I am drawing points on the screen, and what I am noticing is that
sometimes the points are displayed and sometimes they aren't.
Here is the call stack of an attempt to display a point:
QPainterPath::isEmpty(void) Line: 336
QRasterPaintEngine::drawPath(QPainterPath& path = {...}) Line:
1712
QRasterPaintEngine::drawPoints(QPointF* points = 0x20ba2e34, int
pointCount = 1) Line: 3148
QPaintEngine::drawPoints(QPoint* points = 0x20ba36d0, int
pointCount = 1) Line: 426,
QPainter::drawPoints(QPoint* points = 0x20ba36d0, int pointCount =
1) Line: 3103
QPainter::drawPoint(int x = 190, int y = 133) Line: 593
I believe the issue is that when drawPath is called on
QRasterPaintEngine, the isEmpty call on line 1712 is returning true.
For the points that are being displayed, the isEmpty call is returning
false.
I am using Qt 4.4.0 on Windows Mobile 5.0.
Best regards,
George
