Change port position

Change port position

To change the port position, use the SetLocationRatio method of the IPort object. The port position is set as a double value ratio between 0 and 1.

public void SetLocationRatio(ICommandContext c, ICommandParams p) 
{ 
IDiagram diagram = c.App.Workspace.CurrentEditor as IDiagram; 
if (diagram == null) return; 

//Get the selected node 
var nodes = diagram.GetSelectedShapes().OfType<INode>(); 

//Process each node 
foreach (INode node in nodes) 
{ 
IPortCollection ports = node.Ports; 
int count = 0; 
int max = ports.Count(); 

//Process each port that the node has 
foreach (IPort port in ports) 
{ 
double ratio = (double)count/(double)max; 
port.SetLocationRatio(ratio); 
c.App.Output.WriteLine("sample", $"Port location ratio : {port.LocationRatio}"); 
count++; 
} 
} 
} 

Aligning ports

To align ports, use the RelocatePorts of the INode object. You can specify the side to align with the PortOrientation enumeration. The enumeration values ​​that can be specified are as follows.

Enumeration value	Alignment target
Top	Top side
Left	Left side
Bottom	Bottom side
Right	Right side
All	All four sides

public void RelocatePorts(ICommandContext c, ICommandParams p) 
{ 
IDiagram diagram = c.App.Workspace.CurrentEditor as IDiagram; 
if (diagram == null) return; 

var nodes = diagram.GetSelectedShapes().OfType<INode>(); 

foreach (INode node in nodes) 
{ 
//Align the ports of the node 
node.RelocatePorts(PortOrientation.All); 
} 
}
