[Okular-devel] Creating new class

[Jakub Zakrzewski]

Hey guys,

few days ago I wrote that I want to implement a new feature in okular:
displaying the search results overview
using table of contents.

Now I'm playing with code and I want to make a copy of the ui/toc.cpp class
and the classes it uses:
tocmodel.cpp

What I did is:
I copied the ui/toc.(h|cpp) and ui/tocmodel.(h|cpp) files so I have
tocsearch.h, tocsearch.cpp, tocsearchmodel.h,
tocsearchmodel.cpp.

I also changed the classes names and references so they have 'Search' in
their names, e.g.:
TOCSearchItem, TOCSearchModelPrivate

In the CMakeLists.txt I added
   ui/tocsearch.cpp
   ui/tocsearchmodel.cpp
where toc.cpp is.

I also added necessary #include directives in the files where I want to use
new classes.

I created the tocsearch.moc and tocsearchmodel.moc files from toc.moc and
tocmodel.moc files.

These errors I get while running `make`:

Some help?
