Re: Help: How to refresh Button Text?

Why you add again the button in refreshStopList()?

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

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);

 }
