Can anyone give me some pointers as to how the RISC OS front-end's plotter code is supposed to be used?
Specifically, the coordinate system has got me a bit puzzled. Am I correct in thinking that a redraw loop should set ro_plot_origin_x and _y to the window origin, and then work entirely in window coordinates thereafter? And does that mean that when things like treeview's tree_draw() ask for x and y coordinates, they do so relative to the window origin and not the desktop graphics origin? -- Steve Fryatt - Leeds, England http://www.stevefryatt.org.uk/
