\section intro_sec Introduction
kvsdemo is a minimal, but well-documented reference implementation of
a kviewshell plugin that can serve as a starting point for a
real-world implementation.
\section install_sec Usage
When kvsdemo is installed, the kviewshell program can open C++ source
files, i.e. files of mime type text/x-c++src. When such a file is
loaded, kviewshell shows 10 blank pages of A4 size.
\section content Content
Only the two classes that are absolutely necessary for a working
plugin are implemented. The only other file that is installed is a
desktop file, which tells kviewhshell to use the plugin.
- kvsdemo_multipage, an implementation of a kmultipage. In a real
application, this class would create and manage the GUI elements that
the plugin adds to the GUI of the kviewshell. This implementation adds
nothing, and does only the minimal initialization required..
- kvsdemo_renderer, an implementation of a documentRenderer. This
class is responsible for document loading and rendering.
- kvsdemo.desktop, the desktop entry file that tells KDE that kvsdemo
is a plugin for kviewshell that handles files of type
text/x-c++src. Without this file installed, the file dialog in
kviewshell would not show C++ source files, and the command line
"kvieshell test.cpp" would fail with an error dialog "No plugin for
text/x-c++src files installed".
*/
/*! \brief Well-documented minimal implementation of a KMultiPage
This class provides a well-documented reference implementation of a
KMultiPage, suitable as a starting point for a real-world
implementation. In a real application, this class would contain the
GUI elements that the plugin adds to the GUI of the kviewshell. Our
implementation adds nothing, and does only the minimal initialization
required.
