What's New in this Release

The list below describes recent changes and additions to MindFusion.Diagramming for .NET MAUI:

New in version 1.2

Spatial index

Set the EnableSpatialIndex property of Diagram to create an index of item positions for faster hit-testing and viewport clipping queries. This should greatly improve user interaction and rendering speed for diagrams containing tens of thousands or more items.

C#

// create 20000 links + nodes in total
for (int i = 0; i < 10000; i++)
{
    var node = diagram.Factory.CreateShapeNode(x, y, size, size);
    node.Text = i.ToString();
    if (x > diagram.Bounds.Left)
    {
        diagram.Factory.CreateDiagramLink(
            diagram.Nodes[i - 1], diagram.Nodes[i]);
    }

    x += dist;
    if (x >= diagram.Bounds.Right)
    {
        x = diagram.Bounds.Left;
        y += dist;
    }
}

diagram.EnableSpatialIndex = true;

Miscellaneous

• DividerPen property added to ContainerNode, TableNode and TreeViewNode classes. It lets you customize the appearance of the divider line drawn between a node's caption bar and content area.
• The ShowScrollbars property lets you hide diagram view's scrollbars.
• Fix for Diagram property setter not repainting the view.
