Ok, in war/MyProject.html, I have:
<body>
<div id="loading">
<div id="waitingForLoading"></div>
<BR/>
<img src="../images/loading.gif" />
</div>
...
</body>
in MyProject.java
public class OfflineMatching implements EntryPoint {
@Override
public void onModuleLoad() {
// this code works fine
if(DOM.getElementById("loading")!=null){
DOM.getElementById("loading").removeFromParent();
}
Button myButton=new Button("Enter Main Page");
RootPanel.get().add(myButton);
myButton.addClickHandler(new ClickHandler(){
@Override
public void onClick(ClickEvent event) {
// this code does not work
if(DOM.getElementById("loading")==null){
DOM.appendChild(RootPanel.getBodyElement(),
DOM.createElement("loading"));
}
}
});
}
}
So, did i do anything wrong? Why this code does not work?
// this code does not work
if(DOM.getElementById("loading")==null){
DOM.appendChild(RootPanel.getBodyElement(),
DOM.createElement("loading"));
}
