Hello, I'm pretty new to GWT
I have a problem trying to sort specific columns from a cell table, whcih
is populated from the DB, using RPC. Basically I'm trying to sort the
family name column alphabetically, and it's just not working. Table gets
fully populated, but sorting does not work.
Any ideas why ?
Thanks in advance
// Create the family name column.
final TextColumn<ContactInfo> familyNameColumn = new
TextColumn<ContactInfo>() {
@Override
public String getValue(ContactInfo object) {
return object.getFamilyName();
}
};
table.setColumnWidth(familyNameColumn, 20, Unit.PCT);
// Make the family name sortable
familyNameColumn.setSortable(true);
// Add the columns
table.addColumn(familyNameColumn, UserMenuConstants.FAMILY_NAME_COLUMN);
table.addColumn(familyAdministratorColumn,
UserMenuConstants.FAMILY_ADMINISTRATOR_COLUMN);
table.addColumn(apartmentNuberColumn,
UserMenuConstants.FAMILY_APARTMENT_NUMBER_COLUMN);
table.addColumn(emailColumn, UserMenuConstants.EMAIL_ADDRESS_COLUMN);
table.addColumn(phoneNumberColumn, UserMenuConstants.PHONE_NUMBER_COLUMN);
DBGetContactInfoAsync rpcService = (DBGetContactInfoAsync)
GWT.create(DBGetContactInfo.class);
ServiceDefTarget target = (ServiceDefTarget) rpcService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "DBGetContactInfoImpl";
target.setServiceEntryPoint(moduleRelativeURL);
rpcService.getContacts(new AsyncCallback<List<ContactInfo>>() {
@Override
public void onSuccess(List<ContactInfo> result) {
table.setRowCount(result.size());
ListDataProvider<ContactInfo> dataProvider = new
ListDataProvider<ContactInfo>();
dataProvider.addDataDisplay(table);
List<ContactInfo> list = dataProvider.getList();
for (ContactInfo contactInfo : result) {
list.add(contactInfo);
}
ListHandler<ContactInfo> listHandler = new
ListHandler<ContactInfo>(result);
listHandler.setComparator(familyNameColumn, new
Comparator<ContactInfo>() {
@Override
public int compare(ContactInfo o1, ContactInfo o2) {
return o1.getFamilyName().compareTo(o2.getFamilyName());
}
});
table.addColumnSortHandler(listHandler);
}
@Override
public void onFailure(Throwable caught) {
...
}
});
