I have the trackpad QTouchEvent screen zooming on my mac and no printer support.. :-(
I try from old qt4 sample code and other stuff or demo.
Is this a mac problem?
void BigFox::printPwd() {
#ifndef QT_NO_PRINTER
QPrinter printer(QPrinter::HighResolution);
printer.setOutputFileName("");
QPrintDialog pp(&printer,this );
int resultofexec = pp.exec();
#endif
//// FOXBEEP() << resultofexec << ":" << __FUNCTION__ << " your eye doctor like zoomss..";
}
bool BigFox::event(QEvent * ev) {
const int nr = ev->type();
switch (ev->type()) {
case QEvent::TouchBegin:
case QEvent::TouchUpdate:
case QEvent::TouchEnd:
{
QTouchEvent *touchEvent = static_cast<QTouchEvent *> (ev);
QList<QTouchEvent::TouchPoint> touchPoints = touchEvent->touchPoints();
if (touchPoints.count() == 2) {
const QTouchEvent::TouchPoint &TpointA = touchPoints.first();
const QTouchEvent::TouchPoint &TpointB = touchPoints.last();
const qreal linedistance = QLineF(TpointA.pos(), TpointB.pos()).length(); //// 1111
const qreal linestartpos = QLineF(TpointA.startPos(), TpointB.startPos()).length(); //// 222
bool zoomIn = false;
const qreal oldFaktorNow = zoomFactor();
/// ZOOMMAX = 500%
qreal xmax = qMax(linedistance, linestartpos);
const qreal ticks = ((ZOOMMAX / 5) / 100) * PERCENTZOOMSTEEPS; /// up down by 8%
//// is zoom in or out ?
const qreal goZoomFaktor = (linedistance == xmax) ? oldFaktorNow + ticks : oldFaktorNow - ticks;
//// if fingers go out save new state
if (touchEvent->touchPointStates() & Qt::TouchPointReleased) {
ZoomNewValue(goZoomFaktor);
}
}
}
default:
break;
}
return QWebView::event(ev);
}
