Assuming you already have a reference to the
VConsoleProperties object, you first need to to get a reference to the display model:
VDisplayModel model =
(VDisplayModel)(properties.getPropertyObject(VConsoleProperties.DISPLAY);
To select specific nodes, where vSelected is a Vector of VScopeNode objects:
model.setSelectedNodes(vSelected);
To select a range of nodes by index:
model.setSelectionInterval(index0, index1);
To select all nodes:
model.selectAll();
To unselect all nodes:
model.clearSelection();
