public interface WLoadingIndicator
The loading indicator displays a message while a response from the server is pending.
By providing a custom implementation of this interface, you may use a custom
loading indicator using
WApplication#setLoadingIndicator(),instead of the default implementation (
You should reimplement this method to return a widget that will be shown to indicate that a response is pending. The widget should be positioned using CSS.
The widget will be shown and hidden using
WWidget#hide(). If you want to
customize this behaviour, you should reimplement the
WWidget#setHidden() method. Note that show() and hide() are stateless
slots, and thus you need to make sure that your implementation comforms
server-side implementation will only be called during stateless slot
Note: The widget will not be added to the
void setMessage(java.lang.CharSequence text)
If the indicator is capable of displaying a text message, then you should reimplement this method to allow this message to be modified.
