Bug 247541

Please report the webkit bugs to the appropriate component, not under konqueror.

OK, sorry. I will do that next time. Can you please explain me how to do that?

The way I proceeded: I was having problems with Konqueror, so I clicked on "Report Bug", which brought me here: https://bugs.kde.org/enter_bug.cgi?format=guided&product=konqueror&additional_info=OS%3A%20Linux%20%28i686%29%20release%202.6.32-24-generic%0ACompiler%3A%20cc&version=4.5.00%20(KDE%204.5.0). At step 2, I read the components carefully, but could not find webkit, so I decided to leave the default. Many thanks in advance.

You do not need to worry about this. I have fixed it so that crashes will be reported to correct component going forward.

That cannot be correct. Both kwebkitpart and khtml should behave the so long as Konqueror's "Middle click opens url in selection" setting found under "Settings->WebBrowsing" is checked. The only difference should occur if that option is left off (unchecked) in which case kwebkitpart should not respond to middle clicks at all. In other words, the "move mouse vertically to scroll on middle click" feature is not yet implemented in kwebkitpart. However, your description here make it seem that kwebkitpart will always navigate to or search for content from the clipboard whenever the MMB is clicked. If this is not the case, please elaborate on how to duplicate the issue...

As far as the other missing functionality. It is on the TODO list along with the "Smooth Scroll" functionality.

"Middle click opens URL in selection" was turned off intentionally in order to 
use middle-click to scroll pages vertically. But while this works normally 
with KHTML, it doesn't with kwebkitpart.

Now I see. Indeed, middle-click doesn't trigger the expected result (vertical 
scroll). However, although "Middle click opens URL in selection" is unchecked, 
middle-clicking with Webkit triggers a similar response nonetheless - I say 
"similar" because if last entry in the clipboard is a URL, rightclicking will 
open that URL within the tab. But if last entry in the clipboard is a word or 
a sentence:

- with "Middle click opens URL in selection" checked on KHTML, I am asked "Do 
you want to search the Internet for [...]?";
- with the "Middle click opens URL in selection" UNchecked on Webkit, instead, 
middle-clicking will automatically show a page with results from Google.

I believe this is not the intended behavior, since I did not initiate the 
search, but merely wanted to scroll the page vertically. According to your 
explanation, though, this feature is yet to be implemented, so it is my 
understanding that it should only fail to respond to any right-click, at that 
point. Hence, I believe this is not a feature request, but a bug that should 
be fixed.

Sorry if my explanation sounds convoluted and lacks any technical knowledge, 
but if you feel it still fails to clarify the issue, please don't hesitate to 
let me know, and I will try to add any missing detail.

Errata corrige:
"so it is my understanding that it should only fail to respond to any right-click, at that point" should read "so it is my understanding that it should only fail to respond to any middle-click, at that point". Sorry about that.

Huh ? Are we talking about middle clicking or right clicking ? Middle clicking whenever the above option is turned off should result in no action at all regardless of what is stored in the selection clipboard. The logic that is used in kwebkitpart is intended to prevent this from happening.

The prompt is missing in kwebkitpart and will be something that will be added for KDE 4.5.1 if allowed otherwise in KDE 4.6 (requires addition of a signal).

This should not happen and I am unable to duplicate it. It works correctly for me. If the option is not checked, I get nothing regardless of whether I have a url or regular text in the selection clipboard.

Well that should not happen and indeed I cannot duplicate it on here on my system with KDE 4.5.0 and the 0.9.6 version of kwebkitpart. Out of curiosity can you please tell me what version of the kwebkitpart library is installed on your system ? You can find it by looking for "libkwebkit.so*" under /usr/lib. Unless you have a rather old version of kwebkitpart, I do not see how this bug can occur.

No your explanation is perfectly fine. My response to it is based on the fact that I am unable to duplicate your problem.

Middle-click, of course. Sorry, I really don't know where the "right" bit 
comes out from, I just mistyped.

I see, this should explain that.

If I am correct, I only had to check the filename, and it says: 
libkwebkit.so.1.0.0.

It's OK, I thought it was a common problem, and I could contribute back to 
Konqueror after using it on a daily basis. Since it's mine alone, I'll switch 
back to KHTML for now, and give Webkit another try when Kubuntu Maverick is 
out. Many thanks for your assistance so far.

This is fixed now. You will get prompted before any searching is done just like KHTML.

There lies in the problem... Unfortunately you have a rather old version of kwebkitpart. Because of some mishap the latest version should say 0.9.6 and not 1.0.0. Perhaps that is confusing the distro packagers and they are not updating it ?? No idea, but you can rest assured this works in the latest version minus the "automatic scrolling" feature of course.

No it is not yours alone. It seems to be a distro problem. If you can poke whomever is responsible to update the kwebkitpart package from extragear that would be great. They should use the latest version for KDE >= 4.4. 

Anyhow, thanks for your report. I will close this bug report, but would you be so kind to open a new wishlist item ticket for the unimplemented "automatic scrolling" feature so it won't be forgotten ?  Thanks again.

Thanks for this!

Alright, so that's why. At least this is fixable.

OK, I will certainly try to!
