Draw event for all objects with same name

[Stancho]

Hey guys. So i have an object that draws shadows for all my other objects. I'm at the point where i want to draw_ellipse for my trees. so i write
draw_ellipse_colour(obj_tree.x-34,obj_tree.y-27,obj_tree.x+39,obj_tree.y+10,c_dkgray,c_dkgray,false);
but only one of my trees gets the ellipse drawn, what am i missing to have this ellipse drawn on all my obj_tree?

thanks guys.

The easiest way is probably 'with' statement

with(obj_tree)
    {
    draw_ellipse_colour(x-34,y-27,x+39,y+10,c_dkgray,c_dkgray,false);
    }
