Hi every body
I have a Problem with swimlane layout. I’m trying to get a layout with three Columns and one Row that has the size off 100%. That I wound to split up my nodes between these three Columns. But when I create the lanes it creates me something between the Colum Header and the first row => looks like empty space => please see attached file swimlane.png.
And when I use a FlowLayout to Arrange the Items. My Diagram looks like on the swimlane.png
What I’m doing wrong? Is there any Body how can send me an example for this?
I'm running on Version 5.3.2.23276
My Code for the Flow Layout
[size=9]FlowLayout fl = new FlowLayout();
fl.LayoutRules.PreferredRules = PreferredRules.ConnectorRules;
fl.LayoutRules.ConnectorRules.UpOriented = new string[] { "NN" };
fl.LaneType = LaneType.LaneGrid;
fl.LayoutRules.NodeRules.GroupStartNodes = new string[] { "Start" };
fl.AutoRoute = true;
fl.HorizontalGroupOffset = 8;
fl.VerticalGroupOffset = 2;
fl.NodeDistance = 5;
fl.LevelOffset = 5;
fl.ChangeLaneDimensions = true;
fl.LayoutRules.NodeRules.MainConnectorOrientation = SimpleOrientation.LeftToRight;
fl.Arrange(diagramView1.Diagram);[/size]
Best regards

Hi Stoyan
thank you for the replay. But I'm always using the HookHeader and SwimlaneLayoutTraits.Lane.
Here is the complete Code I’m running maybe there is something else wrong.
Best regards Michael

tc.setupStartSize();
diagram1.Nodes.Add(node);
tc.OpenCloseChange += new EventHandler(RouteAllLinks);
tc.LocationChanged += new EventHandler(RouteAllLinks);
return node;
}

Where can I find this SwimlaneLayout (Namespace, DLL)???
I have a reference to all Mindfusion DLLs but there is now SwimlaneLayout. Or is this a Problem from the Version 5.3.2.23276?
Where can I find an Example for this?
Best regards
Michael

ok then I first have to bye an update to the newes Version
thx for the Help

Could you attach the saved diagram as xml file and post your layout code? I can't see this happening with the default layout settings and only layout.Orientation set to Vertical.

This seems to happen because of HookHeaders, now the headers overlap the upper part of the grid because of Y scroll offset. It should look ok if you disable HookHeaders. Also try setting diagram1.LaneGrid.ColumnHeadersHeights = new float[] { 8 } to remove the space between headers and grid.

I hope that helps,
Stoyan

Hi,

Your diagram.Bounds starts from 13 and the header is hidden above the top boundary if you disable HookHeaders. Set Bounds to a rectangle with origin at 0,0 and the header will be visible. If the diagram starts from 0, the header will be visible with HookHeaders too and will not overlap the nodes when at top scroll position.

Alternatively you can make the layout class move the whole grid down the diagram by setting its Margin:

diagram.LaneGrid.ColumnHeadersHeights = new float[] { 8 };
SwimlaneLayout l = new SwimlaneLayout();
l.Orientation = MindFusion.Diagramming.Layout.Orientation.Vertical;
l.Margins = new SizeF(
  diagram.LaneGrid.GetRowHeaderBounds().Width + diagram.Bounds.X,
  diagram.LaneGrid.GetColumnHeaderBounds().Height + diagram.Bounds.Y);
l.Arrange(diagram); 

That too should make the headers visible and not overlapping nodes when HookHeaders is disabled or if it's enabled and the diagram is not scrolled.

I hope that helps,
Stoyan
