Using GQuery in GWT widgets

Question

I am using the GWT application widget library and want to validate the controls in the button click event.The code I am writing

 GQuery input = $(e).filter("input[type='password']").widgets();

but its is giving me compile time error.Please tell me or refer me any tutorial for validating the widget library controls.

What kind of error do you get? – Peter Knego May 27 '11 at 05:08 — Peter Knego, May 27 '11 at 05:08

the widgets() method returns a list of widget and not a GQuery object

List<Widget> myPasswordInputs = $(e).filter("input[type='password']").widgets();

If you are only one input of type password you can maybe use directly widget() method :

PasswordTextBox myPasswordInput = $(e).filter("input[type='password']").widget();

Question: are you sure of your '$(e).filter("input[type='password']")' ? Because it means : "Create a GQuery object containing my element 'e' and keep it only if 'e' is an input of type password"

If you want to retrieve all password inputs present within an element e, you have to use :

List<Widget> myPasswordInputs = $("input[type='password']",e).widgets();

Hi Julien, There is no method as widget() or widgets that I am able to use, as this methods when I am writing giving me compile time error.Can you please suggest me where I can get the tutorial accessing my controls such as TextBox,label of com.google.gwt.user.client.ui.* package in GQuery.Any help from your side would really help me to complete my assignment.Thanks, Amandeep – Amandeep Singh May 27 '11 at 09:19
If you don't have a widgets() or widget() method, it is because you'are still using an old snapshot jar. Take the last stable should resolve your problems ! – jdramaix May 27 '11 at 10:43
this part of the gwtquery user guide can help you : http://code.google.com/p/gwtquery/wiki/GettingStarted#Manipulating_your_widgets – jdramaix May 27 '11 at 10:44

Try:

GQuery input = GQuery.$(e).filter("input[type='password']").widgets();

You need to do a static import to use $ directly:

import static com.google.gwt.query.client.GQuery.*;
import static com.google.gwt.query.client.css.CSS.*;
