Thanks for swift reply, Uli
The function to draw is:
colors for bg and fg are taken from array
function sep(fg,bg)
sp = wibox.widget.base.make_widget()
sp.fit = function(mycross, width, height)
local size = math.min(width, height)
return size/2, size
end
sp.draw = function(sp, wibox, cr,width, height)
r,g,b,a = hexadecimal_to_rgba_percent(fg)
cr:move_to(width,0)
cr:line_to(0, height)
cr:line_to(width,height)
cr:close_path()
cr:set_line_width(0)
cr:set_source_rgba(r,g,b,a)
cr:fill()
if string.match(bg,"#%w+")
then
r,g,b,a = hexadecimal_to_rgba_percent(bg)
cr:move_to(0,0)
cr:line_to(width,0)
cr:line_to(0,height)
cr:close_path()
cr:set_line_width(3)
cr:set_source_rgba(r,g,b,a)
cr:fill()
else
r,g,b,a = hexadecimal_to_rgba_percent(fg)
cr:move_to(0,0)
cr:line_to(width,0)
cr:line_to(0,height)
cr:close_path()
cr:set_line_width(3)
cr:set_source_rgba(r,g,b,a)
cr:fill()
end
end
return sp
end
