I'm an uber noob at programming in KDE/Qt and it's a bit different from Delphi in Windows but I think I'm getting the hang of it. Anyway, I'm trying to lay down a KHTMLPart onto this form with this code:

Code:

browser = new KHTMLPart(view_box, "browser");

where browser is a KHTMLPart defined in the mainwindow's class definition and view_box is a QVBox. Seems like pretty basic code but then I get the error:

Code:

52: undefined reference to `KHTMLPart::KHTMLPart[in-charge](QWidget*, char const*, QObject*, char const*, KHTMLPart::GUIProfile)'

so in an effort to just get *something* working, I use the example code here
which is straight from KDE 3.1 Reference material and it blew up as well! So weird, I thought this would be easy :rolleyes:

Looks like you're neglecting to include some header files. Can you post the program that won't compile?

I can't at the moment, sorry, but I do believe I had included: khtml_part.h for the main browser widget...I mean is there anything else needed?

maybe you should add $(LIB_KHTML) to your "automake config" so it can link.

Here is some additional code to make the browsing optimal, this information is somewhat hidden in the KDE docs.

Code:

#include <qlayout.h>



#include <khtml_part.h>

#include <khtmlview.h>

#include <kparts/browserextension.h>



WebSidebar::WebSidebar(QWidget *parent, const char *name)

  : QWidget(parent, name)

{

  QBoxLayout *layout = new QHBoxLayout( this );



  khtml_ = new KHTMLPart(this, "KHTMLPart");

  layout->addWidget( khtml_->view() );  // Streches widget



  khtml_->setJScriptEnabled(true);

  khtml_->setJavaEnabled(true);

  khtml_->setMetaRefreshEnabled(true);

  khtml_->setOnlyLocalReferences(false);

  khtml_->setPluginsEnabled(true);



  // Connect signals for browsing

  connect( khtml_->browserExtension(), SIGNAL(    openURLRequest(const KURL&, const KParts::URLArgs&) ) ,

          this,                        SLOT( slotOpenURLRequest(const KURL&, const KParts::URLArgs&) ) );

}



// Open a new url in the khtml widget

void WebSidebar::slotOpenURLRequest(const KURL &url, const KParts::URLArgs & /* args */)

{

  khtml_->openURL(url);

}

And indeed, you need $(LIB_KHTML) in the LDADD rule of the Makefile.am. If you look in your admin/ folder, you notice LIB_KHTML is an alias for '-lkhtml', which tells g++ to link to libkhtml.so
