Hi,
I am new using gwt and i am using it with gwtext. I am having problems
submitting a form....Here is my code:
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.http.client.Request;
import com.google.gwt.http.client.RequestBuilder;
import com.google.gwt.http.client.RequestCallback;
import com.google.gwt.http.client.RequestException;
import com.google.gwt.http.client.Response;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.RootPanel;
import com.gwtext.client.core.EventObject;
import com.gwtext.client.widgets.Button;
import com.gwtext.client.widgets.Panel;
import com.gwtext.client.widgets.event.ButtonListenerAdapter;
import com.gwtext.client.widgets.form.FormPanel;
import com.gwtext.client.widgets.form.TextField;
public class Main implements EntryPoint{
public void onModuleLoad() {
final Panel panel = new Panel();
final FormPanel formPanel = new FormPanel();
panel.setBorder(false);
panel.setPaddings(15);
formPanel.setLabelWidth(75);
formPanel.setBorder(false);
final TextField titulop = new
TextField("Titulo de la pantalla", "txtTitulo", 200);
titulop.setAllowBlank(false);
titulop.setLabelStyle("width=230");
formPanel.add(titulop);
final TextField np = new TextField("Número de
páginas", "txtNP", 200);
np.setAllowBlank(false);
np.setLabelStyle("width=230");
np.setRegex("^\\d*$");
formPanel.add(np);
final Button save = new Button("Save", new
ButtonListenerAdapter()
{
public void onClick(Button button, EventObject e)
{
//formPanel.getForm().submit("http://localhost/framework/lib/index.php?importar=bantech.clsPantalla.prueba&system=Saseg";,
null, Connection.POST, "Guardando...", false);
//pantalla_detalles();
RequestBuilder.Method method=RequestBuilder.POST;
final String
url1="http://localhost/framework/lib/index.php?importar=bantech.clsPantalla.prueba&system=Saseg";;
RequestBuilder rb=new RequestBuilder(method, url1);
try {
rb.sendRequest(null, new
RequestCallback() {
public void
onResponseReceived(Request request, Response response) {
Window.alert("Respondio "+response.getStatusCode());
if (response.getStatusCode()==200){
//formPanel.getForm().submit();
pantalla_detalles();
}
}
public void onError(Request
arg0, Throwable arg1) {
Window.alert("error");
}
});
}catch (RequestException ex) {
Window.alert("ERROR"+ex);
}
}
private void pantalla_detalles() {
Panel pd = new Panel();
pd.setBorder(false);
pd.setPaddings(15);
FormPanel formDetalles = new FormPanel();
formDetalles.setFrame(true);
formDetalles.setTitle("Detalles de la pantalla");
formDetalles.setWidth(600);
formDetalles.setLabelWidth(75);
formDetalles.setUrl("../procesardatapantalla.php?proce=guardar_pantalla");
TextField pg = new TextField("Página","txtpagina",230);
formDetalles.add(pg);
pd.add(formDetalles);
RootPanel.get().add(pd);
}
});
formPanel.addButton(save);
panel.add(formPanel);
RootPanel.get().add(panel);
}
}
The answer of the server it's in JSON format. If i use a
formPanel.getForm().submit("http://localhost/framework/lib/index.php?importar=bantech.clsPantalla.prueba&system=Saseg";,
null, Connection.POST, "Guardando...", false); instead of using
RequestBuilder the submit is perform but i need to have the answer of
the server and i read that using RequestBuilder is the only way.
Thanks in advance
