GoJS, a JavaScript Library for HTML Diagrams changelog

Changelog History

Page 1

• v2.1.8

  February 05, 2020

  🔄 Changes for 2.1.8

  • ➕ Added the Game of Life cellular automation sample.
  • 🐎 You can improve the performance of an Overview that is observing a large diagram with a visible Diagram.grid by setting Overview.drawsTemporaryLayers to false.
  • 👌 Improved the behavior from 2.1.7 when trying to open text editors in multiple diagrams. A new text editor can be started only if the previous one was able to be accepted. If TextBlock.textValidation or TextEditingTool.textValidation fails, focus remains in that older editor and a new one cannot be started.
  • 🛠 Fixed exception during copy-dragging when some parts are not Part.copyable.

• v2.1.7

  January 29, 2020

  • ➕ Added the Packed Hierarchy sample, which demonstrates a custom PackedLayout for nested circular groups.
  • ➕ Added an optional argument to Diagram.clearSelection, and allowed that method to be overridden.
  • 💻 The TextEditingTool now only allows one active text editor globally, instead of one per Diagram. This avoids some focus problems in various browsers.

• v2.1.6

  January 15, 2020

  🔄 Changes for 2.1.6

  • 🚀 The release/go-module.js file now exports every class, so that you can import only specific classes, instead of go . For example: import { Diagram, Node, Link, Point, Shape, TextBlock } from ... .
  • ➕ Added a sample demonstrating generating a PDF file for a Diagram, in the projects/pdf subdirectory. The sample is at minimalPDF.
  • 🛠 Fix for AnimationTriggers erroneously starting when dragging and dropping Parts from another Diagram or Palette.
  • 🛠 Fix for LinkingTool not deselecting other parts when a new link is created.

• v2.1.5

  January 03, 2020

  🔄 Changes for 2.1.5

  • ➕ Added VirtualizedPacked sample, which demonstrates a custom layout for large graphs of nested groups, defined in VirtualizedPackedLayout.ts. (Source is TS only)
  • 🛠 Fixed an issue where setting a node key reference in either a node or link via GraphLinksModel.setGroupKeyForNodeData, GraphLinksModel.setFromKeyForLinkData, or GraphLinksModel.setToKeyForLinkData could fail to resolve if the node did not yet exist. This issue did not exist during typical model loading.
  • 🛠 Fixed a regression since 2.1.1 with Diagram.clear failing to clear internal Parts lists (like Diagram.nodes).

• v2.1.4

  December 16, 2019

  🔄 Changes for 2.1.4

  • ➕ Added Link.computeAdjusting to conditionally change the value of Link.adjusting used. As a new default, links will use the adjusting value Link.End during animation. Link.computeAdjusting can be overriden to change this behavior.
  • ➕ Added Geometry.getPointAlongPath, Geometry.getAngleAlongPath, and Geometry.getFractionForPoint. These methods can be used to find a point or angle for a given fractional distance along a Geometry's path, or to find the fractional distance along the Geometry's path given a nearby point.
  • ✅ Setting GraphObject.segmentIndex to NaN, which was previously an error, will now treat the entire link path as the segment for the purpose of GraphObject.segmentFraction. This allows for getting fractional distances along the entire link.
  • 🛠 Fix for object picking during Diagram's InitialLayoutCompleted DiagramEvent.
  • 🛠 Fixed a bug in GoCloudStorage where a null defaultModel would fail.
  • 🛠 Fixed a bug in Panel.graduatedValueForPoint in cases where the main shape was a diagonal line and the provided point didn't fall on the line.

• v2.1.3

  December 04, 2019

  🔄 Changes for 2.1.3

  • 🛠 Fixed a regression (that started in 2.0.0) with AvoidsNodes links improperly re-routing when using the DraggingTool.
  • 🛠 Fixed a undo (redo) bug with AnimationTriggers that used location or position on Parts.
  • 👌 Improved routing of duplicate links that have Link.adjusting set to a value other than None and have more than the standard number of points in their route.

• v2.1.2

  November 20, 2019

  🔄 Changes for 2.1.2

  • 🛠 Fixed a regression in 2.1.1 with the timing of InitialAnimationStarting that would prevent custom initial animations.
  • ✅ CTRL + Mouse-wheel will still stop the event from bubbling, even if CommandHandler.canIncreaseZoom or CommandHandler.canDecreaseZoom are false. These are potentially false if a Diagram.minScale or Diagram.maxScale are set. This change stops the entire page from accidentally zooming during a zoom-wheel operation.
  • 🛠 Fixed a measuring bug with Link Geometry when the Link is smaller than the Link.toShortLength or Link.fromShortLength.

• v2.1.1

  November 18, 2019

  🔄 Changes for 2.1.1

  • 🛠 Fixed updating of Adornments when there are Bindings from Model.modelData and that shared object has been modified by calling Model.set.
  • 👌 Improved performance when replacing Diagram.model when cleaning up the old model, which had infrequently resulted in obscure warnings in debug mode about Node.isTreeLeaf.
  • 🛠 Fixes for loading Models with serialized EnumValues.
  • 🐎 Performance improvements for concurrent animations.
  • 🛠 Fixes for consistency of animation state. This includes modifying when  AnimationStarting  and  InitialAnimationStarting  are called, and fixes when default animations are stopped and another is immediately started, such as when loading a new model in the middle of animation.
  • 🛠 Fixed Model.fromJson loading models with serialized EnumValues.
  • 👌 Improved showing non-default cursors when dragging between diagrams.
  • 🛠 Fixed the operation of Diagram.handlesDragDropForTopLevelParts when dragging on the elements of a Group.
  • 🛠 Fixed a bug where Diagram.scrollHorizontalLineChange and Diagram.scrollVerticalLineChange would not affect scrolling size in some browsers.
  • 🛠 Fixed a bug where some AvoidsNodes Links would not route properly in nested groups.

