1 Changes from JGraph 5.9.1.0 to JGraph 5.9.2.0
2 =============================================
3
4 In addition to supporting an image on the background, a Component may now be
5 drawn as the JGraph background for applications such as mapping. Some
6 performance improvements have been made in the GraphLayoutCache relating to
7 making cells invisible. In the model there have also been performance
8 improvements around the functionality that removes cells.
9
10 Changes from JGraph 5.9.0.0 to JGraph 5.9.1.0
11 =============================================
12
13 This release adds support for a background image that is refreshed during
14 all necessary drag, resize, and model change events.
15
16 Changes from JGraph 5.8.3.1 to JGraph 5.9.0.0
17 =============================================
18
19 Double buffering in JGraph previously consisted of off-screen buffers created
20 in the root handles and size handles to buffer drag-and-resize previews on a
21 per-case basis. However, the review buffered the entire graph image, so
22 recreating the buffer on each operation was expensive in CPU terms. The
23 off-screen buffer and off-screen graphics that are the graphics object of
24 the buffer have been moved to the JGraph class. Also, the cachedLabelBounds
25 and cachedExtraLabelBounds variables in EdgeView were never set (since
26 getLabelBounds() and getExtraLabelBounds() were never called) and have been
27 removed.
28
29 Changes from JGraph 5.8.3.0 to JGraph 5.8.3.1
30 =============================================
31
32 A bug has been fixed where removing the user object did not action correctly.
33 This has been fixed with an additional check in handleAttributes() in
34 DefaultGraphModel. Also added is the getInsertionOffset() hook in
35 GraphTransferHandler to enable positioning of cloned cells without copying
36 the entire importData() method. Finally, a possible NPE
37 in EdgeRenderer.getLabelPosition() has been enclosed in all the necessary
38 null checks.
39
40 Changes from JGraph 5.8.0.0 to JGraph 5.8.1.0
41 =============================================
42
43 Serialization of the WeakHashMap in the GraphLayoutCache has been resolved
44 by adding custom write and read methods. Scaling the graph now is centered
45 correctly and a new setScale method is available to zoom to a custom point.
46 The edgeLabelMovable switch was added to the JGraph class to allow dragging
47 of edge labels to be optionally disabled. There were a number of other minor
48 bug fixes.
49
50 Changes from JGraph 5.7.4.8 to JGraph 5.8.0.0
51 =============================================
52
53 The graph variable in EdgeRenderer has been replaced with a weak reference
54 to ensure that static edge renderers release their reference to the current
55 graph when all other objects do. Also, an example showing the use of a custom
56 cell view factory and an example showing a selection model being synchronized
57 between a graph and a tree were added to the examples package.
58
59 Changes from JGraph 5.7.4.6 to JGraph 5.7.4.8
60 =============================================
61
62 This release adds the PREVIEW_EDGE_GROUP global switch to the GraphContext
63 class, which makes the preview of edge with children optional. A
64 CompoundVertexView example has been added to GraphEd to allow groups to be
65 resized independently of their children (thanks Jerry). The graphics object
66 in JGraph.getImage is manually disposed of to clean up resources quicker.
67
68 Changes from JGraph 5.7.4.5 to JGraph 5.7.4.6
69 =============================================
70
71 A bug fix to a performance improvement made to the default graph model in
72 5.7.4.5 was required. Fixed ports that connected to floating ports were
73 connecting to the wrong perimeter position on the floating port, this is
74 now resolved. The "port magic" functionality that moves ports to attempt
75 to straighten edges was incorrectly using the mouse position, it now no
76 longer does so.
77
78 Changes from JGraph 5.7.4.4 to JGraph 5.7.4.5
79 =============================================
80
81 A number of performance improvements were made in specific areas, mostly
82 related to lazy instantiation and correct sizing of collections. addPort()
83 was added to DefaultGraphCell to make creating ports easier. hiddenMapping
84 in the GraphLayoutCache is now a WeakHashMap to avoid any possible memory
85 leaks when cells are deleted. Also, in the GraphLayoutCache a helper method,
86 removeViewLocalAttribute(), assists in the process of removing view local
87 attributes and copying them into the model if required. A version of
88 getPortViewAt with a custom tolerance was added to the JGraph class.
89
90 Changes from JGraph 5.7.4.3 to JGraph 5.7.4.4
91 =============================================
92
93 Fixes occasional wrong index when adding new control points to edges, fixes
94 selection check uses cell view in mouse handle, adds marquee handler as an
95 optional serializable field to JGraph and the listener list in the layout cache
96 is no longer transient. GraphEd adds new hooks for subclassers and new examples
97 for serialization and XML encoding have been added to the commercial version.
98
99 Changes from JGraph 5.7.4.2 to JGraph 5.7.4.3
100 =============================================
101
102 A number of changes were made to resolve various serialization issues. The use
103 of transient modifiers was reviewed throughout the code. A problem were undos
104 of cuts of groups could behave incorrectly was corrected. Various hooks for
105 the example code were added.
