Qt 5.5 print bug on Windows?

Riki P

Hi,

the application I work on crashes on Windows if I

print a page
choose the 'Microsoft XPS Document Writer' printer and
press the button cancel when the system asks me the name of the XPS file

At first I thought the error was in my application but I found that the same happens in QtCreator.
In my case the crash happens in the slot connected to the signal paintRequested() of my QPrintPreviewWidget subclass:

void LabelsPrintPreviewWidget::printLabels(QPrinter *printer)
{
    if (!printer->isValid())
        return;
    QPainter painter(printer);    <- HERE 
    ...
}

The dialog to choose the name of the XPS file is shown when the line QPainter painter(printer); is executed and if I click on the Cancel button the application crashes.

Does anybody know if this an error in my application (and QtCreator) or is it a bug in Qt 5.5 (on Windows)?

Thanks
ciao

Hi and welcome to devnet,

If you can reproduce this with a minimal compilable example then it's likely a bug. You should check the bug report system to see if it's something known.

Thanks SGaist,

I searched in the bug report system but did not find a similar issue so I submitted a new bug report (QTBUG-48203).