• v2.1.0

  November 06, 2019

  GoJS 2.1

  🆕 New Animation Capabilities

  GoJS 2.1 contains a number of new features to animate different components of your Diagram.

   

  👀 See the Intro page on Animation and the Custom Animation extension for more details and examples.

  • 🆕 New default GoJS animation "fades up", instead of animating Node locations. Added AnimationManager.initialAnimationStyle to control this behavior. Here is an example of:
    • (top) The new initial animation, the Diagram position animating upwards and Diagram opacity animating from 0 to 1.
    • (middle) A custom "zoom in" animation, animating Diagram scale, which is demonstrated in the new State Chart sample,
    • (bottom) AnimationManager.initialAnimationStyle set to AnimationManager.AnimateLocations to perform the GoJS 2.0 and previous style of animation. The Data Visualization sample uses this option.
  • ➕ Added  "InitialAnimationStarting"  DiagramEvent to more easily customize initial animations. See AnimationManager.initialAnimationStyle for details.
  • 🆕 New class: AnimationTrigger. These describe how to automatically animate a property on a GraphObject when it changes value.
  • 🆕 New class: Animation. This class lets you declaratively setup custom animations, with options for indefinite animations.
  • 🆕 New AnimationManager options, including the ability to define custom animation effects to animate with AnimationManager.defineAnimationEffect
  • 🆕 New Animation samples and samples modified to use new Animation features:
    • Custom Animation -  New Extension:  Demonstrating a number of Node creation/deletion animations, linking animations, and more.
    • Tree Load Animation -  New Sample:  recursive animation upon model load.
    • Flowchart - In the Palette only, initial animation is disabled in favor of a custom fade-in animation.
    • State Chart - Initial animation is disabled in favor of a custom zoom fade-in animation.
    • Data Visualization - Nodes now move using an AnimationTrigger.
    • Kitten Monitor - Kittens now move using an AnimationTrigger.
    • Process Flow - An indefinite Animation of the Links' strokeDashArray.
    • Shop Floor Monitor - Link color changes now use an AnimationTrigger.

  👌 Improved Support For Data Synchronization

  GoJS 2.1 contains some new methods to ease integration of GoJS diagrams in applications that maintain their own data, particularly React apps.

  👀 See the Intro page on using GoJS with React and the gojs-react example project for details and examples. Also see gojs-react, a package containing React Components for GoJS Diagrams, Palettes, and Overviews.

  • 🆕 New method: Model.toIncrementalData. This method outputs an IncrementalData object containing changes that occurred within a Transaction, similar to the existing method, Model.toIncrementalJson. It can be used to keep outside data synchronized with the GoJS model.
  • 🆕 New methods: Model.mergeNodeDataArray and GraphLinksModel.mergeLinkDataArray. These methods are used to merge outside data changes into the GoJS model.
  • 🆕 New method: Model.cloneDeep. This method can be used to make a deep copy of an object, which may be useful to ensure GoJS doesn't share references with outside state. It is also used within Model.toIncrementalData to ensure IncrementalData's list of modified objects won't contain references to the model's data objects.

  Other Changes for 2.1.0:

  • ➕ Added DoubleTreeLayout to the extensions and extensionsTS directories. This is now used by both the Double Tree and Double Tree JSON samples.
  • ⚡️ Updated the sequencing of "ChangingSelection" and "ChangedSelection" DiagramEvents to be outside of transactions for commands and tools. Exceptions include "ChangingSelection" being called during "Drag" and "Linking" operations when drag-copying or inserting a link. With "ChangedSelection" occuring after a transaction completes, any changes will be complete and can be used in the listener.
  • ✅ CommandHandler.zoomToFit now animates by default.
  • 👌 Improved the ContextMenuTool.defaultTouchContextMenu's "Paste" command to use the ContextMenuTool.mouseDownPoint rather than the Diagram.lastInput's InputEvent.documentPoint.
  • ➕ Added new property, Diagram.opacity. This may be useful for fade-in/out animations, or visual indication of a disabled Diagram.
  • ➕ Added new method, Diagram.findLinkForKey, which will look for a link corresponding to a model's link data object's unique key. This will only return a link when using a GraphLinksModel with GraphLinksModel.linkKeyProperty set to a non-empty string.
  • ✅ Model.applyIncrementalJson now throws an error if model properties (eg. nodeKeyProperty) included in the JSON don't match the existing model. This check only includes properties included in the output from Model.toIncrementalJson.
  • ➕ Added new methods, Picture.reload, which reloads a Picture source in case the file on the server has changed, and Picture.redraw which redraws the picture, and can be useful to update the Picture if the source is backed by an HTML Canvas or HTML Video Element.
  • ➕ Added new samples:
    • SVG Data URL - Export SVG with Base64 hrefs instead of the Picture.source URL

• v2.0.21

  December 04, 2019

  🔄 Changes for 2.0.21

  • 🛠 Fixed a regression (that started in 2.0.0) with AvoidsNodes links improperly re-routing when using the DraggingTool.
  • 👌 Improved routing of duplicate links that have Link.adjusting set to a value other than None and have more than the standard number of points in their route.
