• NCurses, scrolling of multiline items, "current item" pointer and "selected items"

  - by mjf

  I am looking for hints/ideas for the best (most effective) way on how to scroll multi-line items as well as emphasizing of the "current item" and "selected items" such as: 1 FOO ITEM 1 Foo sub-item 2 Foo sub-item 3 Foo sub-item 2 BAR ITEM 1 Bar sub-item 3 BAZ ITEM 1 Baz sub-item 2 Baz sub-item 4 RAB ITEM 5 ZZZ ITEM 1 Zzz sub-item 2 Zzz sub-item 3 Zzz sub-item 4 Zzz sub-item using NCurses (some combination of windows, sub-windows, pads, copywin? Uff! In fact, the lines could exceed the stdscr's width so that possibility to scroll left/right would be also nice - pads?)... The whole items (including the sub-items) are supposed to be emphasized as full-width window/pad areas. The "current item" (including it's set of lines) should be emphasized (i.e. using A_BOLD), selected set of items of choice (including the set of lines for each the selected item) should be emphasized in another way (i.e. using A_REVERSE). What would you choose to cope with it the most effective NCurses way? (The less redrawals/refreshes the better and terminal is supposed to have the ability to change it's size - such as XTerm running under "floating window" management.) Thank you for your ideas (or perhaps some piece of code where something similar is already solved - I was not able to find anything helpful on the Internet. I mean I am not going to copy/paste foreign code but programming NCurses properly is still somehow difficult to me). P.S.: Would you suggest to "smooth-scroll" +1/-1 screen line or rather "jump-scroll" +lines/-lines of the items? (I personally prefer the latter one.) Sincerely, -- mjf

• ExceptionHandling with Spring 3

  - by mjf

  I have this controller: @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; The excel wiew opens actually a ExcelViewer, which is build in method protected void buildExcelDocument(Map<String, Object> map, WritableWorkbook ww, HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception { Class.writecontent Class.writeMoreContent Called methods write content to the Excel sheet and they can throw e.g biffException. How can I show a certain error page when Exception is occured? I tried this @Controller public class ExcelController { @ExceptionHandler(BiffException.class) public String handleException(BiffException ex) { return "fail"; } @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; } } But I'm getting the server's error message about Exceptions. Maybe a bean definition missing?
