* New upstream release.
1 Changes from JGraph beta 1 to JGraph beta 2
2 =============================================================
4 This release is a bug fix release resolving all issues reported with the Beta 1
5 release to date.
8 Changes from JGraph to JGraph beta 1
9 =====================================================
11 This release makes a number of, currently, experimental changes that mean it
12 is not assured to be stable and that Java 1.3 can no longer be used.
13 The double buffering support has been developed so that the buffered image
14 is retained constantly making panning and scroll much faster and reducing
15 the time taken to start a drag or resize in a large graph. The option to
16 request that graphics hardware acceleration is used for the double buffering
17 is available, but switched off by default. Also added is the concept of a
18 buffered overlay image for transparent drawing on the foreground without
19 having to redraw the static buffered graph.
21 Changes from JGraph to JGraph
22 =============================================
24 In addition to supporting an image on the background, a Component may now be
25 drawn as the JGraph background for applications such as mapping. Some
26 performance improvements have been made in the GraphLayoutCache relating to
27 making cells invisible. In the model there have also been performance
28 improvements around the functionality that removes cells.
30 Changes from JGraph to JGraph
31 =============================================
33 This release adds support for a background image that is refreshed during
34 all necessary drag, resize, and model change events.
36 Changes from JGraph to JGraph
37 =============================================
39 Double buffering in JGraph previously consisted of off-screen buffers created
40 in the root handles and size handles to buffer drag-and-resize previews on a
41 per-case basis. However, the review buffered the entire graph image, so
42 recreating the buffer on each operation was expensive in CPU terms. The
43 off-screen buffer and off-screen graphics that are the graphics object of
44 the buffer have been moved to the JGraph class. Also, the cachedLabelBounds
45 and cachedExtraLabelBounds variables in EdgeView were never set (since
46 getLabelBounds() and getExtraLabelBounds() were never called) and have been
47 removed.
49 Changes from JGraph to JGraph
50 =============================================
52 A bug has been fixed where removing the user object did not action correctly.
53 This has been fixed with an additional check in handleAttributes() in
54 DefaultGraphModel. Also added is the getInsertionOffset() hook in
55 GraphTransferHandler to enable positioning of cloned cells without copying
56 the entire importData() method. Finally, a possible NPE
57 in EdgeRenderer.getLabelPosition() has been enclosed in all the necessary
58 null checks.
60 Changes from JGraph to JGraph
61 =============================================
63 Serialization of the WeakHashMap in the GraphLayoutCache has been resolved
64 by adding custom write and read methods. Scaling the graph now is centered
65 correctly and a new setScale method is available to zoom to a custom point.
66 The edgeLabelMovable switch was added to the JGraph class to allow dragging
67 of edge labels to be optionally disabled. There were a number of other minor
68 bug fixes.
70 Changes from JGraph to JGraph
71 =============================================
73 The graph variable in EdgeRenderer has been replaced with a weak reference
74 to ensure that static edge renderers release their reference to the current
75 graph when all other objects do. Also, an example showing the use of a custom
76 cell view factory and an example showing a selection model being synchronized
77 between a graph and a tree were added to the examples package.
79 Changes from JGraph to JGraph
80 =============================================
82 This release adds the PREVIEW_EDGE_GROUP global switch to the GraphContext
83 class, which makes the preview of edge with children optional. A
84 CompoundVertexView example has been added to GraphEd to allow groups to be
85 resized independently of their children (thanks Jerry). The graphics object
86 in JGraph.getImage is manually disposed of to clean up resources quicker.
88 Changes from JGraph to JGraph
89 =============================================
91 A bug fix to a performance improvement made to the default graph model in
92 was required. Fixed ports that connected to floating ports were
93 connecting to the wrong perimeter position on the floating port, this is
94 now resolved. The "port magic" functionality that moves ports to attempt
95 to straighten edges was incorrectly using the mouse position, it now no
96 longer does so.
98 Changes from JGraph to JGraph
99 =============================================
101 A number of performance improvements were made in specific areas, mostly
102 related to lazy instantiation and correct sizing of collections. addPort()
103 was added to DefaultGraphCell to make creating ports easier. hiddenMapping
104 in the GraphLayoutCache is now a WeakHashMap to avoid any possible memory
105 leaks when cells are deleted. Also, in the GraphLayoutCache a helper method,
106 removeViewLocalAttribute(), assists in the process of removing view local
107 attributes and copying them into the model if required. A version of
108 getPortViewAt with a custom tolerance was added to the JGraph class.
