A suitable example is: https://bug-4091-attachments.webkit.org/attachment.cgi?id=3092 The top right frame should display a PDF, but instead it just gets downloaded. This is a regression from previous behaviour. 464156 1 ap 2011-09-08 10:44:25 -0700 Yes, PDF is not yet working in subframes in WebKit2. I'm surprised that there doesn't seem to be an earlier report in Bugzilla. <rdar://problem/8750378> 477857 2 109668 ap 2011-10-04 12:55:11 -0700 Created attachment 109668 part 1 First part - not very usable yet, but some things work, and I'd like to proceed with smaller patches. Known limitations: Zooming, HiDPI Accessibility (not sure how much can be done for PDF yet). Not all mouse events are handled yet. You can click in scroll bar, but not drag. Keyboard events (PgUp/PgDown etc) are not handled yet. No support for annotations, such as forms. No support for auto-printing (scripts in PDF). No progress when loading. No HUD. Not sure if I need to implement Plugin::snapshot(). Dynamic scroll bar style changes don't work. No rubberbanding when scrolling (that doesn't work for iframes either yet). 477858 3 webkit.review.bot 2011-10-04 12:58:11 -0700 Attachment 109668 did not pass style-queue: Failed to run "['Tools/Scripts/check-webkit-style', '--diff-files', u'Source/WebCore/ChangeLog', u'Source/WebCor..." exit_code: 1 Source/WebKit2/WebProcess/Plugins/PDF/BuiltinPDFView.h:34: Code inside a namespace should not be indented.

Most plug-ins don't have localized descriptions, with the exception of Java and QuickTime. I'm planning to make these localizable in a later patch (forgot to mention that in the list of unfinished things). > Is there a way to arrange for these to be inlined? I wanted to avoid including PluginView.h in BuiltinPDFView.h. Not sure which consideration should be stronger in this case. > Seems that here in this local function we could just call this “page”. Not changing yet, since this code is largely a placeholder (we need to show all pages, and nicely position them). > Define inside the if statement? > Early return instead of nesting the if? Changed. This is copy/pasted code, and I initially wanted to keep it identical to original to make refactoring a little easier, but that's extremely insignificant compared to other code differences with FrameView and RenderLayer. > The idiom here is a bit awkward. Could we instead have sets of braces and two separate state savers? These will be separate functions soon, when full PDF is rendered. > I think it’s nicer to separate out #if things rather than having them in the same paragraph with the rest. Just staying in sync with Plugin.h here. > The m_pdf prefix here is a little ugly. Is there some other clever way to name this that avoids the acronym. Maybe m_contentDocument? I've been thinking about this for some time (having the same alternative in mind), and I'm not sure if it helps. There are so many "content" things in view and widget classes that I don't want to add more. Also, PDF document is not what we usually think of as "document" in WebKit. > Ideally these are all #if ENABLE(BUILT_IN_PDF_VIEW) instead of #if PLATFORM(MAC). Or something like that. Direct PLATFORM #ifs are not great. I chose to match existing WebKit2 checks for main frame PDF for now. Also, historically there was no interest to implementing built-in PDF support from other ports (e.g. PDFDocumentImage is still under USE(CG)). Addressed the rest of comments. Thanks for review! 478003 7 109668 ap 2011-10-04 15:28:39 -0700 Comment on attachment 109668 part 1 Committed <http://trac.webkit.org/changeset/96653>. Clearing review flag and not closing the bug, since it's not done yet. 481954 8 ap 2011-10-11 15:17:51 -0700 Remaining issues: Zooming, HiDPI No support for annotations, such as forms. No support for auto-printing (scripts in PDF). No progress when loading. No HUD. Context menu lacks PDF specific items. Custom CSS scrollbars are ignored. PostScript documents are not automatically converted to PDF for display. No interaction with PDF content (text selection, search, links or forms). No rubberbanding when scrolling (that doesn't work for iframes either yet). Accessibility (not sure if there is any meaningful work to do here). 486234 9 ap 2011-10-18 12:37:50 -0700 > Custom CSS scrollbars are ignored. Simon tells me that this is correct. An embedding document should not affect embedded one. I think that current functionality lets us close this bug. Please file separate bugs for details that still don't work and are important for you. 1961329 10 109668 09matches-suspect 2023-06-13 07:55:54 -0700 Comment on attachment 109668 part 1 How do I get use the patch?
