True Oscar thx for helping in this discussion btw :O)

Its just that i want to draw a normal line (so no line-shape-thingy) on myVenster (=my map) and for that i need the coordinates of teh visualisation of myVenster (?)

SO I want my project-coordinate turned into a visualisation-coordinate.....

or am i thinking to complex?



as i said i just want to draw a line on the map consisting of several coordinates and the user get an idea of the total length of this line.....

so with every click i store the coordinate in an array

and calculate the length towards the former position

but i also want to draw the lines between the positions in this array on screen......

(i must admit that i never tried to do it with lines in a maplayer and deleting this layer when its not needed anymore..... , but still i want to learn to draw llines on a screen without using layers....)