110 Changes from JGraph to JGraph
111 =============================================
113 Fixes occasional wrong index when adding new control points to edges, fixes
114 selection check uses cell view in mouse handle, adds marquee handler as an
115 optional serializable field to JGraph and the listener list in the layout cache
116 is no longer transient. GraphEd adds new hooks for subclassers and new examples
117 for serialization and XML encoding have been added to the commercial version.
119 Changes from JGraph to JGraph
120 =============================================
122 A number of changes were made to resolve various serialization issues. The use
123 of transient modifiers was reviewed throughout the code. A problem were undos
124 of cuts of groups could behave incorrectly was corrected. Various hooks for
125 the example code were added.
127 Changes from JGraph to JGraph
128 =============================================
130 Fixes an issue with artifacts being left on the display when cells are dragged.
132 Changes from JGraph 5.7.4 to JGraph
133 ===========================================
135 An automatic resizing feature has been added so the graph expands as you drag
136 out of the bottom or right-hand edges of a scroll pane. An appropriate flag,
137 autoResizeGraph, to toggle the functionality have been added to the JGraph.
138 A bug in the new collapse/expand example, GraphEdX, was fixed. The JGraph
139 User Manual has received a number of corrections and the sections on XML
140 encoding, image and SVG export and use in a headless environment have been
141 improved.
143 Changes from JGraph to JGraph 5.7.4
144 ===========================================
146 The DefaultCellViewFactory is now Serializable, so serializing the main part
147 of the core should work correctly. Some example code from JGraph Layout Pro
148 has been moved into the new GraphEdX example, this includes an XML encoding/
149 decoding example and how to create collapsible groups of cells. The image
150 creation utility method in JGraph has been changed to use print instead of
151 paint to draw graphics, this make certain server-side operations easier and
152 more efficient. Also, a number of minor bugs have been fixed.
154 Changes from JGraph 5.7.3 to JGraph
155 ===========================================
157 The release fixes a critical bug whereby the initialisation ordering of
158 certain static variables was not deterministic and could caused editing
159 to always fail.
161 Changes from JGraph 5.7.2 to JGraph 5.7.3
162 =========================================
164 Adds helper methods, fixes problems in headless environments, allows combined
165 insert/removes/edits in DefaultGraphModel, adds switch to disable port magic.
167 Changes from JGraph 5.7.1 to JGraph 5.7.2
168 =========================================
170 Fixes handling of connectable attribute for edges, sizeable- & moveable axis
171 for groups. Fixes bugs for group translation and sizing, makes cloneCells
172 more stable and fixes the label position for non-loops with multiple points.
174 Changes from JGraph 5.7 to JGraph 5.7.1
175 =======================================
177 Fixes a bug in the attribute map cloning for extra label positions, adds a new
178 helper method to collapse/expand cells, adds automatic resizing and moving of
179 parent cells on collapse and switches to (not) show hidden cells on changes.
181 Changes from JGraph 5.6.3 to JGraph 5.7
182 =======================================
184 The routing interface has changed so that the routing methods now return a list
185 of points instead of accepting a list of points as a parameter. The routing of
186 loops has been separated from the non-loop implementation for the default case
187 so that it is easier to create a new routing implementation and inherit the
188 default loop routing algorithm. Children cells moved as part of a collapsed
189 group now are moved when the parent cell is, if required, using the
190 movesChildrenOnExpand flag.
