Method Details

getWidget

public WWidget getWidget()

Returns the widget that visually represents the indicator.

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.show() and WWidget.hide(). If you want to customize this behaviour, you should reimplement the WWidget#setHidden() method. Note that WWidget.show() and WWidget.hide() are stateless slots, and thus you need to make sure that your implementation comforms to that contract, so that it may be optimized to JavaScript (the server-side implementation will only be called during stateless slot prelearning).

Note: The widget will not be added to the WApplication.getRoot() container.

Specified by:

getWidget in interface WLoadingIndicator

setMessage

public void setMessage(java.lang.CharSequence text)

Description copied from interface: WLoadingIndicator

Sets the message that you want to be displayed.

If the indicator is capable of displaying a text message, then you should reimplement this method to allow this message to be modified.

setMessage in interface WLoadingIndicator
