How to create composite widget in SmartGWT

[ganmo]

Hello,

I want to separate codes in my SmartGWT project so I don't need to have huge chunk of code in the EntryPoint. Anyway in GWT I would just need to create a new class which extends the Composite class, and then I just need to create an instance so i can add it into the RootPanel. However that doesn't work with GWT. So i wonder how it should be done, or what's the best practice for separating codes in SmartGWT? An example code would be helpful.

After some googling I found an old thread here on this forum with the same question. So I made a try to see if it works. However it doesn't work and I get error. Below is the code which produce the error.

package com.project.client;

import com.google.gwt.core.client.EntryPoint;
import com.project.screen.LoginScreen;

public class Project implements EntryPoint {

	public void onModuleLoad() {

	LoginScreen login = new LoginScreen();
	login.draw();

	}
}

package com.project.screen;

import com.smartgwt.client.widgets.form.DynamicForm;
import com.smartgwt.client.widgets.form.fields.HeaderItem;
import com.smartgwt.client.widgets.form.fields.PasswordItem;
import com.smartgwt.client.widgets.layout.VLayout;

public class LoginScreen extends VLayout {

	public LoginScreen() {

		DynamicForm form = new DynamicForm();
		HeaderItem header = new HeaderItem();
		header.setDefaultValue("Login");

		PasswordItem passwordItem = new PasswordItem();
		passwordItem.setName("password");

		form.setFields(header, passwordItem);
		form.setValue("userName", "bsmith");
		form.setValue("firstName", "Bob");
		form.setValue("lastName", "Smith");
		form.setValue("email", "bob@.com");
		form.setValue("password", "sekrit");

		addMember(form);
	}
}

Add absolutePanel.add( new LoginScreen() );

Replace extends VLayout to Composite

This should basically fix your problem. This is what I'm using in my code so I can easily add and remove classes from the Panel without having to keep all classes in one code.

Please don't mix GWT and SmartGWT components. What error are you receiving from your example code?
