    Table Port Distribution Modes
    In This Topic
     Overview

    Table shapes as all other shapes use ports to connect to other shapes, but because table shapes are more complex and can hold more data than a simple shape the question about the proper port distribution arises. In order to cover all scenarios, Nevron Diagram provides you 3 ways of table shape port distribution:

    • ShapeBased - treats the table shape as a rectangle and adds a port to each side
    • GridBased - treats the table shape as a set of row and columns and adds a port at the beginning and the end of each row and column
    • CellBased - treats the table shape as a set of table cells and adds a port to the outer sides of each cell

    The following picture illustrates the effect of the different port distribution modes:

     Code Example

    The above diagram can be created using the following code fragments:

    Port Distribution Modes Example
    Copy Code 
    private NTableShape CreateTableShape(TablePortDistributionMode portDistributionMode)
{
      NTableShape tableShape = new NTableShape(400, 400, 100, 100);
      tableShape.PortDistributionMode = portDistributionMode;
      tableShape.CellPadding = new Nevron.Diagram.NMargins(10);
      tableShape.InitTable(3, 3);
      tableShape.BeginUpdate();
      for (int i = 0, rowCount = tableShape.RowCount; i < rowCount; i++)
      {
            for (int j = 0, columnCount = tableShape.ColumnCount; j < columnCount; j++)
            {
                  tableShape[j, i].Text = String.Format("Cell {0}", i * columnCount + j + 1);
            }
      }
      tableShape[0, 1].ColumnSpan = 2;
      tableShape[0, 1].RowSpan = 2;
      tableShape.EndUpdate();
      return tableShape;
}

private void InitDocument(NDrawingDocument document)
{
      Array modes = Enum.GetValues(typeof(TablePortDistributionMode));
      for (int i = 0; i < modes.Length; i++)
      {
            TablePortDistributionMode mode = (TablePortDistributionMode)modes.GetValue(i);
            NTableShape tableShape = CreateTableShape(mode);
            document.ActiveLayer.AddChild(tableShape);
            document.ActiveLayer.AddChild(new NTextShape(mode.ToString() + " port distribution", 0, 0, 100, 30));
      }
      NTableLayout tableLayout = new NTableLayout();
      tableLayout.Direction = LayoutDirection.LeftToRight;
      tableLayout.ConstrainMode = CellConstrainMode.Ordinal;
      tableLayout.MaxOrdinal = 2;
      tableLayout.HorizontalSpacing = 30;
      tableLayout.VerticalSpacing = 30;
      NNodeList shapes = document.ActiveLayer.Children(NFilters.Shape2D);
      tableLayout.Layout(shapes, new NDrawingLayoutContext(document));
      document.SizeToContent();
