QPainterPath set operations deprecated in Qt 4.8
-
From this blog post about Qt 4.8
http://labs.qt.nokia.com/2011/05/12/qt-modules-maturity-level-the-list/
It says that QPainterPath set operations are deprecated from now on. So what does this say about set operations on QPolygonF and other similar classes. I read their code and found that they used to use QPainterPath for implementing these methods.
-
If there is no statement about deprecating those, they will likely be changed into not using the painter path anymore, but don't take my word for it.
-
The set operations for QPolygonF and other similar classes are all deprecated too.
-
That's a clear answer :)

Thanks @sigrid.

@Franzk I was hoping the same.

Hrmm, I just noticed these were being deprecated. I'm going to really miss QPainterPath::setElementPositionAt. I use it to warp text to a curve. For example:
@
QString text = "Sample string";QFont font;
QFontMetricsF fontMetric(font);qreal textWidth = fontMetric.boundingRect(text).width();
qreal circumfrance = 2PItextRadius;
qreal textSweepAngle = (360.0 * textWidth) / circumfrance;QPainterPath path;
path.addText(QPoint(0,0), scaledFont, text );//warp points around a circle
for (int i=0; i<path.elementCount(); i++)
{
const QPainterPath::Element &e = path.elementAt(i);
qreal theta = MathTools::correctAngle(-90 + textSweepAnglee.x / textWidth;
qreal r = textRadius - e.y;
path.setElementPositionAt(i, rcos(theta), r*sin(theta));
}
@If QPainterPath::setelementPositionAt is going to be removed, won't it be impossible to warp text around a curve in Qt5?