192 Changes from JGraph to JGraph 5.6.3
193 ===========================================
195 The default vertex and port renderers kept references to the last graph used
196 and this meant that removed JGraph instances could have a static memory
197 footprint. The edge renderer still needs to be removed, however. Edges may
198 now be painted with zero width, so you only see the label. The tolerance in
199 JGraph.getNextViewAt is now scaled according to the current zoom value.
201 Changes from JGraph 5.6.2 to JGraph
202 ===========================================
204 Fixed critical bug in attribute map undo.
206 Changes from JGraph 5.6.1 to JGraph 5.6.2
207 ==========================================
209 Added User Manual to commercial distribution.
211 Changes from JGraph 5.6 to JGraph 5.6.1
212 ==========================================
214 getSelectionCellAt was added as a utility method to JGraph and returns the first
215 selected cell whose bounds the parameter point lies within. The moves-into-group
216 functionality has been corrected so it is based on whether the cells bounds
217 is fully within the bounds of the group cell. Extra labels can now be cloned
218 using ctrl-drag and deleted using shift and mouse press. A bounds cloning bug
219 in JGraph.getCellBounds that caused cells to have a large height occasionally
220 was fixed. getPerimeterPoint for an EdgeView now returns the center of the
221 edge to make edge to edge connection easier. A number of other bugs were also
222 fixed.
224 Changes from JGraph 5.5.3 to JGraph 5.6
225 ==========================================
227 A number of improvements have been made to the expand and collapse
228 functionality. When a group is collapsed edges connecting to now-hidden
229 vertices _visually_ attach to the perimeter point of the first visible
230 parent group. Expanding the group shows the true state of connections again.
231 It is now possible to connect edges directly to other edges.
232 A large number of other bug fixes and functionality improvements were also
233 made, see the ChangeLog for more details.
235 Changes from JGraph 5.5.2 to JGraph 5.5.3:
236 ==========================================
238 The main JGraph class now has switches named moveIntoGroups and moveOutOfGroups
239 that enable drag and drop of cells in and out of group cells. The getImage
240 method was added to make the creation of images of JGraphs easier. A selection
241 of helper methods were added and a number of minor bugs fixed.
242 GraphModel.getValue was added and DefaultGraphModel.getUserObject deprecated.
244 Changes from JGraph 5.5.1 to JGraph 5.5.2:
245 ==========================================
247 Adds a series of constructors and hooks to ease customization, fixes port
248 floating for loops, adds encoding hooks to the default graph model, fixes
249 auto-selection in the examples, adds hooks for vertex rendering and fixes
250 a bug related to finding default ports with overlapping cells.
252 Changes from JGraph 5.5 to JGraph 5.5.1:
253 ==========================================
255 This release makes a number of performance and memory footprint improvements,
256 in particular, in relation to edges. A number of hooks have been added to make
257 it possible to disable various functionality to obtain performance
258 improvements. Various examples and documents were added to the purchased
259 version. Also, a number of minor bugs were fixed and code tidy-ups performed.
261 Changes from JGraph 5.4.7 to JGraph 5.5:
262 ==========================================
264 valueForCellChanged() has been added to the GraphModel interface to enable
265 changing the value of the cell without performing typecasts. Edge labels that
266 cross into negative co-ordinate space are moved into back into the visible area
267 and in-place editing cannot now occur off the screen. Labels on self-references
268 can now be moved. Various casts and type checks were added and various minor
269 bugs fixed.
271 Changes from JGraph 5.4.6 to JGraph 5.4.7:
272 ==========================================
274 Another review of the javadocs was made on the frozen 5.4.x API. Various
275 changes were made to resolve issues with edges whose source and target are
276 ports on the same vertex. Labels on such edges can now be moved and the
277 routing functionality has been corrected. PortView.getLocation now has an
278 additional parameter to support these changes, but no methods have been
279 removed from the API.
281 Changes from JGraph 5.4.5 to JGraph 5.4.6:
282 ==========================================
284 Since the JGraph API has been frozen in the 5.4.x series for stability,
285 the first review of many of the javadocs was undertaken. All warnings were
286 removed and various corrections and updates made. A divide by zero bug
287 was fixed where the label position of an edge is calculated. If the source
288 and target ports were the same port the zero length between the ports
289 went into a calculation as the divisor. This was changed to simply return
290 the label position as being on the port. The helper method
291 GraphLayoutCache.createNestedMap was added and AbstractCellView changed so
292 that it clones cell attributes in the refresh method.
294 Changes from JGraph 5.4.4 to JGraph 5.4.5:
295 ==========================================
297 Fixes major bugs in edge handle for correct handling of model callbacks and
298 placement of labels on scaled graphs, initial label bounds for extra labels,
299 adds a helper method to JGraph and fixes the DefaultEdge.clone method.

504 Changes from JGraph 1.0.7 to 2.0
505 ================================
507 This release has a new API with new features. The get an overview of the
508 most important changes and how they affect your code you should read the
509 "New Features" and "Upgrading from 1.0.x" chapters.
