c++ - C++ and wxWidgets - Rasterisation - line width and filling

Question

Is there a modification of Bresenhman (or any) algorithm to draw line with defined line width? I can only use DrawPoint(x,y) function. And second question: how to implement filling a figure (for example i draw a triangle and how to make a fill). Please help :)
