Shouldn't we have an enum an nice graphic comboboxes like for the other line properties? (even if we start by implementing only single and double lines, you can already argue: how much spacing between the two lines? For instance, if the basic line width is "lw", it may be useful to have: line(lw), space(lw), line(lw) but also line(lw), space(lw/2), line(lw) and line(lw), space(lw*2), line(lw) or foreground(lw), background(lw), foreground(lw) and foreground(lw), background(lw*2), foreground(lw) this would be a must with foreground=orange, background=yellow, to sketch a quick map to a destination which includes motorways At least, SVG is mute on this topic.It's ofcourse better to have the implementation more flexible, but I'm actually just searching for a double-line and hope to have something working in a decent timeschedule.
Hence my suggestion: make it a two-value ENUM (single or double-with-whatever-double-definition-you-need). It'll be easier to extend later in an upwards-compatible way. I sure don't want to scare you away though... do what you feel up to, the first patch is always free ;-)
It is on the "Standard - Line" that I want to achieve the double-line feature. But even when I clear the line_draw() function from dia, the "Standard - Line" still shows. When I double-click on that line, I get the properties for it (and it sais "Properties: Standard - Line") so I'm pretty sure I'm working with the correct object :)
Hmmm. Are we talking about the right function?
Look at object/standard/line.c; the structure line_ops says that the
DrawFunc is line_draw.
Try this patch:

works for me.
