Hi Noor,
Heres an example of a Celltable (using a DataProvider):
public class TestTable implements EntryPoint {
private GreetingServiceAsync gService;
private CellTable<MyStat> table;
/**
* This is the entry point method.
*/
public void onModuleLoad() {
// Create a CellTable.
table = new CellTable<MyStat>();
// Create name column.
gService = GWT.create(GreetingService.class);
TextColumn<MyStat> mIdColumn = new TextColumn<MyStat>() {
public String getValue(MyStat stat) {
return ""+stat.getId();
}
};
// Create address column.
Column<MyStat, String> machIdColumn = new Column<MyStat,
String>(new EditTextCell()) {
@Override
public String getValue(MyStat stat) {
return stat.getMachineId();
}
};
machIdColumn.setFieldUpdater(new FieldUpdater<MyStat, String>()
{
@Override
public void update(int index, MyStat object, String
value) {
object.setMachineId(value);
Window.alert(value);
}
});
TextColumn<MyStat> msisdnColumn = new TextColumn<MyStat>() {
public String getValue(MyStat stat) {
return stat.getMsisdn();
}
};
Column<MyStat, String> bCol = new Column<MyStat, String>(new
ButtonCell()){
@Override
public String getValue(MyStat myDto) {
return "OK";
}
};
bCol.setFieldUpdater(new FieldUpdater<MyStat, String>() {
@Override
public void update(int index, MyStat object, String
value) {
Window.alert("testing");
}
});
// SelectionCell.
final List<String> options = new ArrayList<String>();
options.add("Opt1");
options.add("Opt2");
options.add("Opt3");
options.add("Opt4");
options.add("Opt5");
options.add("Opt6");
options.add("Opt7");
options.add("Opt8");
Column<MyStat, String> colMe = new Column<MyStat, String>(new
SelectionCell(options)) {
@Override
public String getValue(MyStat object) {
return options.get(object.getOptId());
}
};
colMe.setFieldUpdater(new FieldUpdater<MyStat, String>() {
@Override
public void update(int index, MyStat object, String
value) {
int i = 0;
for (String category : options) {
if (category.equals(value)) {
object.setOptId(i);
break;
}
i++;
}
}
});
// Create a data provider.
MyDataProvider dataProvider = new MyDataProvider();
// Add the cellList to the dataProvider.
dataProvider.addDataDisplay(table);
// Add the columns.
table.addColumn(mIdColumn, "ID");
table.addColumn(machIdColumn, "MachineId");
table.addColumn(bCol, "Report");
table.addColumn(msisdnColumn, "Msisdn");
table.addColumn(colMe, "Country");
// Set the total row count. This isn't strictly necessary, but it
affects
// paging calculations, so its good habit to keep the row count
up to date.
table.setRowCount(100000, false);
NoSelectionModel<MyStat> selectionModel = new
NoSelectionModel<MyStat>();
table.setSelectionModel(selectionModel);
SimplePager pager = new SimplePager();
pager.setDisplay(table);
RootPanel.get().add(table);
RootPanel.get().add(pager);
}
class MyDataProvider extends AsyncDataProvider<MyStat> {
/**
* {...@link #onRangeChanged(HasData)} is called when the table
requests a new
* range of data. You can push data back to the displays using
* {...@link #updateRowData(int, List)}.
*/
@Override
protected void onRangeChanged(HasData<MyStat> display) {
// Get the new range.
final Range range = display.getVisibleRange();
/*
* Query the data asynchronously. If you are using a database,
you can
* make an RPC call here. We'll use a Timer to simulate a
delay.
*/
final int start = range.getStart();
int length = range.getLength();
System.out.println("Range: " + start + " <" + length + ">");
gService.getStats(start, length, new
AsyncCallback<ArrayList<MyStat>>() {
@Override
public void onSuccess(ArrayList<MyStat> result) {
updateRowData(start, result);
}
@Override
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
}
});
}
}
}
