myqml.qml
RoundButton
id: roundButton1
Text
anchors.fill: parent
color: "white"
text: "print"
onPressed:
var stat = rectangle.grabToImage(function(result)
Serv.print(result.image); //result.image holds the QVariant
);
console.log("Success: ", stat);
serv.cpp
void Serv::print(QVariant data)
QImage img = qvariant_cast < QImage > (data);
QPrinter printer(QPrinter::HighResolution);
QPrintDialog dialog( & printer, 0);
if (dialog.exec() != QDialog::Accepted)
return;
QPainter painter( & printer);
painter.drawImage(QPoint(50, 50), img);
painter.end();
it print my rectangle but first time i click on the print button the dialog window doesn't bring up it runs but in the back and i can't see it until click again on the button .whats the problem?

If I understand your question clearly... the QPrintDialog isn't popping up correctly. Maybe trydialog.setModal(true)?
