question about KHTMLPart

hi all,
I am using KHTMLPart to display rich text chatting messages. But I cannot figure out how to enable copy and paste functionalities(like Ctrl-v, Ctrl+v or using mouse popup menu). should I implement by myself or there is some setting in this class?

Can anyone help me? Thanks in advance.

AFAIK, you have to implement that by hand.

All the help you can get from KHTML part is some events for mouse clicks, and from Kapp you can have the standard actions (cut, paste and copy are there)

On my system they are just OK. I've used KHTML part even on low spec machine, but still it is responsive.

What kde version are you using?

Hi antonio,

I am using KDE 3.3.2 with some patches. Probably it's not the khtmlpart problem. I've tried my code on another machine with gentoo system(kde 3.3.2), it works very well.

could you please help me for one more question? I've connect browserExtension's signal
openURLRequest, but it seems that it never grab the email addresses and I couldn't find a proper way to get those email addresses when user click on them. could you give some hints for this?

many thanks!

Sorry, but I haven't understood: do the signal get generated (when you click on a mai link) or does it not even get generated?

yes, the signal is generated.

what I have done is like following.
I subclass from KHTMLPart, in the constructor,

	Source code
1 2 3	QObject::connect(browserExtension(), SIGNAL(openURLRequest(const KURL &, const KParts::URLArgs &)), SLOT(slotLinkClicked( const KURL &)));

then, in the slot slotLinkClicked

	Source code
1 2 3 4 5	void EvaChatView::slotLinkClicked( const KURL & url) { printf("KURL: %s\n", url.host().latin1()); // do something }

It turns out, when I wrote string
"<a href="http://www.qtforum.org">http://www.qtforum.org</a> "
into the class, and then clicked the url shown on the window, I got "KURL: www.qtforum.org" printed out. It just work fine.

But, whenever I wrote
"<a href="mailto:xxx@qtforum.org">xxx@qtforum.org</a>"
into my subclass of khtmlpart, I clicked on it, the console shows
"KURL: (null)"

Is there something wrong? I got stucked here for a couple of days, I thought to grab email address might need some other signal or method, that was why I said those words in the prevouis post.

sorry for my bad expression.

Well, try printing url.url(), this should print the unparsed string the KURL gets constructed with. It should be mailto:...

If I'm not mistaken url.host() works only with file: and http,ftp: URL types. To parse email addresses you should use url() and then extract the host manually.

I hope this has helped you
