Currently writing an app that should be able to quicklook webarchive. Copied data from safari also happens to be saved as .webarchive.
Is there a way to show them ? Or do I need to convert the webarchive, or by extracting html first ?
You should be able to use the WebArchive class from WebKit or my open source implementation DTWebArchive: https://github.com/Cocoanetics/DTWebArchive
This gives you access to the individual parts that make up the web archive, which is essentially just a binary plist.

i have one app installed which is using arbortext ptc isoview /creo plugin to show files, so i wanted to make app to take snapshot of it in my IE, but cant find the way to load pzv file, if you just drag and drop it, does not work, i also tryed loadin via html, but seems my params are wrong?
solved, by ripping 3 java scripts and displaying full screen pvz file in webbrowser and then taking snapshot
I need to work on multiple PDF files and because of annotating those files, I prefer to use Preview built-in app for Mac OSX.
If I am in the middle of one PDF file say on Page 5, and I transit to some other PDF file and come back to the previous file, then I always get the first page of that PDF.
Is there any setting which I can use so that I always get the page from where I left?
Not sure what the problem is, mine works as you seem to want it to. Maybe your Preferences are set differently. Here are mine.
Cocoa's WebView can display .webarchive files. The ones I try to display come from the pasteboard, e.g. when copying parts of a web page in Safari or Mail.app.
The issue I am having is that webarchives from Mail and Notes won't display in a WebView, while webarchives from Safari do.
I looked inside the data of those archives (BBEdit can decypher their binary plist format and show it as XML nicely) and found that the issue is caused by the unusual URL references Mail (and Notes) puts in there:
<key>WebResourceURL</key>
<string>x-msg://4/</string>
If I remove that entry or change it to something using http://, WebView suddenly can display such archives.
Now, how do I solve this in general in my code?
I don't want to have to decode the webarchive, find the WebResourceURL entry and remove it before passing the archive to the WebFrame for loading.
I wonder if there's something else I have to set up with either the WebView or its main frame to make this work.
I noticed that Xcode can show these webarchives just fine, suggesting that Xcode uses WebKit in a more "proper" way that solves the issue. But then, maybe that's just because it has NSWebFrame load the archive from disk, while my code loads it from a CFData object - when loading from a file, WebKit may be using that file URL as the base URL, while it only chokes on it when it doesn't get a usable URL at all.
I have created a little demo project for Xcode here: http://files.tempel.org/Various/Mail-WebArchive-Display-Issue.zip
It includes both an original archive from Mail ("mail-bad.webarchive") and a fixed one ("mail-good.webarchive"), both of which are displayed in two webViews in the demo app.
I had also opened a Tech Support Indident (TSI) with Apple DTS, and the responded that I should file a bug. The bug report can be seen here: http://openradar.appspot.com/radar?id=2843403
After brooding over what Xcode might be doing I found a solution:
This does not work:
WebArchive *archive = [[WebArchive alloc] initWithData:webData];
[[webView mainFrame] loadArchive:archive];
But this does:
[[webView mainFrame] loadData:webData MIMEType:#"application/x-webarchive" textEncodingName:#"" baseURL:NULL];
So, the explicit function to load the archive is faulty while the one that wants an explicit URL, even though I give it none, works.
Go figure.
I'm writing a Quicklook generator plugin for a GPS logging file format (.fit files). I've shoved something together which loads the file and plots the path using the NSGraphics/NSBezier stuff:
(the horrible code for the above can be found here)
This is fine, but it would be much nicer to display this over Google Maps data or similar (the recorded tracks cover a fairly small distance - e.g the above covers about 20km by 10km - too small to display on a single map of the earth, so the map needs to be dynamically loaded somehow)
Things I've tried so far:
Returning HTML which shows a Javascript GMap instance. Doesn't work as the Quicklook HTML rendering doesn't allow Javascript (or Flash, Java etc)
Returning HTML containing a static Google Maps image. Quicklook wont load remote images.
Getting a NSGraphicsContext and displaying a standard WebKitView into this, modified from some thumbnailing code - this errors because you cannot initialise WebKit from a secondary thread (which seems to work fine for thumbnails, but not previews?)
With 2. I could possibly download the static Google Map image in ObjC, then display that with HTML, but the static map isn't ideal (fixed size so no zooming, and potentially slow to initially load)
I came across MacMapKit which I've not tried yet, but since it's WebKit based, I suspect it will have the same issue as 3.
Is there some way of displaying a map in a Quicklook that I am overlooking?
trying to get Google data directly in your generator (whatever way you try to do it) is not possible as the host of your plug-in is sandboxed and denies any connection to the network
trying to return HTML data and some clever javascript won't work either as the Quick Look panel also protects against network access for security reason and there is no public way to work that around
I am afraid you won't find a real solution to your problem, except by using your own map data.
Still, your use case is interesting and you should file a bug to Apple's Bug Report website.
I am currently writing an application working with specially prepared image data. Another tool prepares the images (basically PNGs with additional data stored in the meta-data section). Now my tool works with these files, but not with all PNGs, so "we" decided to use a different file extension. So far, so good.
Now, because I am a lazy sack I implemented some file type registration to allow double-clicking on the file and opening it in my application (no problem at all).
And here is my Question:
It would be cool if the windows explorer could still show me the thumbnail previews for my files. Since they basically are still PNG files, it should be possible without writing my own shell extension (at least I believe so).
I quickly tried to copy all registry keys and values from HKCR.png to HKCR.mInDat (my file name ext) and it worked. However, I would prefere knowning what I am doing ;-)
Which of the registry settings are responsible for the thumbnail preview control and which can I use to get the preview for my file types?
I tried to google it, but I failed, since it seems I am unable to come up with the right buzz-words to find the info I need. Please, help me.
Thank you!
Yours,
