C++ (Cpp) KPrinter::setPageSize Examples

Example #1

void KstApp::immediatePrintToFile(const QString &filename) {
  KPrinter printer;
  printer.setPageSize(KPrinter::Letter);
  printer.setOrientation(KPrinter::Landscape);
  printer.setOutputToFile(true);
  printer.setOutputFileName(filename);

  view->print(&printer);
}

Example #2

bool KstIfaceImpl::printPostScript(const QString& url) {
  if (url.isEmpty()) {
    return false;
  }

  KstView *view = _app->viewObject();
  KPrinter printer;
  printer.setPageSize(KPrinter::Letter);
  printer.setOrientation(KPrinter::Landscape);
  printer.setOutputToFile(true);
  printer.setOutputFileName(url);
  view->print(&printer);
  return true; // FIXME: eventually return an error code
}

Example #3

void KstApp::slotFilePrint() {
  slotUpdateStatusMsg(i18n("Printing..."));

  KPrinter printer;
  printer.setPageSize(KPrinter::Letter);
  printer.setOrientation(KPrinter::Landscape);

  // FIXME: Make a better title for the printingdialog
  if (printer.setup(this, i18n("Print Data")))
