Member Function Documentation

void gui2::circle_shape::draw ( surface canvas,
SDL_Renderer *  renderer,
wfl::map_formula_callable variables 
)
overridevirtual

Implement shape::draw().

Todo:
formulas are now recalculated every draw cycle which is a bit silly unless there has been a resize. So to optimize we should use an extra flag or do the calculation in a separate routine.

Implements gui2::canvas::shape.
