i create the chart in on

void createChart() { Chart = new Chart() .setChartTitleText(currentChart.getName()); Chart.getYAxis().setAxisTitleText(currentChart.getyLabel()); Chart.addSeries(serie); } panelCharts.add(Chart); chartAnzahl=result.entrySet().size();//get the items of elements of elements of the list } } public void onSuccess(List<Group> result) { // for each group, add a list item for (Group g : result) { list.addItem(g.getName()+" ("+chartcount+")", String.valueOf(g.getId())); } //sum of all charts in the list total list.addItem("All "+"("+chartcount+")", String.valueOf(0)); } }; // call the RPC service for getting the list of groups for the current group rpcService.getGroups(currentID, callback);

i can't understand how to call this chartAnzahl in the onSuccess method, to show the count of this item elements within the elements of the list

thank you all for answering, with the nested loop for for(Group p: list) { l.add(p.getName()+ "("+number+")",p.getId());} how can i add the second loop hier? it means it must loop for each element in p, can you please provide me some sample code?

i need to get the count of the items elements in each item of the list. For example i have one group list in this list are 5 elements, and on each elements there are also some other items. I need to get these count of the items on each elements list to show them nearby elements name in brackets like:

element1 (5) element2 (7) ...
I have a list of the group, then i add elements with the name and id to this list, like:

for(Group p: list) { l.add(p.getName(),p.getId());}
how can i get the count of each item elements that contains in p? Any suggestions

I have one list of Group

Group -Group1 -Group2 -Group3 -Group4 -...
each group item has its own elements

Group -Group1 -el1 -el2 -el3 -el4 -... -Group2 -el1 -el2 -el3 -el4 -Group3 -Group4 -...
i want to get the count of the last tree elements to show on the Group1 (4) for example

i have two methods in one of them i call the

number=r.entrySet().size
and get the number of elements that i want but on console, if i call this variable in the second method is it null,

for(Group p: list) { l.add(p.getName()+ "("+number+")",p.getId());}
how to call it in the second method, i defined it as static

private static int number;

i am using gwt highcharts and i want to get client timezone calling jsni method from jstimezoneDetect in my client java code:

i bind it to my html:

<script type="text/javascript" src="js/jstz-1.0.4.min.js"></script>
and call this on client:

static native String getClientTZ() /*-{ var tz = jstz.determine(); return tz.name(); }-*/;
then i call it on page loading:

private String clientTimeZone; pulic UI{ clientTimeZone=getClientTZ(); ....
but i'm gettin these error:

com.google.gwt.core.client.JavaScriptException: (ReferenceError) @UI::getClientTZ()([]): 'jstz' is undefined

please any suggetions, what i am doing wrong?

thank you for answer, i want to set first value for one function as start time at 18 pm clock and the end to 6 am clock of the next day and so on for one week as a Number, so i can highlaight the night time from 1st day to another how it can be done?

HI, can you please help me with time converting into one month, for example 24*3600*1000 is 1 day and 6*3600*1000 is each 6 hour what will be then it for one month and one week? ((24*3600*1000)*30) for 1 month or 5760*43200*2592000 for one month and for one week 720*43200*2592000 or 168*3600*1000 ?

i want get the unix timestamp dynamish threw the query in java from db, how can i dynamish convert from oracle datetime to unix timestamp: for example i make this :

select * from table where timestamp>=to_date('1970-01-01','YYYY-MM-DD') + numtodsinterval( 1404432000,'SECOND') and timestamp<= to_date('1970-01-01','YYYY-MM-DD') + numtodsinterval( 1404604800,'SECOND') and the data is for 1404604800 is for 6.Juli 2014 and 1404432000 for 4.Juli 2014, how can i change the query to get the values dynamisch for the data such as 1404432000 and 1404604800?

