Non-filled rect?

For OpenGL,
set drawing mode to outline of points: glPolygonMode(GL_FRONT_AND_BACK, GL_POINT)
set drawing mode to outline of lines: glPolygonMode(GL_FRONT_AND_BACK, GL_LINE)
set drawing mode to filled: glPolygonMode(GL_FRONT_AND_BACK, GL_FILL)
EDIT: little function here

Const DRAW_POINT:Int = GL_POINT
Const DRAW_LINE:Int = GL_LINE
Const DRAW_FILL:Int = GL_FILL

Function SetDrawMode(mode:Int)
    glPolygonMode(GL_FRONT_AND_BACK, mode)
EndFunction