511 New Features:
512 -------------
514 * Cell Visiblity:
515 The GraphView, which is now called GraphLayoutCache offers a set of methods
516 to show/hide cells, namely the setVisible method. This method fully supports
517 undo/redo and in contrast to the earlier implementation using the visible
518 attribute, this implementation does not allocate memory for invisible cells
519 in a cache. The GraphLayoutCache contains built-in functions to automatically
520 show edges between visible cells. When inserting and editing cells in a
521 partial view, that is, one that does not show all cells of the model, then
522 you should use the GraphLayoutCache's insert and edit method to allow the
523 view to make the cells automatically visible (this way, the cell becomes
524 visible in the view where is was inserted. The view (aka. cache) can be set
525 up to insert new edges automatically in all views where the source and target
526 ports are visible.
527 Use the following GraphLayoutCache members to control automatic display:
528 - showAllEdgesForVisibleVertices: Show edges on insert or change if their
529 source and target vertex is visible
530 - showEdgesOnShow: Show edges if their source and target vertex is displayed
531 - hideEdgesOnHide: Hide edges if their source and target vertex is hidden
532 - hideEdgesOnBecomeInvisible: Hide edges if their source and target becomes
533 invisible (for example after removal)
534 These members are set to true by default.
535 Note: This feature allows to implement collapse/expand of groups.
537 * View-Local Attributes:
538 In the 1.0.x version, the GraphModel decided if it was an attribute store by
539 use of the isAttributeStore method. In 2.0.x, it is the view who decides
540 which attributes are view-local and which are global. Also, the edit method
541 can now be called with a single attribute map that uses cells as the keys.
542 The GraphLayoutCache provides a hook for subclassers, namely the
543 createLocalEdit method to implement attribute splitting. The CellView's
544 implementation was changed to override the global attributes with the
545 view-local ones for. To enable this feature the code must use the
546 GraphLayoutCache's edit, insert and remove methods instead of the model's.
547 The view analyzes these method arguments, and extracts the view-local
548 attributes before updating the model for the change.
549 Note: This new feature allows more fine-grained control of view-local and
550 global attributes. By removing the isAttributeStore and isOrdered methods
551 it is not any more required that the model is aware of this feature. The
552 ROUTING and POINTS attributes should be kept at the same location.
553 Tip: Use GraphLayoutCache.rememberCellViews to control if view-local
554 attributes should be remembered for hidden cells.
556 * Edge Routing & Self References:
557 A new attribute ROUTING was added that is interpreted by the EdgeView. The
558 values for this key must implement the Edge.Routing interface, which extends
559 the Serializable interface. The GraphConstants class provides a static instance
560 ROUTING_SIMPLE of the DefaultEdge.DefaultRouting class. As the name implies this
561 is the default implementation of the Routing interface. It allows simple routing
562 and handles self-references.
564 * Smaller Command History:
565 The command history does only store the actual change, resulting in a smaller
566 command history. In earlier versions, the complete state of all changed cells
567 and views was stored.
570 API Changes:
571 ------------

614 * Port.add/remove renamed to Port.addEdge/removeEdge
615 (see http://sourceforge.net/forum/forum.php?thread_id=773281&forum_id=140880)
616 * GraphConstants.ARROW prefix added to arrow styles
617 * GraphConstants.STYLE prefix added to line styles
618 * getPerimterPoint method was moved to the renderer
619 * GraphViewChange.getAttributeMap renamed to getAttributes
620 * GraphModelChange.getStoredAttributeMap renamed to getPreviousAttributes
621 * DefaultGraphModel.handlePropertyMap renamed to handleAttributes
622 * importData may return false to signal sender to not remove cells
623 (Override importDataImpl instead of importData in GraphTransferHandler)
624 * DefaultGraphSelectionModel.isChildrenSelectable now supports a cell argument
625 * GraphLayoutCache.toBack/toFront take cells as arguments
626 * GraphModel.insert and edit Argument order unified
629 Fixed bugs:
630 -----------
632 * Rounding erros on large zoom levels removed:
633 The BasicGraphUI.RootHandles implementation did not work property for
634 large zoom levels. Thanks to Jenya for the patch!
