i'm trying develope application creates flex table dynamically database jdbc. want implement 2 methods, 1 update row values , 1 delete current row inserting 2 buttons per row. problem can't current row values.

here picture

fishtable method creates flextable

public void fishtable(){     if(service == null){         service = gwt.create(service.class);     }      service.getfishes(fishtablecallback); }

asynccallback fishtablecallback = new asynccallback(){

    @override     public void onfailure(throwable caught) {         string details = caught.getmessage();          system.out.println(details);     }      @override     public void onsuccess(fishtable result) {          table.removeallrows();                   tablepanel.clear();          table.settext(0, 0, "id");         table.settext(0, 1, "fish");         table.settext(0, 2, "price");         table.setcellpadding(6);         table.getcellformatter().addstylename(0, 0, "header1_3");         table.getcellformatter().addstylename(0, 1, "header2");         table.getcellformatter().addstylename(0, 2, "header1_3");          tablepanel.add(table);          (int = 0; < result.getidarray().length; i++) {              button updatebtn = new button("update");             button deletebtn = new button("delete");              id = new textbox();             id.settext(result.getidarray()[i]);             id.addstylename("fishid");             id.setreadonly(true);              name = new textbox();             name.settext(result.getnamearray()[i]);              price = new textbox();             price.settext(result.getpricearray()[i]);             price.addstylename("fishid");               int row = table.getrowcount();              table.setwidget(row, 0, id);             table.setwidget(row, 1, name);             table.setwidget(row, 2, price);             table.setwidget(row, 3, updatebtn);             table.setwidget(row, 4, deletebtn);               updatebtn.addclickhandler(new clickhandler() {                  @override                 public void onclick(clickevent event) {                      updatefish(id.gettext() , name.gettext() , price.gettext());                  }             });              deletebtn.addclickhandler(new clickhandler() {                  @override                 public void onclick(clickevent event) {                      index = table.getcellforevent(event).getrowindex()-1;                                             deletefish(table.gettext(index, 0));                  }             });         }      }   };

code inside updatebtn handler doesn't work, takes values last row. tried index = table.getcellforevent(event).getrowindex()-1 current row can't value of column 0 inside updatebtn handler. want send these values database. how values row click these buttons?

updatefish , deletefish methods:

public void deletefish(string id){     if(service == null){         service = gwt.create(service.class);     }      service.deletefish(id, deletefishcallback); }  public void updatefish(string fishid , string fishname , string fishprice){     if(service == null){         service = gwt.create(service.class);     }      service.updatefish(fishid , fishname , fishprice , updatefishcallback); }  asynccallback<deletefish> deletefishcallback = new asynccallback<deletefish>() {      @override     public void onsuccess(deletefish result) {                   fishtable();     }      @override     public void onfailure(throwable caught) {         string details = caught.getmessage();          system.out.println(details);      } };  asynccallback<updatefish> updatefishcallback = new asynccallback<updatefish>() {      @override     public void onsuccess(updatefish result) {         fishtable();     }      @override     public void onfailure(throwable caught) {         string details = caught.getmessage();          system.out.println(details);      } };

replace

int row = table.getrowcount();

with

final int row = table.getrowcount();

and do

deletebtn.addclickhandler(new clickhandler() {      @override     public void onclick(clickevent event) {         textbox tb = (textbox) table.getwidget(row - 1, 0);         deletefish(tb.gettext());     } });

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
