*
|
|
* ViewHolder is used to connect a single View to a Gui instance. This is useful in smaller applications
|
|
* with a simple user interface. If advanced view switching capabilites are required, consider using ViewDispatcher instead.
|
|
*
|
|
* @warning Views added to a ViewHolder MUST NOT be in a ViewStack at the same time.