106
107 Changes from JGraph 5.7.4.1 to JGraph 5.7.4.2
108 =============================================
109
110 Fixes an issue with artifacts being left on the display when cells are dragged.
111
112 Changes from JGraph 5.7.4 to JGraph 5.7.4.1
113 ===========================================
114
115 An automatic resizing feature has been added so the graph expands as you drag
116 out of the bottom or right-hand edges of a scroll pane. An appropriate flag,
117 autoResizeGraph, to toggle the functionality have been added to the JGraph.
118 A bug in the new collapse/expand example, GraphEdX, was fixed. The JGraph
119 User Manual has received a number of corrections and the sections on XML
120 encoding, image and SVG export and use in a headless environment have been
121 improved.
122
123 Changes from JGraph 5.7.3.1 to JGraph 5.7.4
124 ===========================================
125
126 The DefaultCellViewFactory is now Serializable, so serializing the main part
127 of the core should work correctly. Some example code from JGraph Layout Pro
128 has been moved into the new GraphEdX example, this includes an XML encoding/
129 decoding example and how to create collapsible groups of cells. The image
130 creation utility method in JGraph has been changed to use print instead of
131 paint to draw graphics, this make certain server-side operations easier and
132 more efficient. Also, a number of minor bugs have been fixed.
133
134 Changes from JGraph 5.7.3 to JGraph 5.7.3.1
135 ===========================================
136
137 The release fixes a critical bug whereby the initialisation ordering of
138 certain static variables was not deterministic and could caused editing
139 to always fail.
140
141 Changes from JGraph 5.7.2 to JGraph 5.7.3
142 =========================================
143
144 Adds helper methods, fixes problems in headless environments, allows combined
145 insert/removes/edits in DefaultGraphModel, adds switch to disable port magic.
146
147 Changes from JGraph 5.7.1 to JGraph 5.7.2
148 =========================================
149
150 Fixes handling of connectable attribute for edges, sizeable- & moveable axis
151 for groups. Fixes bugs for group translation and sizing, makes cloneCells
152 more stable and fixes the label position for non-loops with multiple points.
153
154 Changes from JGraph 5.7 to JGraph 5.7.1
155 =======================================
156
157 Fixes a bug in the attribute map cloning for extra label positions, adds a new
158 helper method to collapse/expand cells, adds automatic resizing and moving of
159 parent cells on collapse and switches to (not) show hidden cells on changes.
160
161 Changes from JGraph 5.6.3 to JGraph 5.7
162 =======================================
163
164 The routing interface has changed so that the routing methods now return a list
165 of points instead of accepting a list of points as a parameter. The routing of
166 loops has been separated from the non-loop implementation for the default case
167 so that it is easier to create a new routing implementation and inherit the
168 default loop routing algorithm. Children cells moved as part of a collapsed
169 group now are moved when the parent cell is, if required, using the
170 movesChildrenOnExpand flag.
171
172 Changes from JGraph 5.6.2.1 to JGraph 5.6.3
173 ===========================================
174
175 The default vertex and port renderers kept references to the last graph used
176 and this meant that removed JGraph instances could have a static memory
177 footprint. The edge renderer still needs to be removed, however. Edges may
178 now be painted with zero width, so you only see the label. The tolerance in
179 JGraph.getNextViewAt is now scaled according to the current zoom value.
180
181 Changes from JGraph 5.6.2 to JGraph 5.6.2.1
182 ===========================================
183
184 Fixed critical bug in attribute map undo.
185
186 Changes from JGraph 5.6.1 to JGraph 5.6.2
187 ==========================================
188
189 Added User Manual to commercial distribution.
190
191 Changes from JGraph 5.6 to JGraph 5.6.1
192 ==========================================
193
194 getSelectionCellAt was added as a utility method to JGraph and returns the first
195 selected cell whose bounds the parameter point lies within. The moves-into-group
196 functionality has been corrected so it is based on whether the cells bounds
197 is fully within the bounds of the group cell. Extra labels can now be cloned
198 using ctrl-drag and deleted using shift and mouse press. A bounds cloning bug
199 in JGraph.getCellBounds that caused cells to have a large height occasionally
200 was fixed. getPerimeterPoint for an EdgeView now returns the center of the
201 edge to make edge to edge connection easier. A number of other bugs were also
202 fixed.
203
204 Changes from JGraph 5.5.3 to JGraph 5.6
205 ==========================================
206
207 A number of improvements have been made to the expand and collapse
208 functionality. When a group is collapsed edges connecting to now-hidden
209 vertices _visually_ attach to the perimeter point of the first visible
210 parent group. Expanding the group shows the true state of connections again.
211 It is now possible to connect edges directly to other edges.
212 A large number of other bug fixes and functionality improvements were also
213 made, see the ChangeLog for more details.
