xfig implemented a quite nice spline model known as X-Splines, that makes providing a nice UI for editing splines dead easy, then completely futzed up the interface. Oh well. Create your spline. Then select "Edit" in the left panel. Now click on a point with the right mouse button. This brings up a dialog where you get a slider to alter the approach of the line to the control point. My old project (I wouldn't recommend using it btw) had a much nicer way of handling x splines: create the spline, select it with the main editing tool, press space to edit points, then hold down control and click-drag on a point to edit the value of the point. When I wrote that, xfig didn't even have a slider, you had to type a value from -1.0 to +1.0 ... http://figurine.sf.net/ if you're bored :) regards john -- Khendon's Law: If the same point is made twice by the same person, the thread is over.
