Abstract base class for simplified access to UI plugins for graph widget.
YGraphPlugin::YGraphPlugin | ( | const char * | pluginLibBaseName | ) | [inline, protected] |
Constructor: Load the specified plugin library from the standard UI plugin directory (/usr/lib/YaST2/plugin).
virtual YGraphPlugin::~YGraphPlugin | ( | ) | [inline, protected, virtual] |
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 string & | filename, | ||
const 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.
