There is a need for a clickable ToC for navigating in bigger DocBook documents. The "Document structure" CSS seems to be fine for this purpose, but it is rather problematic to use for this because of GUI-related problems. Basically, you have to go trough this hassle for a simple ToC-based jumping:
1. View -> Add...-> bottom (or top) set to "Document structure". This must be repeated once per opening the document. 2. Enlarge the height of the bottom view by dragging its border. 3. Double-click on the desired ToC line. 4. Decrease the height of the bottom view by dragging its border (you don't want the ToC to take any vertical space from the main view when you don't "navigate"). Regarding some tricks involved in this process: - In 3. if you just click instead of double click, XXE may jumps back to the document start when the view is later resized in 4, hence spoiling what the whole thing was about. - The view has to be in top or the bottom slot, and must be enlarged vertically before the dobule-clicking, because the selected title will be at the bottom of the normal view, while you want it to be at the top of it. Now if the normal view is vertically small, and then after the double-clicking it is enlarged (4.) then the earlier bottom line will become the top line (try it to see why). So it is nor trivial nor convenient to do. Further notes: - Simply choosing the "Document structure" under View and then later restore it to "DocBook" is not good, as it is *very* slow for larger documents. Especially the switching back to "DocBook". - Putting the "Document structure" view at left or right and just always leaving it there is not good, because that CSS wastes horizontal space awfully (quite needlessly BTW -- this may could be improved), and thus its frame had to be so wide that no horizontal space is left for frame of the norma view on a 1280x1024 monitor. Not to mention that the selected title will be at the bottom of the normal view, and now the earlier explained vertical resizing trick can't be applied. - I know XXE can be customized and maybe this problem can be solved with that (I don't know), but a good *out-of-the-box* DocBook editing experience would be important. I'm sure most users just want to edit their DocBook (or DITA or XHTML) documents, not learn how to customize XXE. -- Best regards, Daniel Dekany
