[SOLVED] Polygon with holes fading
-
I have managed to get a polygon with holes appearing. However the holes get darker and darker for some reason?
Here is an example...
!http://www.streettrack.co.uk/polygonhole.jpg(Example of polygon hold)!
Here is the code:
@
QPainterPath path;
path.addPolygon(poly); // Outer region.
if (v_polyinner.size() > 0)
{
QPainterPath inner;
for (int iPoly = 0; iPoly < v_polyinner.size(); iPoly++)
{
inner.addPolygon(v_polyinner[iPoly]);
}
path = path.subtracted(inner);
}stringstream sscolour;
sscolour << "#" << polyi->getColour();
QColor colour(QString::fromStdString(sscolour.str()));
colour.setAlpha(127);
QBrush brush(colour);
painter.setBrush(brush);
if (this->sSelectedItemGUID == polyi->getFeatureGUID()) painter.setPen(penHighlight);
painter.fillPath(path, brush);
@It's seems as though as each polygon is added is goes darker.
