我正在开发一个需要表单的应用程序，但我不知道如何制作它。我正在寻找有用的信息（手册、书籍等），但找不到任何有用的信息。我想制作一个表格，当用户点击按钮时，我想收集表格中的信息。
我正在使用 GWT 和 UiBinder 进行开发。
InterfazUsuario.ui.xml：
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
>
<g:DockLayoutPanel unit='EM'>
<g:center>
<g:FormPanel ui:field="form" action="/InterfazUsuario">
<g:HTMLPanel height="427px">
<g:Label text="Idioma:" width="49px"/>
<g:ListBox visibleItemCount="1" name="lbIdioma" width="118px" ui:field="rellenarIdioma"/>
<g:Label text="Tipo de Recurso:" width="100px"/>
<g:ListBox ui:field="rellenarTipoRecurso" name="lbTipoRecurso" visibleItemCount="1" width="118px"/>
<g:Label text="Motor de Búsqueda:" width="125px"/>
<g:ListBox name="lbMotorBusqueda" visibleItemCount="1" width="118px"/>
<g:Label text="Consulta:" width="125px"/>
<g:TextBox visibleLength="50" name="txtConsulta"/>
<g:Label text="Número de Recurso:" width="125px"/>
<g:ListBox name="lbNumRecurso" visibleItemCount="1" width="118px"/>
<g:Label text="Matriz:" width="125px"/>
<g:ListBox name="lbMatriz" visibleItemCount="1" width="118px"/>
<g:Label text="Fila:" width="125px"/>
<g:ListBox name="lbFila" visibleItemCount="1" width="118px"/>
<g:Label text="Columna:" width="125px"/>
<g:ListBox name="lbColumna" visibleItemCount="1" width="118px"/>
<g:Button width="142px" text="Aceptar" ui:field="btnAceptar"/>
</g:HTMLPanel>
</g:FormPanel>
</g:center>
</g:DockLayoutPanel>

public InterfazUsuario(List<String> idiomas, List<String> tipoRecurso){
System.out.println("Entra en el constructor");
// sets listBox
initWidget(binder.createAndBindUi(this));
for (Iterator iter = idiomas.iterator(); iter.hasNext();) {
System.out.println("Entra en el primer for");
String name = (String) iter.next();
rellenarIdioma.addItem(name);
}
System.out.println(rellenarIdioma.getItemText(1));
for(Iterator iter = tipoRecurso.iterator(); iter.hasNext();){
String tipoRec = (String) iter.next();
rellenarTipoRecurso.addItem(tipoRec);
}
System.out.println("vamos a salir del constructor");
// Add an event handler to the form.
form.addSubmitHandler(new FormPanel.SubmitHandler() {
public void onSubmit(SubmitEvent event) {
Window.alert("The text box must not be empty");
}
});
form.setAction("/InterfazUsuario");
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
form.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() {
@Override
public void onSubmitComplete(SubmitCompleteEvent event)
{Window.alert(event.getResults());
}
});
System.out.println("despues de llamar al handler");
System.out.println(form.getMethod());
}
@UiHandler("btnAceptar")
public void onClick(ClickEvent event) {
form.submit();
}
public InterfazUsuario(){
}
谢谢。
