What's New in this Release

The list below describes recent changes and additions to JsDiagram:

New in version 4.4.4

New mouse events

• nodePointed event has been replaced by a set of more specific events: nodePointerEnter and nodePointerLeave are raised when the mouse pointer respectively enters or leaves the boundaries of a node. nodeHovered fires if the pointer rests over a node for hoverDelay milliseconds.
• linkPointed event has been replaced by a set of more specific events: linkPointerEnter and linkPointerLeave are raised when the mouse pointer respectively enters or leaves the boundaries of a link. linkHovered fires if the pointer rests over a link for hoverDelay milliseconds.

Miscellaneous

• Enable the autoDeleteChildren property to automatically delete child nodes when a container is deleted.
• Fix for custom Shape definitions not setting the id property.
• Fix for selected property setter of DiagramItem not immediately reflecting assigned value due to async calls.

API changes

• linkPointed and nodePointed events replaced by linkHovered and nodeHovered.

New in version 4.4.3

• Due to problems with some script loaders, the library no longer registers web components automatically. Call the WebComponents.register method to explicitly register component classes.
• Set cornerRadius to change the size of corners when node's shape is set to a rounded rectangle.
• Set the autoDeleteLinks property to false to prevent deleting links along with a node they connect, and disconnect the links instead.
• Fixed a bug where child nodes keep reference to their deleted container.

New in version 4.4.2

TableNode improvements

• getRow and getColumn methods now return strongly-typed TableRow and TableColumn objects.
• The anchorPattern property of TableRow and rowAnchorPattern property of TableNode let you specify the points where links connect to table rows.
• cellTextColor property lets you set default color of cell texts, without changing caption color.

TabbedDiagramView improvements

• Enable allowRenamePages to let users edit the title of DiagramPage by clicking the active tab.
• The control raises pageAdding event when users click the plus icon to let you validate the operation, and pageAdded once the page is added.
• The control raises pageRemoving event when users close a tab to let you validate the operation, and pageRemoved once the page is removed.
• Fix for scroll range not updating when changing tabs.

Miscellaneous

• Disable allowUnanchoredLinks to prevent users from drawing links to nodes without designated anchor points.
• Set inplaceEditAcceptOnEnter and inplaceEditCancelOnEsc properties to specify whether edit operations end when user presses respectively Enter and Esc keys.
• The showAnchors property can be set to Selected | Auto combination.
• Set horizontalDropAlignment and verticalDropAlignment properties to specify how nodes are positioned relatively to the drop point after drag operations from NodeListView.
• Set dragIndicatorOpacity property to specify the opacity of drag indicator displayed during drag-and-drop operations.

New in version 4.4.1

• Angular bindings updated to Angular version 16.
• Custom-draw anchor points by setting MarkStyle.Custom and handling drawAnchorPoint event.
• SinglePointerController can now be inherited from TypeScript.
• Fix for allowUnconnectedLinks not working when allowSelfLoops is disabled.
• Set validityChecks to false to add items faster.
• Fix for ControlNodes drawing on top of DiagramView's scrollbars.
• Fixed XML serialization of unconnected links.
• Fixed exception when moving multiple selection in TabbedDiagramView.
• Fixed NodeListView exception for nodes with rotation handle.
• Blazor bindings moved to MindFusion.Diagramming.JavaScript nuget package.

New in version 4.4

Web components

The library registers each control class as a web component. You can use the following tags to create corresponding components:

• <mindfusion-diagramview> creates a DiagramView instance.
• <mindfusion-ruler> creates a Ruler instance.
• <mindfusion-zoomcontrol> creates a ZoomControl instance.
• <mindfusion-overview> creates an Overview instance.
• <mindfusion-nodelistview> creates a NodeListView instance.

When instantiated as a web component, each control class creates required HTML elements as internal shadow DOM. You can get the JavaScript object corresponding to a web component by calling controls' find method with id argument.

HTML

<mindfusion-diagramview
    id="diagramView"
    style="position: absolute; left: 0px; top: 0px; right: 0px; bottom: 0px; overflow: auto;">
</mindfusion-diagramview>

JavaScript

var diagramView = DiagramView.find("diagramView");
var diagram = diagramView.diagram;

Animations

The library now includes several standard animation classes and methods.

The animate method of DiagramItem can run following animations:

• FillColorAnimation animates the fill color of nodes or link arrowheads.
• StrokeColorAnimation animates the color of node borders or link segments.
• OpacityAnimation animates items' opacity for fade-in and fade-out effects.

Following animations can be applied to DiagramNodes:

• BounceAnimation animates vertical position of nodes.
• ShakeAnimation animates horizontal position of nodes.
• PulseAnimation animates node's local scale factor.
• PathAnimation moves nodes along specified path.

The animate method of DiagramView can run following animations:

• ScrollAnimation animates the scroll position of a view.
• ZoomAnimation animates the zoom factor of a view.

DiagramLink improvements

• Set the intermediateShape property to display arrowheads at the middle of each link segment. This could help users follow longer link paths. Intermediate arrowheads can be customized further by setting intermediateBrush and intermediateShapeSize.
• Set the allowSplitLinks property of Diagram to let users insert new link segments by dragging any point of a selected link's segment. In this mode users can also merge link segments by making them close to collinear, or by moving adjustment handles close to each other, as set via mergeThreshold.
