示例1: listenTo
import com.google.gwt.user.client.ui.TextBoxBase; //导入方法依赖的package包/类
public void listenTo(TextBoxBase tb) {
strings.put(tb, tb.getText().trim());
tb.addKeyPressHandler(this);
// Is there another way to capture middle button X11 pastes in browsers
// which do not yet support ONPASTE events (Firefox)?
tb.addMouseUpHandler(this);
// Resetting the "original text" on focus ensures that we are
// up to date with non-user updates of the text (calls to
// setText()...) and also up to date with user changes which
// occurred after enabling "widget".
tb.addFocusHandler(
new FocusHandler() {
@Override
public void onFocus(FocusEvent event) {
strings.put(tb, tb.getText().trim());
}
});
// CTRL-V Pastes in Chrome seem only detectable via BrowserEvents or
// KeyDownEvents, the latter is better.
tb.addKeyDownHandler(this);
