0001 KstDataSource Plugins
0002 ---------------------
0003
0004 The purpose of a KstDataSource plugin is to provide an implementation of the
0005 virtual class "KstDataSource". By default this class does nothing, which means
0006 that there is no direct way to load external data into Kst. Such a plugin
0007 provides three symbols:
0008
0009 extern "C" {
0010 // Create a data source.
0011 KstDataSource *create_<libname>(const QString& filename, const QString& type);
0012
0013 // Does this plugin understand the file indicated by the argument?
0014 bool understands_<libname>(const QString& filename);
0015
0016 // Which types of data does this plugin provide a data source for?
0017 QStringList provides_<libname>();
0018 }
0019
0020 Generally you will have to create one or more derived classes of KstDataSource
0021 which implement your I/O system.
0022
0023 Along with the shared object, you must also create a desktop file:
0024
0025 => kstdata_myplugin.desktop
0026

0039 You can find a template datasource plugin in kst/datasources/template/. It
0040 includes a proper Makefile.am, source files, and a desktop service file.
