| Whenever I compile any wx windows code that I've written I get a missing
vtable error as such, code first, error second:
------------------------------------------------------------------------

{
public:

~wxDisp();
void setpixel(aint x, aint y, acolor c);
acolor getpixel(aint x, aint y);
void setrange(afloat nmin, afloat nmax);
//vector<acolor> pixels;
afloat min, max;
private:
DECLARE_EVENT_TABLE()
};
