How to avoid freezing with CellTable?
Hi everybody,
I'm creating a website with GWT. I want to add CellTable into my project.
The problem is that I have a lot of data to put into the tables. So, my
website freeze and show my table after 2-3 minutes.
I find on internet that multi-threads are impossible with GWT. So, what is
the solution? Even if the user have to wait 2-3 minutes, I want to avoid
the fact that it's freezing.
Any Ideas?
Thank you.
My code, maybe I can optimize it simply?
public void refreshTable(final ArrayListString arrListFilters, final
ArrayListString arrListAll, String url) {
// Get the CQ result
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
try {
Request response = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
}
public void onResponseReceived(Request request, Response response) {
final json json = JsonUtils.unsafeEval(response.getText());
int i = 0;
int j = 0;
int tot;
// If there are too many results
if (json.getResultslength() 1) {
tot = 1;
} else {
tot = json.getResultslength();
}
// Fill the list of rows
while (j tot) {
i = 1;
ListString rowTemp = new ArrayListString();
rowTemp.add(json.getDate(j));
// Get the data to get a price result for a specific
// customer query
arrListLnNb.add(json.getLineNb(j));
arrListId.add(json.getId(j));
arrListCqid.add(json.getCqid(j));
while (i arrListFilters.size()) {
rowTemp.add(json.getResults(j, arrListAll.indexOf(arrListFilters.get(i;
i = i + 1;
}
rowTemp.add();
rows.add(rowTemp);
j = j + 1;
}
// Provide rows to the table
table.setRowCount(rows.size(), true);
table.setRowData(0, rows);
final ListDataProviderListString provider = new
ListDataProviderListString(rows);
provider.addDataDisplay(table);
// Handler to sort the columns
ListListString list1 = provider.getList();
ListHandlerListString columnSortHandler = new
ListHandlerListString(list1);
i = 0;
while (i table.getColumnCount()) {
final int columnIndex = i;
columnSortHandler.setComparator(table.getColumn(i), new
ComparatorListString() {
public int compare(ListString o1, ListString o2) {
if (o1 == o2) {
return 0;
}
// Compare the name columns.
if (o1 != null) {
return (o2 != null) ? o1.get(columnIndex).compareTo(o2.get(columnIndex)) :
1;
}
return -1;
}
});
i = i + 1;
}
table.addColumnSortHandler(columnSortHandler);

Re: Get Data CellTable
Now I understand why you talk about refresh() or updateRowData(...). The
first method doesn't do anything for me and my provider dosen't know the
second method updateRowData. I don't find a solution on google.
This is a part of my code:
public ArrayListListString rows = new ArrayListListString();
ListDataProviderListString provider;
//...
*public widget *
// fill the rows
//add the IndexedColumn
table.setRowCount(rows.size(), true);
table.setRowData(0, rows);
provider = new ListDataProviderListString(rows);
provider.addDataDisplay(table);
//...
// Save handler
if (item.getText() == Save) {
int i=0;
provider.refresh();
while(itable.getRowCount()){
System.out.println(provider.getList().get(i)); // I can't see the changes
of the final user here!
i=i+1;
}
}
*IndexedColumn:*
// Method to add column dynamically to the table
class IndexedColumn extends ColumnListString, String {
private final int index;
public IndexedColumn(int index) {
super(new EditTextCell());
this.index = index;
}
@Override
public String getValue(ListString object) {
return object.get(this.index);
}
}
Can somebody help me please?
Thanks :)

Re: columnSortHandler on a Dynamic CellTable
Thanks for your answer.
I didn't know what to do, so I test with the 0th entry. I know that it is
not the solution.
In your answer, columnIndex is my i I guess? I can't get it, it must be
final.
I try to do that, but it doesn't work too:
i=0;
while(itable.getColumnCount()){
*final ColumnListString, ? column= table.getColumn(i);
*columnSortHandler.setComparator(*column*,new ComparatorListString() {
public int compare(ListString o1,ListString o2) {
if (o1 == o2) {
return 0;
}
if (o1 != null) {
*return (o2 != null) ?
o1.get(table.getColumnIndex(column))**.compareTo(o2.get(table.getColumnIndex(column)))
: 1;
*}
return -1;
}
});
i=i+1;
}
Le mercredi 24 avril 2013 16:24:36 UTC-4, Jens a écrit :
Why do you always compare the 0th entry? Shouldn't it match the column the
comparator is responsible for, e.g.
o1.get(columnIndex).compareTo(o2.get(columnIndex))?

