here data text file:

21/08/12#ese-6329#pv/5732#30 27/08/12#pea-4567#pv/5732#3@ 11/09/12#ese-5577#xk/8536#2 14/09/12#pnw-1235#hy/7195#2@

and code form main method:

file orderdata = new file("purchaseorderdata.txt");             scanner datascan = new scanner(orderdata);  while(datascan.hasnextline()) {     string linedata = datascan.nextline();      scanner linescan = new scanner(linedata);     linescan.usedelimiter("#");      string date = linescan.next(); // line 259     string id = linescan.next();     string code = linescan.next();      string quantityplus = linescan.next();      if(!quantityplus.contains("@"))         management.addnewpurchaseorder(date, id, code,                                      integer.parseint(quantityplus)); // line 267     else     {         quantityplus = quantityplus.replace("@", "");         management.addnewpurchaseorder(date, id, code,                                     integer.parseint(quantityplus));         management.startnewmonth();     }

on first instance of 

management.addnewpurchaseorder(date, id, code, integer.parseint(quantityplus));

i exception:

java.lang.numberformatexception: input string: "2 "     @ java.lang.numberformatexception.forinputstring(numberformatexception.java:65)     @ java.lang.integer.parseint(integer.java:580)     @ java.lang.integer.parseint(integer.java:615)     @ assignment2.maintest.main(maintest.java:267)

if do:

string quantityplus = linescan.next(); quantityplus = quantityplus.replace(" ", "");

i following:

java.util.nosuchelementexception java.util.nosuchelementexception     @ java.util.scanner.throwfor(scanner.java:862)     @ java.util.scanner.next(scanner.java:1371)     @ assignment2.maintest.main(maintest.java:259)

maintest.java:259 - string date = linescan.next();

i've tried use nextint() well, result same. wrong there?

thanks lot!

maintest.java:259 - string date = linescan.next(); should check before if line not empty might why scanner throwing exception

i know it's possible change color of rubber band rectangle way: qrubberband rubberband = new qrubberband(qrubberband::rectangle, this); qpalette pal; pal.setbrush(qpalette::highlight, qbrush(qt::white)); rubberband->setpalette(pal); but here way achieve rubber band, rendered qgraphicsview when rubberbanddrag mode active? or in "global scope"? i'm sorry wrote question, i've looked solution long time, , nothing. few minutes after asking, found solution setting stylesheet. i'm sharing it. just go designer of qt creator, click on canvas (qgraphicsview). in "qwidget" part find "stylesheet", edit it, , put like: selection-background-color: rgba(255, 255, 255, 128); that's :-). thanks.
