How to change the saving directory of a pdf printed plot?

[yannwilfried]

Hi all,

i want to print a plot as pdf and everything is working fine. My problem is to set an output directory for my pdf. I could'nt find a method like setOutputDirectory for QPrinter. Using getSaveFileName, i can set a directory but if i change the directory using the file dialog, my pdf is still saved at the chosen working directory of my getSaveFileName method.

void GraphicTools::printPDF()
{
	QwtPlotPrintFilter filter;
	int options = QwtPlotPrintFilter::PrintAll;
	options &= ~QwtPlotPrintFilter::PrintBackground;
	options |= QwtPlotPrintFilter::PrintFrameWithScales;
	filter.setOptions(options);
 
	QPrinter printer(QPrinter::HighResolution);
	QPixmap pixmap(ui.qwtPlot->size());
	pixmap.fill(Qt::transparent);
 
	if(!pixmap.isNull())
	{
		QString savingDirectory = QDir::currentPath();
		QString fileName = QFileDialog::getSaveFileName(this, tr("Save the file as PDF"), 
			savingDirectory, tr("(PDF Files)*.pdf"));
		QString savingDirectory = strippedPathName(fileName);
		if (!fileName.isEmpty())
		{
			printer.setOutputFormat(QPrinter::PdfFormat);
			printer.setOutputFileName(strippedName(fileName));
			ui.qwtPlot->print(printer, filter);
			QMessageBox::information(this, tr("PDF was saved at..."), 
				tr("%1 was saved at %2").arg(strippedName(fileName), savingDirectory), 
					QMessageBox::Ok);
		}
	}
 
}

void GraphicTools::printPDF()
{
	QwtPlotPrintFilter filter;
	int options = QwtPlotPrintFilter::PrintAll;
	options &= ~QwtPlotPrintFilter::PrintBackground;
	options |= QwtPlotPrintFilter::PrintFrameWithScales;
	filter.setOptions(options);

	QPrinter printer(QPrinter::HighResolution);
	QPixmap pixmap(ui.qwtPlot->size());
	pixmap.fill(Qt::transparent);

	if(!pixmap.isNull())
	{
		QString savingDirectory = QDir::currentPath();
		QString fileName = QFileDialog::getSaveFileName(this, tr("Save the file as PDF"), 
			savingDirectory, tr("(PDF Files)*.pdf"));
		QString savingDirectory = strippedPathName(fileName);
		if (!fileName.isEmpty())
		{
			printer.setOutputFormat(QPrinter::PdfFormat);
			printer.setOutputFileName(strippedName(fileName));
			ui.qwtPlot->print(printer, filter);
			QMessageBox::information(this, tr("PDF was saved at..."), 
				tr("%1 was saved at %2").arg(strippedName(fileName), savingDirectory), 
					QMessageBox::Ok);
		}
	}

}

To copy to clipboard, switch view to plain text mode 

Thanks for any advices.

From what I see you set only the name of the file using QPrinter::setOutputFileName(), not the whole path (you're using strippedName() there).

A whole day to search for a solution . I need to drink more coffee. Many many thanks Wysota.

No, you need to sleep more
