Hi.

Maybe Im blind or I tried to search wrong keywords, but i cant find something about this issue.

I have diagram with many links various LinkStyle. Im using 11 types of layouting so user can choose one:

  Private MoGridLayout As GridLayout = New GridLayout
    Private MoLayeredLayout As LayeredLayout = New LayeredLayout
    Private MoSpringLayout As SpringLayout = New SpringLayout
    Private MoTreeLayout As TreeLayout = New TreeLayout
    Private MoAnnealLayout As AnnealLayout = New AnnealLayout
    Private MoOrthogonalLayout As OrthogonalLayout = New OrthogonalLayout
    Private MoCircularLayout As CircularLayout = New CircularLayout
    Private MoOrthogonalRouter As OrthogonalRouter = New OrthogonalRouter
    Private MoFlowLayout As FlowLayout = New FlowLayout
    Private MoFlowChartLayout As FlowchartLayout = New FlowchartLayout
    Private MoTopologicalLayout As TopologicalLayout = New TopologicalLayout


How to layout my diagram but to preserve original LinkStyle of all links? Is it possible?

Thx.

Thx Stoyo.

I also set some properties of all links. Is it ok? Another settings are needed? My class is like this:

Imports MindFusion.Diagramming.Layout

Public Class ClsDiagramLayout
    'represents class for diagram layouting with various types of layouts

#Region "Attributes"
#Region "Private attributes"
    'all layout engines
    Private MoGridLayout As GridLayout = New GridLayout
    Private MoLayeredLayout As LayeredLayout = New LayeredLayout
    Private MoSpringLayout As SpringLayout = New SpringLayout
    Private MoTreeLayout As TreeLayout = New TreeLayout
    Private MoAnnealLayout As AnnealLayout = New AnnealLayout
    Private MoOrthogonalLayout As OrthogonalLayout = New OrthogonalLayout
    Private MoCircularLayout As CircularLayout = New CircularLayout
    Private MoOrthogonalRouter As OrthogonalRouter = New OrthogonalRouter
    Private MoFlowLayout As FlowLayout = New FlowLayout
    Private MoFlowChartLayout As FlowchartLayout = New FlowchartLayout
    Private MoTopologicalLayout As TopologicalLayout = New TopologicalLayout

    Private MoAllLayoutEngines As List(Of Layout) = New List(Of Layout)()
#End Region
#End Region
#Region "Events"
    Public Event MMAfterArranged(ByVal TypeOfLayout As GeTypeOfLayout) 'event is raised after arranging a diagram
#End Region
#Region "Constructors"
    Public Sub New()

  'for identifying desired engine in list is used enum GeTypeOfLayout

  MoAllLayoutEngines.Add(MoGridLayout)

  MoAllLayoutEngines.Add(MoLayeredLayout)

  MoAllLayoutEngines.Add(MoSpringLayout)

  MoAllLayoutEngines.Add(MoTreeLayout)

  MoAllLayoutEngines.Add(MoAnnealLayout)

  MoAllLayoutEngines.Add(MoOrthogonalLayout)

  MoAllLayoutEngines.Add(MoCircularLayout)

  MoAllLayoutEngines.Add(MoOrthogonalRouter)

  MoAllLayoutEngines.Add(MoFlowLayout)

  MoAllLayoutEngines.Add(MoFlowChartLayout)

  MoAllLayoutEngines.Add(MoTopologicalLayout)
    End Sub
#End Region
#Region "Subs"
    'arranges given diagram with desired layout engine
    Public Sub Arrange(ByVal IoDiagram As MindFusion.Diagramming.Diagram, ByVal IeTypeOfLayout As GeTypeOfLayout)

  Try


'for identifying desired engine in list is used enum GeTypeOfLayout


Dim LoLayout As Layout = MoAllLayoutEngines(IeTypeOfLayout)


'preserving original links tyles of all links



'backuping original link styles of all links


Dim LoOriginalLinkStyles As Dictionary(Of ClsMMLinkNode, MindFusion.Diagramming.LinkStyle) = New Dictionary(Of ClsMMLinkNode, MindFusion.Diagramming.LinkStyle)


For Each LoLinkNode As ClsMMLinkNode In IoDiagram.Links


    LoOriginalLinkStyles.Add(LoLinkNode, LoLinkNode.Style)


Next


LoLayout.Arrange(IoDiagram)


'restoring original link styles of all links


For Each LoLinkNode As ClsMMLinkNode In IoDiagram.Links


    LoLinkNode.Style = LoOriginalLinkStyles(LoLinkNode)


    LoLinkNode.SnapToNodeBorder = True


    LoLinkNode.AutoRoute = True


    LoLinkNode.AllowMoveStart = True


    LoLinkNode.AllowMoveEnd = True


    LoLinkNode.Dynamic = True


Next



'rerouting all links


IoDiagram.RouteAllLinks()



RaiseEvent MMAfterArranged(IeTypeOfLayout)

  Catch ex As Exception


LogEventFromException(ex, , , )

  End Try
    End Sub

#End Region

End Class

 

Another question - error: after 2-3 times I use OrthogonalRouter layout (not in a row - also combined with another types), theres an error:



Error comes from  LoLayout.Arrange(IoDiagram).

Any ideas?

Thx.

Hi.

I sent it to u.

Another problem which u could examine is:

After selecting a node, it jumps couple of pixels away and immediately get back to its original position. Theres no events NodeModifying or NodeModified so its just "graphic" problem.

I have my own WinForms.Behaviors.BehaviorBase class assigned into diagram:

Me.fcDiagramView.CustomBehavior = New ClsCustomBehavior(Me.fcDiagramView)

Any ideas?


Thx.
