[SOLVED] Using "open" methods in QPrintDialog and QFileDialog
-
I'm confused about the syntax here. The documentation implies that the call to open makes the connection between the accepted() signal and the arguments to open. So I have
@void SeismicCanvasWindow::showPrintDialog(){
QPrintDialog printDialog(thePrinter, this);
printDialog.setWindowModality(Qt::WindowModal);
printDialog.open(seismicCanvas, SLOT(printCanvas(QPrinter*)));
}
@With the corresponding slot:
@
void SeismicCanvas::printCanvas(QPrinter *printer){
int resolution, i;
QList<int> resolutions;resolution = printer->resolution(); resolutions = printer->supportedResolutions(); for(i=0; i< resolutions.size(); i++) if(resolutions[i] > resolution) resolution = resolutions[i]; printer->setResolution(resolution); cerr <<"Printer resolution is set to:" << resolution <<"dpi\n";
}
@This crashes every time the print dialog is closed, with either ok or cancel buttons. Clearly I am doing something wrong, but I get no error that the signal and slot aren't connected.
Any suggestions for my error?
Thanks Glenn

Bump... anyone?

Qt 4.8.4 has fixed the bug that was causing this problem.