if i implementlong l=lowB.getTime()/1000; and then write it instead of 1404432000 in query such select * from table where timestamp>=to_date('1970-01-01','YYYY-MM-DD') + numtodsinterval("+l+","+"'SECOND')"+ and timestamp<= to_date('1970-01-01','YYYY-MM-DD') + numtodsinterval( 1404604800,'SECOND') and for the second datatime for example get the earlier 7 days, how to do it?is it wrong? Any suggestions?

on each object i get the list of elements on my gwt ui that the data that i populate ui with, and i get only on the last object the list of elements in ui, but want to get it for each object object, can you suggest me what am doing wrong? I add all the objects from first and second callbacks into panel at the end, must i do it in another place? (first asynccallback for the object and the second for the element into this objects)

void show(int last) { AsyncCallback<List<C>> callback = new AsyncCallback<List<C>>() { public void onFailure(Throwable caught) { } public void onSuccess(List<C> result) { for (C c : result) { first = new Chart() .setType(Series.Type.SPLINE) .setSizeToMatchContainer() .setLegend( new Legend() .setLayout(Legend.Layout.VERTICAL) .setAlign(Legend.Align.RIGHT) .setVerticalAlign( Legend.VerticalAlign.TOP) .setX(-10).setY(100) .setBorderWidth(0)) .setZoomType(Chart.ZoomType.X_AND_Y); first.setStyleName("chart"); Series series = first .createSeries() .setName("Summer") .setPoints( new Number[] { 7.0, 6.9, 9.5, 14.5, 18.4, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }); first.setCredits(new Credits().setEnabled(false)); first.addSeries(series); first.setChartTitleText(c.getName()); AsyncCallback<List<M>> callbackA = new AsyncCallback<List<M>>() { public void onFailure(Throwable caught) { } public void onSuccess(List<M> result) { for (M m : result) { Series serie = firstChart.createSeries().setName( m.getDName()); first.addSeries(serie); } } }; rpcService.getKList(c.getP(), callbackA); panel.add(first); } } }; rpcService.getList(last, callback)

yes, i did it like in sample that i posted, and the first asynccallback is work and i can get the data from db, but the second asynccallback doesn't do anything

can you please suggest me, how can i call inside of first AsyncCallback after calling on Success, the second AsyncCyllback? i use gwt rpc and load my data into ui, and after calling this first AsyncCallback on Success method i must call another AsyncCallback that execute the next part of the first AsyncCallback and load data from db into ui:

void show(int last) { AsyncCallback<List<C>> callback = new AsyncCallback<List<C>>() { public void onFailure(Throwable caught) { } public void onSuccess(List<C> result) { panelCharts.clear(); for (C c : result) { first = new Chart() .setType(Series.Type.SPLINE) .setSizeToMatchContainer() .setLegend( new Legend() .setLayout(Legend.Layout.VERTICAL) .setAlign(Legend.Align.RIGHT) .setVerticalAlign( Legend.VerticalAlign.TOP) .setX(-10).setY(100) .setBorderWidth(0)) .setZoomType(Chart.ZoomType.X_AND_Y); first.setStyleName("chart"); Series series = first .createSeries() .setName("Summer") .setPoints( new Number[] { 7.0, 6.9, 9.5, 14.5, 18.4, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6 }); first.setCredits(new Credits().setEnabled(false)); first.addSeries(series); first.setChartTitleText(c.getName()); AsyncCallback<List<M>> callbackA = new AsyncCallback<List<M>>() { public void onFailure(Throwable caught) { } public void onSuccess(List<M> result) { for (M m : result) { Series serie = firstChart.createSeries().setName( m.getDName()); first.addSeries(serie); } } }; rpcService.getKList(ID, callbackA); panelCharts.add(first); } } }; rpcService.getList(last, callback);

i get no exceptions, that second asynccallback doesnt work, cant load the data

can you please suggest me, how can i call inside of first AsyncCallback after calling on Success, the second AsyncCyllback? i use gwt rpc and load my data into ui, and after calling this first AsyncCallback on Success method i must call another AsyncCallback that execute the next part of the first AsyncCallback

thank you for answering, but i can't understand what did you ment
