You need to provide a different factory for each line type.

Does all line must created with ConnectionCreationToolEntry?

the factory that i must providered means SimpleFactory?
____________________________________________________________ _________________
ConnectionCreationToolEntry conn = new ConnectionCreationToolEntry(
LogicMessages.LogicPlugin_Tool_CreationTool_TopoLine_Label, LogicMessages.LogicPlugin_Tool_CreationTool_TopoLine_Descrip tion,
new SimpleFactory(TopoLine.class),
ImageDescriptor.createFromFile(TopoLine.class,"icons/topoline16.gif "),
ImageDescriptor.createFromFile(TopoLine.class, "icons/topoline24.gif"));

entries.add(conn);

logic's connection entry is:

tool = new ConnectionCreationToolEntry(
LogicMessages.LogicPlugin_Tool_ConnectionCreationTool_Connec tionCreationTool_Label,
LogicMessages.LogicPlugin_Tool_ConnectionCreationTool_Connec tionCreationTool_Description,null,
ImageDescriptor.createFromFile(ODF.class,"icons/connection16.gif "),
ImageDescriptor.createFromFile(ODF.class, "icons/connection24.gif"));

entries.add(tool);

Does logic's connection's model should be Wire? but it seems that the
upper code not relate a model with a connection entry.because fatory is
null.

if i create my line ,Does i must create a editpart like LogicEditPart? or
in

public ConnectionAnchor getSourceConnectionAnchor(ConnectionEditPart
connEditPart){
Wire wire = (Wire) connEditPart.getModel();
return getNodeFigure().getConnectionAnchor(wire.getSourceTerminal() );
}

change code to

public ConnectionAnchor getSourceConnectionAnchor(ConnectionEditPart
connEditPart){
if (connEditPart instanceof Wire ){
Wire wire = (Wire) connEditPart.getModel();
return getNodeFigure().getConnectionAnchor(wire.getSourceTerminal() );
}else if (connEditPart instanceof MyLine ){
MyLine myLine= (MyLine) connEditPart.getModel();
return getNodeFigure().getConnectionAnchor(myLine.getSourceTerminal ());
}
}