Why do you always compare the 0th entry? Shouldn't it match the column
the comparator is responsible for, e.g.
o1.get(columnIndex).compareTo(o2.get(columnIndex))?

Re: Complex JSON and overlay types
Thank you for your answers.
- Thomas:
Yes, it works. But the problem is that I don't know John. It can be
anything else. For example the JSON can be: *{records: [{names:
{Cedric: [50, H, US], Jean: [50, H, US]}, style: TR}]} *or
{records: *[{names: {Blabla: [50, H, US]}, style: TR}]}. *To
get the lists, I have to get the names first. And I don't know how to do.
- Stefan:
I try to do that but I get *null *even for *bean.as().getStyle().* I don't
understand how this method can get the properties..
*interface Message {
ListPerson getRecords();
}*
*interface Person {
MapString, ListString getNames();
String getStyle();
}*
* // Declare the factory type
interface MyFactory extends AutoBeanFactory {
AutoBeanMessage message();
AutoBeanPerson person();
}*
*public class HelloWorld implements IsWidget,EntryPoint {
public Widget asWidget() {
String url=data.json;
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
url);
try {
Request response = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
// Code omitted for clarity
}*
* public void onResponseReceived(Request request, Response
response) {
MyFactory factory = GWT.create(MyFactory.class);
AutoBeanPerson bean = AutoBeanCodex.decode(factory,
Person.class, response.getText());
System.out.println(oui + bean.as().getNames());
*
* }*
* });
} catch (RequestException e) {
}
return null;
}*
*@Override
public void onModuleLoad() {
asWidget();
}

Does *this.records[0].names[John]* works? If so, there shouldn't be any
problem replacing the John with a method argument.

Decoding complex JSON
Hi everybody,
I want to read this kind of JSON with GWT:
{records: [{names: {John: [50, H, US], Jack: [50, H,
US]}, style: TR}]}
I use overlay for that.
If I use that, I get TR:
public final native String getStyle()
/*-{
return this.records[0].style;
}-*/;
So, it's work. Now I want to get John and the list 50,H,US. If I use that I
get null:
public final native String getNames(String i)
/*-{
return this.records[0].names[i];
}-*/;
For the same thing, I try to do that and I get no result: (json is the of
my class which is extended by JavaScriptObject)
public final native JsArrayjson getArray(String key) /*-{
return this[key] ? this[key] : new Array();
}-*/;
and
result.getArray(names).toString()
Have you any idea to do what I want?
Thank you in advance !

It looks like your array is defined at: records[0].names.John

Re: Complex JSON and overlay types
Thanks. I try it, but I don't undestand how does it works... Do you have
simple examples or tutorials?
I try to do it:
*interface Person {
Names getNames();
String getStyle();
}*
* interface Names {
// Other properties, as above
String getProp1();
String getProp2();
String getProp3();*
* }*
* // Declare the factory type
interface MyFactory extends AutoBeanFactory {
AutoBeanNames names();
AutoBeanPerson person();
}*
*public class HelloWorld implements IsWidget,EntryPoint {
public Widget asWidget() {
String url=data.json;
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
//builder.setHeader(Access-Control-Allow-Origin, *);
try {
Request response = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
// Code omitted for clarity
}*
* public void onResponseReceived(Request request, Response
response) {
MyFactory factory = GWT.create(MyFactory.class);
AutoBeanPerson bean = AutoBeanCodex.decode(factory,
Person.class, response.getText());
System.out.println(oui + bean.as().getNames());
*
* }*
* });
} catch (RequestException e) {
}
return null;
}*
*@Override
public void onModuleLoad() {
asWidget();
}
}*
I get *null*. What do you think?
*I'm still interested by a method with overlay type (= Javascript)*, just
to get Jack and John in *{records: [{names: {John: [50, H,
US], Jack: [50, H, US]}, style: TR}]}.*

Complex JSON Overlay
Hi all,
I try to use overlay type on this kind of JSON:
{records: [{names: {John: [50, H, US], Jack: [40, H, EN]},
style: TR}]}
So, to get the value of style, I do that and it works:
public final native String getStyle()
/*-{
return this.records[0].style;
}-*/;
Now I want to get the values of names. I do that and what I get is always*
null*.
public final native String getNames(final int i)
/*-{
return this.records[0].names[i];
}-*/;
Why? Is it the good way to get the names and their properties? (like [50,
H, US])
Thank you in advance :)
