Bug 1091112 - Print dialog doesn't get focus automatically, if e10s is enabled

Ok, this is a matter of proxying the dialog to the parent like we do with Windows and Linux.

This should also fix Bug 1091103 - Print dialog does not use retina resolution with e10s enabled.

So here we go again. I think this is a matter of finding out what the dialog needs, serializing it, deserializing it, big bada boom.

nsIWebBrowserPrint::enumerateDocumentNames is something I need to send over...

nsPrintDialogServiceX::Show seems to have all of the hints. Basically, I need it so that what's deserialized can provide enumerateDocumentNames for this:

  char16_t** docTitles;
  uint32_t titleCount;
  nsresult rv = aWebBrowserPrint->EnumerateDocumentNames(&titleCount, &docTitles);
  if (NS_SUCCEEDED(rv) && titleCount > 0) {
    CFStringRef cfTitleString = CFStringCreateWithCharacters(NULL, reinterpret_cast<const UniChar*>(docTitles[0]),
                                                             NS_strlen(docTitles[0]));
    if (cfTitleString) {
      ::PMPrintSettingsSetJobName(settingsX->GetPMPrintSettings(), cfTitleString);
      CFRelease(cfTitleString);
    }
    for (int32_t i = titleCount - 1; i >= 0; i--) {
      free(docTitles[i]);
    }
    free(docTitles);
    docTitles = NULL;
    titleCount = 0;
  }

And then I also need it to be able to spew out NSPrintInfo. Yech:

NSPrintInfo* printInfo = settingsX->GetCocoaPrintInfo();

NSPrintInfo documentation . Example usage.

So it looks like an NSPrintInfo wraps a dictionary, like GTK. So maybe I can just extract that dictionary, send it on down to the content process, where it'll replace the nsIPrintSettingX's NSPrintInfo with a new one.

So let's break this down:

See if the title for nsIPrintSettings is good enough for PMPrintSettingsSetJobName. Looks like Title and DocURL is mostly ignored. WTF.

Serialize and send the document names over. Actually, we just need to send one, since the first one is the only one that nsPrintDialogX listens for.

The dictionary is keyed on NSStrings. The value can be any number of things, I'm afraid… I see NSPrinter, NSNumber, NSString, NSDate, NSURL

When deserializing, it looks like we can get an NSPrinter back via [NSPrinter printerWithName:@"NAME"]

So I think instead of passing an array of key-value pair, I just add fields to PPrintingTypes.ipdlh - and make sure the primitives get initialized as empty.

Constants we need to serialize

NSPrintPrinter

An NSPrinter object—the printer to use.

Available in OS X v10.0 and later.

Solution : Store this in printerName.

Solution: Just store this in printerName.

NSPrintCopies

An NSNumber object containing an integer—the number of copies to spool.

Available in OS X v10.0 and later.

Solution: Store this in numCopies.

NSPrintAllPages

An NSNumber object containing a Boolean value—if YES, includes all pages in output.

Available in OS X v10.0 and later.

Solution: Add a new bool field - printAllPages.

NSPrintFirstPage

An NSNumber object containing an integer value that specifies the first page in the print job.

Available in OS X v10.0 and later.

Solution: Store this in startPageRange

NSPrintLastPage

An NSNumber object containing an integer value that specifies the last page in the print job.

Available in OS X v10.0 and later.

Solution : Store this in endPageRange.

NSPrintMustCollate

An NSNumber object containing a Boolean value—if YES, collates output.

Available in OS X v10.0 and later.

Solution: Add a new bool field - mustCollate.

NSPrintReversePageOrder

An NSNumber object containing a Boolean value—if YES, prints first page last.

Available in OS X v10.0 and later.

Solution: Store this in printReversed.

NSPrintJobDisposition

An NSString object that specifies the job disposition.

NSPrintSpoolJob, NSPrintPreviewJob, NSPrintSaveJob, or NSPrintCancelJob. See setJobDisposition: for details.

Available in OS X v10.0 and later.

Solution: Add a new short field - disposition

NSPrintPagesAcross

An NSNumber object that specifies the number of logical pages to be tiled horizontally on a physical sheet of paper.

Available in OS X v10.4 and later.

Solution: Add a new short field - pagesAcross

NSPrintPagesDown

Available in OS X v10.4 and later.

Solution: Add a new short field - pagesDown

NSPrintDetailedErrorReporting

An NSNumber object containing a Boolean value—if YES, produce detailed reports when an error occurs.

Available in OS X v10.4 and later.

Solution: Add a new bool field - detailedErrorReporting

NSPrintFaxNumber

An NSString object that specifies a fax number.

Available in OS X v10.4 and later.

Solution: Add a new string field - faxNumber

NSPrintHeaderAndFooter

An NSNumber object containing a Boolean value—if YES, a standard header and footer are added outside the margins of each page.

Available in OS X v10.4 and later.

Solution: Add a new bool field - addHeaderAndFooter.

Solution: Add a new bool field fileNameExtensionHidden

Solution: Store this in print options flags via nsIPrintSettings::kEnableSelectionRB. We'll need to add options to the common group.

NSPrintJobSavingURL

An NSURL containing the location to which the job file will be saved when the jobDisposition is NSPrintSaveJob .

Available in OS X v10.6 and later.

Solution: Store this in toFileName.

https://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSURL_Class/index.html#//apple_ref/occ/instp/NSURL/absoluteString

Have parent process create an nsPrintSettingsX, and hand it over to the dialog.

The thing we get back to give to the content process… make sure we serialize the NSPrintInfo dictionary.

Deserialize the document names for EnumerateDocumentNames for MockWebBrowserPrint

Using just the printer name, I think we need to get a reference to an NSPrinter.

An NSNumber object that specifies the number of logical pages to be tiled vertically on a physical sheet of paper.

Available in OS X v10.6 and later.

Available in OS X v10.4 and later.

Ok, time for a self-review: https://reviewboard.mozilla.org/r/9129/

What is up with printSettings is null error when attempting to print?
