Method Detail

loadChildren

public void loadChildren()

Loads this branch info's children. The children list is initialized to null and loaded lazily to allow the skin to only create NodeInfo objects for the nodes that it actually needs in order to paint. Thus, it is the responsibility of the skin to check if children is null and call loadChildren() if necessary.

isExpanded

public boolean isExpanded()

setExpanded

public void setExpanded(boolean expanded)
