I've seen in the Diagram Designer application a Connector Shapes group in Library Browser but i cant find a Connector Factory. How did you added those connectors to library browser?

Hi Marius,
The connectors library group is generated for a library document on which the InitWithConnectors method has been called. The connectors are not available by a factory on purpose - all other factories are generally creating 2D shapes, which makes it possible to assign a default size to the shapes. Connectors are different - driven only by their end points. There is nothing special about the InitWithConnectors method - following is its current code:
public virtual void InitWithConnectors(NMeasurementUnit measurementUnit, NSizeF connectorSize)
{
if (connectorSize.Width == 0 || connectorSize.Height == 0)
throw new ArgumentException("##Connectors size width and height must not be 0", "connectors");
BeginInit();
RemoveAllChildren();
NRectangleF bounds = new NRectangleF(0, 0, connectorSize.Width, connectorSize.Height);
NPointF[] corners = bounds.Vertices;
// add line connector
NLineShape lineConnector = new NLineShape(corners[0], corners[2]);
lineConnector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(lineConnector, measurementUnit, "Line Connector", ""));
// add bezier connector
NBezierCurveShape bezierConnector = new NBezierCurveShape(corners[0], corners[1], corners[3], corners[2]);
bezierConnector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(bezierConnector, measurementUnit, "Bezier Connector", ""));
// add HV first horizontal
NStep2Connector step2Connector = new NStep2Connector(corners[0], corners[2], false);
step2Connector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(step2Connector, measurementUnit, "Side to top/bottom", ""));
// add HV first vertical
step2Connector = new NStep2Connector(corners[0], corners[2], true);
step2Connector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(step2Connector, measurementUnit, "Top/bottom to side", ""));
// add Side to Side connector
NStep3Connector step3Connector = new NStep3Connector(corners[0], corners[2], false, 50, 0, true);
step3Connector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(step3Connector, measurementUnit, "Side to side", ""));
// add Top to Bottom connector
step3Connector = new NStep3Connector(corners[0], corners[2], true, 50, 0, true);
step3Connector.StyleSheetName = NDR.NameConnectorsStyleSheet;
AddChild(new NMaster(step3Connector, measurementUnit, "Top to bottom", ""));
// add arrow connectors
foreach (ArrowType arrowType in Enum.GetValues(typeof(ArrowType)))
{
NArrowShape arrowShape = new NArrowShape();
arrowShape.StyleSheetName = NDR.NameConnectorsStyleSheet;
(arrowShape.Primitive as NArrowPath).DefineModel(arrowType, corners[0], corners[2]);
string name = NSystem.InsertSpacesBeforeUppers(arrowType.ToString());
AddChild(new NMaster(arrowShape, measurementUnit, name, ""));
}
// add routable connectors
foreach (RoutableConnectorType routableConnectorType in Enum.GetValues(typeof(RoutableConnectorType)))
{
NRoutableConnector routableConnector = null;
switch (routableConnectorType)
{
case RoutableConnectorType.DynamicHV:
routableConnector = new NRoutableConnector(new NPointF[3] { corners[0], corners[3], corners[2] });
break;
case RoutableConnectorType.DynamicPolyline:
routableConnector = new NRoutableConnector(RoutableConnectorType.DynamicPolyline, new NPointF[2] { corners[0], corners[2] });
break;
case RoutableConnectorType.DynamicCurve:
routableConnector = new NRoutableConnector(RoutableConnectorType.DynamicCurve, new NPointF[2] { corners[0], corners[2] });
break;
}
routableConnector.StyleSheetName = NDR.NameConnectorsStyleSheet;
string name = NSystem.InsertSpacesBeforeUppers(routableConnectorType.ToString());
AddChild(new NMaster(routableConnector, measurementUnit, name, ""));
}
// init document info
Info.Author = "Nevron";
Info.Category = "Connectors";
Info.Company = "Nevron";
Info.Title = "Connector shapes";
EndInit();
IsModified = false;
}
Best regards,
Ivo
