Hi, everyone.
I have a simple (or complex) c++ question.
The below source code do not be compiled and make
errors.
I really don't know why. Maybe I'm too foolish
-_-;
I'll wating for your answering. Thanks so much.
/****** begin of source ******/
class Widget
{
protected:
void draw() {}
int _i;
};
class Button : public Widget
{
protected:
void draw()
{
((Widget*)this)->_i++;
((Widget*)this)->draw();
}
};
void main() {}
/******* end of source ********/
I think that it's a compiler (internal) problem.
I compiled it with VC++ and GCC but All failed.
I think that the problem comes from accessing of type-casted
'this' pointer
But I don't know exactly.
Happy new year. |
