QPrintDialog isn't popping up correctly












0














I have a print button in a QML pop up with this code that print my rectangle as a QImage:



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?




I use Qt 5.9.1

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