635 * The maximum number of edges to paint in live-preview is now MAXCELLS
636 * EdgeHandle does now support the SHIFT-key for constrained moving
637 * Added some accessor methods to BasicMarqueeHandler for subclassers
638 * BasicGraphUI.PropertyChangeListener calls repaint after GraphLayoutCache change
639 * JGraph.setGraphLayoutCache checks and updates the cache's model if necessary
640 * Vertices are not removed when their last port is removed dynamically
641 Groups are still automatically removed when their last child cell is removed
642 * EdgeRenderer now cached the created Shape in the corresponding EdgeView
643 * BasicGraphUI.isDescendant uses GraphModel interface to return its data
644 * Live preview during real DND (only for JDK < 1.4.0, see BasicGraphUI line 28)
645 * DefaultEdge.constructor offers user object und boolean (allows children)
646 * JGraph.disconnectOnMove must check the CONNECTABLE/DISCONNECTABLE attributes
647 * Vertex, Port and Edge may carry the CONNECTABLE/DISCONNECTABLE attributes
648 * NPE on edge change when new the port was not visible in other view removed
649 * Groups may contain ports (Concurrency side-effects in EdgeRenderer.createShape)
650 * Cache the bounds property of groups and recompute on change of children only
651 * GetBounds-Infinite-Loop solved by exluding childedges between childs to group
652 * Propagate CellView.update to parent instead of child (bubble up)
653 * TransferHandler now supports move and DnD across multiple views, models and JVMS
654 * Clone edges when reconnected and the Control key is pressed
655 * ExecutableGraphChange interface added to execute all changes in model (Delegation)
656 Also the GraphLayoutCache's changes are executed and dispatched by the model
657 * In-place editing from empty to non-empty content is incorrectly undone
658 * Removed in-place manipulation of BOUNDS-attribute in SizeHandle and RootHandle
659 * Changed execution order of compound edits: first model then args in-order
660 * Use GraphModel interface in DefaultGraphModel.getRoots only (no typecast)
661 * GraphLayoutCache.getMapping may return null (if cell is not visible)
662 * GraphUndoManager.redo throws CannotRedoException instead of CannotUndoException
663 * Handles.initOffscreen is protected instead of package private
666 Other changes:
667 --------------
669 * To-do list added:
670 A new to-do list for JGraph was added. The list is intended for developers
671 as a roadmap for additional features, examples and research activities.
672 * Version Naming Changed:
673 The new version naming uses Swiss cities, where each City denotes a major
674 release of the API. This means, all JGraph 2.0.x are said to be based on
675 the Geneva API.
676 * New JGraphpad Administrator:
677 Please welcome Van Woods as the new JGraphpad administrator!
678 See http://sourceforge.net/forum/message.php?msg_id=1833812
679 * JGraphpad updated:
680 JGraphpad ported to JGraph 2.0. Release date is later this week.
681 * Examples updated:
682 All example have been updated to use JGraph 2.0. Currently, the examples are
683 only available for download. The CVS repository still contains the old code.
684 * Website updated:
685 Many minor changes and updates on the website. Main changes include an
686 optional license fee and donate button, a new banner and some additional
687 links in the showcase etc.
690 Upgrading from 1.0.x:
691 ---------------------
693 Here is an example. Please note the following in the example below:
695 => We use Cells as keys to create the nested map instead of CellViews
696 => We use the GraphLayoutCache's edit method instead of the model's
697 => The order of the edit/insert method's arguments has changed
698 => We use graph.getLayoutCache instead of graph.getView
700 * JGraph 1.0.x:
702 if (!graph.getModel().isAttributeStore())
703 cells = getView().getMapping(cells);
704 Map viewMap = new Hashtable();
705 for (int i = 0; i < cells.length; i++)
706 viewMap.put(cells[i], GraphConstants.cloneMap(map));
707 if (graph.getModel().isAttributeStore())
708 graph.getModel().edit(null, viewMap, null, null);
709 else
710 graph.getView().edit(viewMap);
712 * JGraph 2.0.x (Geneva Code):
714 Map nested = new Hashtable();
715 for (int i = 0; i < cells.length; i++)
716 nested.put(cells[i], GraphConstants.cloneMap(map));
717 graph.getGraphLayoutCache().edit(nested, null, null, null);
