1.5.0

Added

• The ability to have ports on groups.
• EXPERIMENTAL/INCOMPLETE Nested groups. Since GroupModel now inherits NodeModel, it became possible to have nested groups, but there are still problems with the order of links between groups.
• A Class parameter to GroupContainer.

Changed

• Only rerender groups when necessary.
• Receiving the same size from ResizeObserver doesn't trigger a rerender anymore.
• Avoid rerendering ports twice to update positions.
• Avoid rerendering ports when their parent node is moving.
• Padding is now handled in GroupModel instead of GroupContainer (UI). This is because the padding is necessary to have accurate size/position in the group model directly.

Fixed

• Use @key when rendering the list of groups. Not using it caused big/weird render times.
• Groups not showing in Navigator/Overview.

1.4.2

Added

• Locked nodes now have a locked class and their cursor is changed to pointer.

1.4.1

Added

• EnableVirtualization option: whether to only render visible nodes or not.
• RegisterModelComponent overload that takes Types as input for dynamic registrations.

1.4.0

Added

• Two zoom related options, Minimum and Maximum, to clamp the zoom value.

Changed

• [BREAKING] Grouped zoom related options into DiagramZoomOptions, available unnder Options.Zoom.
  • The option AllowZooming was renamed to Enabled.
  • The option InverseZoom was renamed to Inverse.

Fixed

• The diagram canvas' container wasn't updated when the user scrolls (#51).

1.3.0

Added

• Abstract MovableModel, which inherits from SelectableModel and represents models that can be move with the mouse (e.g. nodes and groups).
• Groups widget customization using RegisterModelComponent.
• SizeChanged event on NodeModel.

Changed

• SelectableModel is now abstract.
• Groups:
  • Renamed model Group to GroupModel.
  • Rendered as a single entity (HTML div) with padding.
  • Movable and Selectable.
  • Selecting a node inside a group doesn't select the others anymore.
• [BREAKING] Renamed DiagramManager.ChangePan to UpdatePan.
• [BREAKING] Renamed DiagramManager.ChangeZoom to SetZoom.

Fixed

• ZoomToFit wasn't unhiding hidden nodes.

1.2.0

Added

• DefaultLinkModel in DiagramLinkOptions (@joezearing).
• Ability to change source/target ports of a link (SetSourcePort and SetTargetPort).
  The methods also trigger the new events SourcePortChanged and TargetPortChanged.

Changed

• Curved link paths now take into account the ports alignements and a margin (@joezearing).
• The AddLink<T>(T link, PortModel source, PortModel? target = null) overload in DiagramManager is now public.
  This is useful when developers want to create the link instance themselves, DiagramMananger will setup ports and trigger appropriate events.

Fixed

• GetMiddleTargetX and GetMiddleTargetY using SourcePort instead of TargetPort (@joezearing).

1.1.3

Fixed

• Diagram Container not ready when ports/nodes need it.

1.1.2

Added

• Drag & Drop demo.
• Helper method DiagramManager.GetRelativePoint.

Fixed

• Diagram container resizes don't update the offsets/position (top/left).
• Container changes don't trigger node visibility checks.
• Ports aren't refreshed when nodes are resized.

1.1.0

Added

• Track mouseup events on nodes @joriskalz.
• Zooming in/out will now trigger the nodes visibility check.
• AllowZooming and AllowPanning options.
• DefaultColor and DefaultSelectedColor link options.
• Custom ports/links demos/documentation.
• Options documentation.

Changed

• Group link related options into DiagramLinkOptions, available in DiagramOptions.Links.
• All link related calculations (e.g. MiddleSourceX) are now extension methods available in LinkModelExtensions.

Removed

• LinkWidget's behind file is not needed anymore.
