Well, aligning size should not change the unchangeable... it's one of those things that are not critical (you can get by in most cases with some work with grids), but should be there at some point. >> An arrow select widget could have these choices: >> >> | | V ^ V >> | | | | | >> | V V V | >> >> A pop-up option box could then allow more control over arrow head >> styles. > > Well, i rather though it would be just a pop-up selection of arrow > types, and then the line objects has two of these, one for each end. So you'd have to manually add the arrows on each line? Or should this be part of the options box (both default and individual) for lines? >>>> Splines. >>> They exist in the back-end of the program.

I've started working on it (copying from orth_conn). Now I don't know the first thing about bezier (so I'm very happy the drawing function is there:). I notice that you require 4+3n points, is that because of the specific method you use? Xfig has two splines with no such limit (at least not visibly). But I guess I have to dig into it to figure out a bounding box. We should also have a generic polyline, I think. That should be even easier than bezier, possibly they should be derived from some common class. There is a common element of making new midpoints that they should share, though I'd like to find a better way than Xfig's. >>>> A limit on the width of a text 'box', with word wrap.

Except for picture inclusion, I think dia is more usable than xfig for this. But this is a low-priority thing.

If we can export to xfig format, there are several converters to other formats available. >> BTW, it is remarkably stable for such a low version number.

But at least I got a good base to work from here. It's fun connecting lines at their midpoints and moving them around. Looks almost 3D:) -Lars -- Lars R.
