSqlModel(this);
    model->setTable("planning");
    model->setEditStrategy(QSqlTableModel::OnManualSubmit);
    model->select();

    view->setModel(model);
 
    // etc....

yes, and...
what is your question?

did you try returning a QBrush instead of a QColor?
