Help: How to refresh Button Text?

Hi All,

I am new to GWT and was trying to create an horizontal panel with 5
Buttons on it. So far, so good.

Point is that when I implemented the method that would define what to
be written in each Button it did not work.

Can anyone helpe me?

Thanks,
Rodrigo

public void onModuleLoad() {

hPanel.setSpacing(10);

// Add some content to the panel
hPanel.add(Stop1Button);
Stop1Button.addStyleName("B1");
hPanel.add(Stop2Button);
Stop2Button.addStyleName("B2");
hPanel.add(Stop3Button);
Stop3Button.addStyleName("B3");
hPanel.add(Stop4Button);
Stop4Button.addStyleName("B2");
hPanel.add(Stop5Button);
Stop5Button.addStyleName("B1");

// Associate the Main panel - hPanel - with the HTML host page.
RootPanel.get("stopList").add(hPanel);

// Setup timer to refresh list periodically.
Timer refreshTimer = new Timer() {
@Override
public void run() {
refreshStopList();
}
};
refreshTimer.scheduleRepeating(REFRESH_INTERVAL);
}

private void refreshStopList() {

// For testing purpose, generate a second screen with different
text then the first one

// hPanel is cleared
hPanel.clear();

// I could do it altogether , but am testing if it is working step
by step
// Text generated in tester is associated with a variable
textButton1 = "Test 1";
// Text received is attributed to a button
Stop1Button.setText(textButton1);

// Button is added to the Screen.
hPanel.add(Stop1Button);

// hPanel is associated with the screen
RootPanel.get("stopList").add(hPanel);

}
