Detailed Description

Abstract base class for simplified access to UI plugins for graph widget.

Constructor & Destructor Documentation

YGraphPlugin::YGraphPlugin ( const char * pluginLibBaseName )

inlineprotected

Constructor: Load the specified plugin library from the standard UI plugin directory (/usr/lib/yui/).

virtual YGraphPlugin::~YGraphPlugin ( )

inlineprotectedvirtual

Destructor. Calls dlclose() which will unload the plugin library if it is no longer used, i.e. if the reference count dlopen() uses reaches 0.

virtual YGraph * YGraphPlugin::createGraph	(	YWidget *	parent,
		const std::string &	filename,
		const std::string &	layoutAlgorithm )

pure virtual

Create a graph widget. Derived classes need to implement this.

This might return 0 if the plugin lib could not be loaded or if the appropriate symbol could not be located in the plugin lib.
