示例1: GpiMove
QRegion::QRegion( const QPointArray &a, bool winding )
{
data = new QRegionData;
Q_CHECK_PTR( data );
data->hgt = 0;
data->is_null = FALSE;
QRect r = a.boundingRect();
if ( a.isEmpty() || r.isEmpty() ) {
data->rgn = 0;
} else {
HPS hps = qt_display_ps();
POINTL *pts = new POINTL[ a.size() ];
for ( uint i = 0; i < a.size(); ++ i ) {
pts[i].x = a[i].x();
pts[i].y = - (a[i].y() + 1);
}
// GpiCreatePolygonRegion() is bogus and always starts a poligon from
// the current position. Make the last point the current one and reduce
// the number of points by one.
GpiMove( hps, &pts[ a.size() - 1 ] );
POLYGON poly = { a.size() - 1, pts };
ULONG opts = winding ? POLYGON_WINDING : POLYGON_ALTERNATE;
data->rgn = GpiCreatePolygonRegion( hps, 1, &poly, opts );
delete[] pts;
}
