render

protected void render(EnumSet<RenderFlag> flags)

Description copied from class: WWidget

Renders the widget.

This function renders the widget (or an update for the widget), after this has been scheduled using scheduleRender().

The default implementation will render the widget by serializing changes to JavaScript and HTML. You may want to reimplement this widget if you have been postponing some of the layout / rendering implementation until the latest moment possible. In that case you should make sure you call the base implementation however.

Overrides:

render in class WPaintedWidget

paintEvent

protected void paintEvent(WPaintDevice paintDevice)

Description copied from class: WPaintedWidget

Paints the widget.

You should reimplement this method to paint the contents of the widget, using the given paintDevice.

Specified by:
