Zeljko and others, can you explain why the default implementation of Chord works wrong with QT?
There is no widgetset specific implementation.

See a demo project in

Actually the problem is in TQtWidgetSet.AngleChord which only calls QPainter_drawChord.
Maybe it interprets the parameters differently.

For sure. What params are passed to the QPainter_drawChord() ? QPainter_drawChord() draws the chord defined by the given rectangle (x,y,width (x1),height (y2)), startAngle and spanAngle. The chord is filled with the current brush().

The startAngle and spanAngle must be specified in 1/16th of a degree, i.e. a full circle equals 5760 (16 * 360). Positive values for the angles mean counter-clockwise while negative values mean the clockwise direction. Zero degrees is at the 3 o'clock position.

Feel free to fix it
