从Java中的另一个文本字段传递文本字段值

Question

I have two textfields using gwt and I would like to pass the text that I have in my first textfield in to my second textfield

name = txtName.getText();
TextField txtName = new TextField();
txtName.setAllowBlank(false);
txtName.setEmptyText("c.gornez");
vlc.add(new FieldLabel(txtName, "Name"), new VerticalLayoutData(1, -1, new Margins(10)));
name = txtName.getText();

TextField txtMailbox = new TextField();
txtMailbox.setAllowBlank(false);
txtMailbox.setEmptyText("c.gornez");
vlc.add(new FieldLabel(txtMailbox, "Mailbox"), new VerticalLayoutData(1, -1, new Margins(10)));
mailbox = txtMailbox.getText();

Answer 1

这应该工作

txtMailbox.setText(txtName.getText())

Answer 2

If you want change txtMailBox after each change of txtName value, you should add a value change handler to txtName (see code below).

txtName.addValueChangeHandler ( new ValueChangeHandler<String>() {
  @Override
  public void onValueChange(ValueChangeEvent<String> event) {
    final String name = event.getValue()
    txtMailBox.setText(name);
  }

});
