java - Autofilter in apache POI range not working -


does know wrong following filter trying set report generated apache poi?

i'm using code:

sheet.setautofilter(cellrangeaddress.valueof("a4:a6"));

to result:

filters applied

however, when click arrow filter results value "average" possible result in dropdown list.

filter list

is there i'm missing here?

simply add empty row between data area , footer row. data area can limited empty rows , columns/header.

although you've selected a4:a6, a4 marked autofilter ... i'm not sure, think, can achieve horizontal autofilter via vba. setautofilter should a4:b4, mark header , not data area.

(tested poi 3.9, libre office 4.0)

import java.io.*; import org.apache.poi.hssf.usermodel.*; import org.apache.poi.ss.util.*;  public class autofilter {     public static void main(string[] args) throws exception {         hssfworkbook wb = new hssfworkbook();         hssfsheet sheet = wb.createsheet();         sheet.createrow(3).createcell(0).setcellvalue("protocol number");         sheet.createrow(4).createcell(0).setcellvalue("demonnumber1");         sheet.createrow(5).createcell(0).setcellvalue("demonnumber2");         sheet.createrow(6).setzeroheight(true);         sheet.createrow(7).createcell(0).setcellvalue("average");         sheet.setautofilter(cellrangeaddress.valueof("a4:b4"));         fileoutputstream fos = new fileoutputstream("autofilter.xls");         wb.write(fos);         fos.close();     } }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
