  - setAllExpanded
```
void setAllExpanded(boolean newAllExpanded)
```
    Sets whether all tree nodes are expanded. This method delegates to the root node TreeNodeModel.setAllExpanded(boolean).
    
    Parameters:
    
    newAllExpanded - true if all the nodes should be expanded, or false if they should be collapsed.
