Create a PDF from Qt Creator

[TheCipo76]

@mrjj No, "PrimoPDF.pdf" wasn't created..

the code you have posted is very similar..

@TheCipo76
Yep and i get a e:/test.pdf so not really sure why you dont get any.
does it try to print to real printer ?

Can you try

void printv3() {

  QPrinter printer(QPrinter::HighResolution);
  printer.setOrientation(QPrinter::Landscape);
  printer.setOutputFormat(QPrinter::PdfFormat);
  printer.setPaperSize(QPrinter::A4);
  printer.setOutputFileName("test.pdf");

  QPainter painter;
  painter.begin(&printer);

  painter.drawText( 200,200, "HELLO" );
  painter.end();

}

That give me a test.pdf in the build folder

and expected result

@mrjj i've tried with no luck

test.pdf was not created..

@TheCipo76
Really odd. I cant guess sorry. Sample works here.
You use the code directly as is ?

[TheCipo76]

@mrjj Yes, copied and pasted

QPrinter printer(QPrinter::HighResolution);
      printer.setOrientation(QPrinter::Landscape);
      printer.setOutputFormat(QPrinter::PdfFormat);
      printer.setPaperSize(QPrinter::A4);
      printer.setOutputFileName("test.pdf");

      QPainter painter;
      painter.begin(&printer);

      painter.drawText( 200,200, "HELLO" );
      painter.end();

[mrjj]

and you also searched for test.pdf to make sure
its not created any where else ?

Very odd.
Can you try this code. it let u select save location
if that dont work. something up with your Qt.

void printv4() {
  QPrinter printer(QPrinter::HighResolution);
  printer.setOrientation(QPrinter::Landscape);
  printer.setOutputFormat(QPrinter::PdfFormat);
  printer.setPaperSize(QPrinter::A4);
  QString fileName = QFileDialog::getSaveFileName(0,"file", "c:\\", "pdf (*.pdf)");
  printer.setOutputFileName(fileName);

  QPainter painter;
  painter.begin(&printer);

  painter.drawText( 200,200, "HELLO" );
  painter.end();

}

Super :)
So on mac it seems the file go somewhere else
if no path. maybe a read only place.
So when we tell the exact location , it does work :)

@TheCipo76 said in Create a PDF from Qt Creator:

printer.setOutputFileName("PrimoPDF.pdf");

When launched from QtCreator, the default working directory is set to:
MyApp/Contents/MacOS/

When launched from the finder, the path is usely the user directory, but actualy it is the root directory (/) and obviously nothing is written (wrong permissions)

IIRC the standard path is

/Users/yourUserName/Library/Application Support
