You are using webcat with the recommended QtWebkit version linked in the description?

Ingvix's picture

No, I wasn't. Now I tried it though but it left webcat all white and no pages would show. Does it require some kind of configuring? I'm on Xperia X.

llelectronics's picture

Then I think you might've done something wrong.
Execute it from a terminal to see the error message.

Ingvix's picture

EDIT: Got it to work. Had to refresh and update some other webkit packages. Scrolling is a smoother now.

Kabouik's picture

I'm a bit lost regarding which rpms to download for upgrading Qtwebkit. Some comments above say it should be 10.43.1 and not a newer version, but this version is not available in the link supplied.

I totally concur with Olf that a metapackage here would have been more convenient, especially as WebCat seems to perform better in all regards with this upgrade. Few people will go through the hassle of manually picking 5 rpms from a website and then manually installing them now that we are all used to using convenient stores like Storeman, and even if one wants to do it like me, it seems the right packages are not on the website anymore.

This is a pity if the best performance and functionality are to be expected with these packages. In any case, thanks again for the great work. I hope I can manage to upgrade Qtwebkit to the right version and enjoy the perfect WebCat experience.

[Edit] My bad, it seems the link in the description now points to an archive and not the list of packages seen in the comments.

llelectronics's picture

You are right. Especially as the mer obs contains sometimes only dev builds that might not even work. 

The reason I hesitated back then and also now to upload stuff here is because I fear the newer packages might be not 100% compatible. Especially when it comes to the account creation/login in settings that I cannot update test all to make sure it is working with my qtwebkit upgrade. The same goes for some other third party apps using this qtwebkit. 

So if I add those packages here it needs to be with a big fat disclaimer.

Kabouik's picture

You got my vote for packages here + scary disclaimer, that would be the most convenient I think, and it might actually be less error prone from a user point of view (no risks of installing wrong versions as Olf mentioned).

olf's picture

Kudos to llelectronics for publishing his QtWebkit 5.212 RPMs in a separate repository at OpenRepos.

@llelectronics, can you please update the link to your Mer-OBS repo in WebCat's description above with https://openrepos.net/content/llelectronics/qtwebkit-5212

llelectronics's picture


Kabouik's picture

Thanks llelectronics for putting the packages on Openrepos! I wish they could install from the Storeman or Warehouse but it seems they still have to be downloaded manually, right? At least I had to, but that might be because I already had the previous dev packages installed manually from some months ago.


Regarding the disclaimer you've put on the corresponding page:

You need to install the original packages in order to upgrade to a new SailfishOS release.

Do you think it might be the issue I'm having here (last paragraph of this post)? If so, would you mind adding in the Qtwebkit and Webcat descriptions the command lines to revert back to vanilla Qtwebkit prior to a SF upgrade?

llelectronics's picture

Yes this is the issue. Please use pkcon download foldertodownloadto packagenames 

to download the original jolla rpms and install them.

Kabouik's picture

Thanks a lot for the tip. Hope it will fix my upgrade issue. Somehow I just managed to find libqtwebkit5-5.6.2+git5-1.3.1.armv7hl.rpm and qt5-5.6.3+git2-1.3.1.src.rpm using pkcon download *qt* (or variants like *libqt*). Am I missing something? I assumed I would find 5 rpms like in the Dev version in your other package.

Sorry to discuss that here and not in the Qtwebkit comments, but this is closely related to Webcat and it will be useful to others to find the information here.

llelectronics's picture

You should find all packages. Make sure to have a fresh cache (devel-su pkcon refresh)

0rion's picture

No webbrowser on Sailfish can properly display the website http://przystanki.bialystok.pl/

I hoped Webcat could do it... :(

llelectronics's picture

Looks almost fine to me on my tablet with QtWebkit 5.212 as backend for webcat. Only the search icon is not showing up for some reason. The rest works fine though on my initial test. Or is there anything special I should test on this site? 

0rion's picture

Very strange. I checked again and I can't search in any field (search icon appears but keyboard doesn't). I mean, I can't enter for example bus stop number or street name.

Webcat 2.9.7 with default settings, Intex Aquafish, Sailfish OS

llelectronics's picture

You are right this is indeed not working. I can get to the searchbar and list but searching clears the list completely with Qt 5.212. 

So I think this website is not compatible with Qtwebkit. There is nothing I can do about it. You could report this bug to qtwebkit 5.212 itself and maybe they are able to fix it.

objectifnul's picture

How do I enable/disable javascript in webcat? Didn't see it in settings.

llelectronics's picture

It is indeed not possible as I don't offer that in settings.

Bocephus's picture

FFS, yes it's "a u", and how is that even relevant as pertains to Webcat? What's your diagnosis?

skyjumper's picture


Are you able to add cookie control? I know we can delete them, but the ability to control session and third party cookies would be great.


ps and a small thing - it should be "open a url", not "open an url"

llelectronics's picture

I currently don't see a way to distinguish between them with API QtWebkit offers.

olf's picture

"u" is a vowel, not a consonant, right?
So why should it not be "an u..."?

skyjumper's picture

That's because of the lovely intricacies of the English language. Because the U in url sounds like a consonant - y, we use "a" instead of "an".

olf's picture

So the matter of "an" vs. "a" depends on pronouncing it "yurl" or "U-R-L", right?

Well, I (long ago) learnt, that a "y" is treated as a vowel depending on its pronunciation (e.g., "year" vs. "lovely", but I cannot think of any leading "y" being pronounced "ie", thus this is a non-issue WRT "a" vs. "an"), but vowels being treated as consonants is new to me; do you have a pointer at hand for further reading on this matter?

Sorry for bugging you with such an off topic question (some friends call me "language nazi", but that is usually about expressing oneself concisely, not grammar).

skyjumper's picture

Oh I understand completely - badly worded sentences or grammer is frustrating... Have a look at this: http://www.writersdigest.com/online-editor/a-before-consonants-and-an-be... - see what you think :-)

olf's picture

Thanks, that site provides some nice distraction for the evening.  But it were rather your statements (as we both seem to be in accordance on the grammar rule), which made me reconsider the original point:

a. My initial statements were too brief and thus not concise (in thinking *and* writing). ;\  Specifically, I would / should have spelled it "an URL", denoting to address the classic TLA of "Uniform Resource Locator", which is pronounced "U-R-L".

b. Thinking about it, I realise that many tend to use "url" as a simple noun nowadays, which is pronounced "yurl", hence should be spelled as "a url".  Well, many acronyms were always handled like this, e.g. "snafu", but OTOH think of "YMCA".

I personally still tend to use style a. (and pronounce it as single letters), but ... yes, I am growing old and language is permanently evolving.  Is this line of thoughts comprehensible and does it make sense for you?

skyjumper's picture

Yeah, makes sense to me. Though I would always says the letters as compared to saying the word - that seems strange. Though "an URL" seems stranger!

olf's picture

Thanks, as your last statement ultimately made me understand, that it ought be "a U" in any case (i.e. never "an U"), as even the single letter U is pronounced "ju", right?

Hello! Sometimes at surfing a part of the page doesn't display (only white background). To make the page displayed need to refresh the page, or TO OPEN BOOKMARKS AND GO BACK TO THE PAGE. How to fix this problem?
