[tkms]

I want to change the backgroundcolor, that some files in treeview.

but, I don't know how to change.

QVariant MyTreeModel::data(const QModelIndex &index, int role) const
{
....
if (role == Qt::BackgroundRole)
return QColor(lightGray);
....
}

I want to add a color to the parent of the file which I chose. how should I do it?

use this method


bool QAbstractItemModel::setData ( const QModelIndex & index, const QVariant & value, int role = Qt::EditRole )

i.e. in you case


...
QVariant v = QColor(Qt::red);
myModel->setData(index, v, Qt::BackgroundRole);
...
