Descripción detallada

A collection of QPainter workarounds.

1) Clipping to coordinate system limits (Qt3 only)

On X11 pixel coordinates are stored in shorts. Qt produces overruns when mapping QCOORDS to shorts.

2) Scaling to device metrics

QPainter scales fonts, line and fill patterns to the metrics of the paint device. Other values like the geometries of rects, points remain device independend. To enable a device independent widget implementation, QwtPainter adds scaling of these geometries. (Unfortunately QPainter::scale scales both types of paintings, so the objects of the first type would be scaled twice).

QwtPolygon QwtPainter::clip ( const QwtPolygon & pa ) [static]

Clip a point array.

bool QwtPainter::deviceClipping ( ) [static]

Nota:: A QPicture that is created in SVG mode and saved to the native format, will be misaligned. Also it is not possible to reload and play a SVG document, that was created in SVG mode.
