Method Detail

assignNodeToWidget

void assignNodeToWidget(NODE node,
                        WIDGET widget)

This method assigns the given <NODE> to the given widget.
As a simple example <WIDGET> may be UiWidgetLabel and <NODE> may be String. Then this method would simply do widget.setLabel(node).
ATTENTION:
The UiWidgetRegular may be reused for optimal performance if the <NODE> has changed or been removed. Therefore this method needs to reset and update the entire state of the UiWidgetRegular.

Parameters:

node - is the <NODE> to assign.

widget - is the UiWidgetRegular that is to be assigned. It has initially been created via UiSingleWidgetFactory.create(net.sf.mmm.client.ui.api.UiContext).
