Re: kwordpart plugin not found

Just to be save ( because I sourced the bashrc many times ) I rebooted my machine and checked all the variables. They are set according to what you've written in this post. I also recalled you wrote that kde4-config is for kde4 so I executed a few commands:

[user@localhost1016:~/koffice-2.1/ ]$ kde4-config --expandvars
[user@localhost1016:~/koffice-2.1/ ]$ kde4-config --prefix
/usr

never tried kdebugdialog, but I'll do my best.

That indicates that the Part is being loaded successfully. Make sure that the KPart is properly parented to the appropriate parent widget.

OK, I don't quite understand that. This works for the katepart, shouldn't it also work with kwordpart in exactly the same manner? The parent widget is a QVBoxLayout, the piece of code above is preceded by:

Code: Select all
QWidget* privateLayoutWidget = new QWidget( parent );
privateLayoutWidget->setObjectName("privateLayoutWidget");

QVBoxLayout* layout2 = new QVBoxLayout( privateLayoutWidget);
layout2->setObjectName("layout2");


I guess that should be OK then...right??

I'm think you guys are right about the kwordpart being loaded, how else would I get this message then?

Calling appendChild() on a null node does nothing.
kword(17654)/kparts KParts::Part::slotWidgetDestroyed: deleting part "document_0


this message shows up after the rest of the
...does not offer qt_plugin_instance function
messages and after I close my app.

My previous remark isn't valid I think, because after debugging I saw that the
If(factory)
is false so it never enters it. So there is no way that the kwordpart is found....I guess :?

Re: kwordpart plugin not found

Tried some new code to get some services back, this is the code

Code: Select all
KService::List offers=KServiceTypeTrader::self()->query("KParts/ReadWritePart");
KService::List::const_iterator iter;

for(iter = offers.begin(); iter < offers.end(); ++iter)
{
   QString error;
   KService::Ptr service = *iter;

   KPluginFactory *factory = KPluginLoader(service->library()).factory();

   if (!factory)
  {
     kError(5001) << "KPluginFactory could not load the plugin:" << service->library();

    continue;
  }
   
  kDebug() << "Load plugin:" << service->name();
}


this is the gdb debug output:
myapp(18472)/ ReportEditor::initialiseReportArea: Load plugin: "Embedded Advanced Text Editor"
(gdb) next
(gdb) next
(gdb) next
(gdb) next
(gdb) next
myapp(18472)/ findLibraryInternal: plugins should not have a 'lib' prefix: "libkwordpart.so"
myapp(18472)/ findLibraryInternal: plugins should not have a 'lib' prefix: "libkwordpart.so"
myapp(18472)/ kde4Factory: The library "/home/user/koffice-2.1/install/lib/kde4/libkwordpart.so" does not offer a qt_plugin_instance function.
(gdb) next
(gdb) next
kword(18472) ReportEditor::initialiseReportArea: Load plugin: "KOffice Word Processing Component"
(gdb) next


And then the for loop ends, it seems like the kwordpart is found...is it?

The previous code was likely fine.
Try this to perform the loading instead.

Code: Select all
m_part = factory->create<KParts::ReadWritePart *>(this, this, "kwordpart" );

Sorry for the late reply, but had a long weekend. I tried the suggestion of bcooksley but this is what I get:

Code: Select all

I suspect that the my issue has something to do with the last message in my out when running my app.

Code: Select all
Calling appendChild() on a null node does nothing.


This statement is spit out after the createGUI(m_part) statement is hit.I'm googling on this,but so far no success. Is there anybody who has seen this before?

Oops, try this instead.
Code: Select all
m_part = factory->create<KParts::ReadWritePart>(this, this, "kwordpart" );

Re: kwordpart plugin not found

Tue Jan 26, 2010 9:15 pm
I've also tried that one to after I got the error message but that didn't help either. What I see on the console as output of my program are the first couple of lines equil to the output when I start kword ( see 2 postings before ) via the console up to the line

Code: Select all
kword(31262)/kdecore (KLibLoader) kde4Factory: The library "/home/user/koffice-2.1/install/lib/kde4/pictureshape.so" does not offer a qt_plugin_instance function


So this is the last line and it's followed by

Code: Select all
Calling appendChild() on a null node does nothing.


Thus my program never reaches the line

Code: Select all
kword(31262)/kdecore (KLibLoader) findLibraryInternal: plugins should not have a 'lib' prefix: "libxsltexport.so"

Re: kwordpart plugin not found

After much experimenting and help of dfaure it works. The messages I received on the console could be ignore since the plugin is loaded as it should be. But the preferred way is this:

Code: Select all
 
KService::Ptr service = KService::serviceByDesktopPath("kwordpart.desktop");
  KParts::ReadWritePart *m_part = 0;

  if (service)
  {
      m_part = service->createInstance<KParts::ReadWritePart>(0);
      if (m_part)
      {
          m_part->setParent(this);
          this->layout()->addWidget( m_part->widget() );
          m_part->openUrl(KUrl("/home/user/report.fodt"));
      }
      else
      {
          return;
      }
  }
  else
  {
      qDebug("service kwordpart.desktop not found");
  }

  OGUINameSpace::getMainWindow()->createGUI(m_part);


....and kword works.

Thanks to dfaure of the kde development team and co-designer of the KParts-technology
