Hello,
I am trying to customise the drop indicator in QTreeView with no success. I've browsed the web, but found no info.
Can anyone guide me where to start?

Hi
look at QProxyStyle.
Here's an example I've made for the DropIndicator.
class MyProxyStyle : public QProxyStyle
{
public:
void drawPrimitive(PrimitiveElement element, const QStyleOption *option, QPainter *painter, const QWidget *widget) const
{
if(element == QStyle::PE_IndicatorItemViewItemDrop)
{
painter->setRenderHint(QPainter::Antialiasing, true);
QPalette palette;
//QColor(90,108,217)
QColor c(palette.highlightedText().color());
QPen pen(c);
pen.setWidth(2);
c.setAlpha(50);
QBrush brush(c);
painter->setPen(pen);
painter->setBrush(brush);
if(option->rect.height() == 0)
{
painter->drawEllipse(option->rect.topLeft(), 3, 3);
painter->drawLine(QPoint(option->rect.topLeft().x()+3, option->rect.topLeft().y()), option->rect.topRight());
} else {
painter->drawRoundedRect(option->rect, 5, 5);
}
} else {
QProxyStyle::drawPrimitive(element, option, painter, widget);
}
}
};
