Hello Robert,
I am certainly having trouble explaining this one.
I am using the Eclipse IDE with the Google AppEngine Plugin.
When I create a New Web Application Project an AppEngine Application
is generated.
This includes one HTML page some Java code that implements the RPC
services and a couple of XML files that establish the Servelet Mapping
and Entry point for the Application.
I think that I have some (not great) idea of what all of this is
doing.
In the onModuleLoad of the EntryPoint for the generated Application a
Submit button is added to the only HTML page,
A ClickHandler with a ClickEvent is added to ‘listen’ for the user to
Click on the Submit button.
The sendButtonContainer is defined in the one and only HTML file.
This is in the onModuleLoad on the EntryPoint class.
final Button sendButton = new Button("Send");
RootPanel.get("sendButtonContainer").add(sendButton);
class MyHandler implements ClickHandler, KeyUpHandler
{
public void onClick(ClickEvent event)
{
sendNameToServer();
}
public void onKeyUp(KeyUpEvent event)
{
if (event.getNativeKeyCode() == KeyCodes.KEY_ENTER)
{
sendNameToServer();
}
}
}
My Launch button (the equivalent of the Submit button) is not on the
first and only page of the Application.
I just can’t seem to grasp the concept of how to ‘listen’ for my
Launch button on the HTML page that it is defined in.
Thanks,
Raney
