Examples of org.apache.pivot.wtk.Component

org.apache.pivot.wtk.Component
Top level abstract base class for all components. In MVC terminology, a component represents the "controller". It has no inherent visual representation and acts as an intermediary between the component's data (the "model") and the skin, an implementation of {@link Skin} which serves asthe "view".

    ComponentMouseWheelListener, ComponentKeyListener {

            String tooltipText = component.getTooltipText();


            // The tooltip text may have been cleared while the timeout was
            // outstanding; if so, don't display the tooltip
            if (tooltipText != null) {
                final Tooltip tooltip = new Tooltip(tooltipText);


                Point location = component.getDisplay().getMouseLocation();
