plugin design problem

Show all headers | View raw

Hello,
i would like store a single plugin for every dll.
All plugin have a same interface.

For example suppose that every plugin (dll) have two C style function:
void mousePressed(int x, int y, OpenglContex * context)
void mouseMove(int x, int y, OpenglContex * context)

I would like remap c function extract from every dll on different class Plugin1 and Plugin2

class Plugin
{
public:
	Plugin() {};
	virtual void mousePressEvent(GLWidget* widget, QMouseEvent *event)=0;
	virtual void mouseMoveEvent(GLWidget* widget, QMouseEvent *event)=0;
....
};

and other subclass as

class Plugin1: public Plugin
{
// remap on dll 1
}

class Plugin2: public Plugin
{
// remap on dll2
}

Any idea how to solve my problem?
It's possibile declare function pointer in the Plugin1 or Plugin2 class and 
call them from method?
