The following code is what I'm woking on, hope it can help you:
protected void init() {
VerticalPanel container = new VerticalPanel();
initWidget(container);
int pageSize = 10;
CellTable<User> cellTable = new CellTable<User>(pageSize);
setColumns(cellTable);
setSelectionModel(cellTable);
setDataSize(cellTable);
int pageStart = 0;
loadData(pageStart, pageSize, cellTable);
SimplePager<User> pager = createPager(cellTable);
container.add(cellTable);
container.add(pager);
}
private SimplePager<User> createPager(final CellTable<User>
cellTable) {
SimplePager<User> pager = new SimplePager<User>(cellTable,
SimplePager.TextLocation.CENTER) {
public void onRangeOrSizeChanged(PagingListView<User>
listView) {
loadData(listView.getPageStart(),
listView.getPageSize(),
listView);
super.onRangeOrSizeChanged(listView);
}
};
return pager;
}
private void setColumns(CellTable<User> cellTable) {
cellTable.addColumn(new TextColumn<User>() {
@Override
public String getValue(User user) {
return user.getName();
}
}, new TextHeader("Name"));
cellTable.addColumn(new TextColumn<User>() {
@Override
public String getValue(User user) {
return user.getLocation();
}
}, new TextHeader("Location"));
}
private void setSelectionModel(CellTable<User> cellTable) {
final SingleSelectionModel<User> selectionModel = new
SingleSelectionModel<User>();
SelectionChangeHandler selectionHandler = new
SelectionChangeHandler() {
@Override
public void onSelectionChange(SelectionChangeEvent
event) {
User user = selectionModel.getSelectedObject();
Window.alert(user.getId() + ": " +
user.getName());
}
};
selectionModel.addSelectionChangeHandler(selectionHandler);
cellTable.setSelectionEnabled(true);
cellTable.setSelectionModel(selectionModel);
}
private void setDataSize(final PagingListView<User> cellTable) {
employeeRequest.countUsers(new AsyncCallback<Integer>() {
public void onFailure(Throwable caught) {
Window.alert("Request failure: " +
caught.getMessage());
}
public void onSuccess(Integer result) {
cellTable.setDataSize(result, true);
}
});
}
private void loadData(int start, int size,
final PagingListView<User> cellTable) {
employeeRequest.getUsers(start, size,
new AsyncCallback<PagingData<User>>() {
public void onFailure(Throwable caught)
{
Window.alert("Request failure:
" + caught.getMessage());
}
public void onSuccess(PagingData<User>
result) {
cellTable.setData(result.getStart(),
result.getLength(), result.getValues());
}
});
}
