Message definition (Development/Tutorials/Qt4 Ruby Tutorial/Chapter 09)

The [http://doc.qt.nokia.com/latest/qpainter.html#rotate Qt::Painter::rotate()] function rotates the coordinate system of the [http://doc.qt.nokia.com/latest/qpainter.html Qt::Painter] around the origin. The rotation argument is given in degrees (not given in sixteenths of a degree as above) and clockwise. Here we rotate the coordinate system '''<tt>@currentAngle</tt>''' degrees counter-clockwise.

Funktio Qt::Painter::rotate() pyörittää Qt::Painter-koordinaattijärjestelmää alkupisteen ympäri. Kiertoargumentti annetaan asteina (ei aseteen 16-osina, kuten yllä) ja vastapäivään. Tässä pyöritämme koordinaattijärjestelmää @currentAngle-astetta vastapäivään.
