\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".