214
215 Changes from JGraph 5.5.2 to JGraph 5.5.3:
216 ==========================================
217
218 The main JGraph class now has switches named moveIntoGroups and moveOutOfGroups
219 that enable drag and drop of cells in and out of group cells. The getImage
220 method was added to make the creation of images of JGraphs easier. A selection
221 of helper methods were added and a number of minor bugs fixed.
222 GraphModel.getValue was added and DefaultGraphModel.getUserObject deprecated.
223
224 Changes from JGraph 5.5.1 to JGraph 5.5.2:
225 ==========================================
226
227 Adds a series of constructors and hooks to ease customization, fixes port
228 floating for loops, adds encoding hooks to the default graph model, fixes
229 auto-selection in the examples, adds hooks for vertex rendering and fixes
230 a bug related to finding default ports with overlapping cells.
231
232 Changes from JGraph 5.5 to JGraph 5.5.1:
233 ==========================================
234
235 This release makes a number of performance and memory footprint improvements,
236 in particular, in relation to edges. A number of hooks have been added to make
237 it possible to disable various functionality to obtain performance
238 improvements. Various examples and documents were added to the purchased
239 version. Also, a number of minor bugs were fixed and code tidy-ups performed.
240
241 Changes from JGraph 5.4.7 to JGraph 5.5:
242 ==========================================
243
244 valueForCellChanged() has been added to the GraphModel interface to enable
245 changing the value of the cell without performing typecasts. Edge labels that
246 cross into negative co-ordinate space are moved into back into the visible area
247 and in-place editing cannot now occur off the screen. Labels on self-references
248 can now be moved. Various casts and type checks were added and various minor
249 bugs fixed.
250
251 Changes from JGraph 5.4.6 to JGraph 5.4.7:
252 ==========================================
253
254 Another review of the javadocs was made on the frozen 5.4.x API. Various
255 changes were made to resolve issues with edges whose source and target are
256 ports on the same vertex. Labels on such edges can now be moved and the
257 routing functionality has been corrected. PortView.getLocation now has an
258 additional parameter to support these changes, but no methods have been
259 removed from the API.
260
261 Changes from JGraph 5.4.5 to JGraph 5.4.6:
262 ==========================================
263
264 Since the JGraph API has been frozen in the 5.4.x series for stability,
265 the first review of many of the javadocs was undertaken. All warnings were
266 removed and various corrections and updates made. A divide by zero bug
267 was fixed where the label position of an edge is calculated. If the source
268 and target ports were the same port the zero length between the ports
269 went into a calculation as the divisor. This was changed to simply return
270 the label position as being on the port. The helper method
271 GraphLayoutCache.createNestedMap was added and AbstractCellView changed so
272 that it clones cell attributes in the refresh method.
273
274 Changes from JGraph 5.4.4 to JGraph 5.4.5:
275 ==========================================
276
277 Fixes major bugs in edge handle for correct handling of model callbacks and
278 placement of labels on scaled graphs, initial label bounds for extra labels,
279 adds a helper method to JGraph and fixes the DefaultEdge.clone method.

481
482
483
484 Changes from JGraph 1.0.7 to 2.0
485 ================================
486
487 This release has a new API with new features. The get an overview of the
488 most important changes and how they affect your code you should read the
489 "New Features" and "Upgrading from 1.0.x" chapters.
490
491 New Features:
492 -------------
493
494 * Cell Visiblity:
495 The GraphView, which is now called GraphLayoutCache offers a set of methods
496 to show/hide cells, namely the setVisible method. This method fully supports
497 undo/redo and in contrast to the earlier implementation using the visible
498 attribute, this implementation does not allocate memory for invisible cells
499 in a cache. The GraphLayoutCache contains built-in functions to automatically
500 show edges between visible cells. When inserting and editing cells in a
501 partial view, that is, one that does not show all cells of the model, then
502 you should use the GraphLayoutCache's insert and edit method to allow the
503 view to make the cells automatically visible (this way, the cell becomes
504 visible in the view where is was inserted. The view (aka. cache) can be set
505 up to insert new edges automatically in all views where the source and target
506 ports are visible.
507 Use the following GraphLayoutCache members to control automatic display:
508 - showAllEdgesForVisibleVertices: Show edges on insert or change if their
509 source and target vertex is visible
510 - showEdgesOnShow: Show edges if their source and target vertex is displayed
511 - hideEdgesOnHide: Hide edges if their source and target vertex is hidden
512 - hideEdgesOnBecomeInvisible: Hide edges if their source and target becomes
513 invisible (for example after removal)
514 These members are set to true by default.
515 Note: This feature allows to implement collapse/expand of groups.
516
517 * View-Local Attributes:
518 In the 1.0.x version, the GraphModel decided if it was an attribute store by
519 use of the isAttributeStore method. In 2.0.x, it is the view who decides
520 which attributes are view-local and which are global. Also, the edit method
521 can now be called with a single attribute map that uses cells as the keys.
522 The GraphLayoutCache provides a hook for subclassers, namely the
523 createLocalEdit method to implement attribute splitting. The CellView's
524 implementation was changed to override the global attributes with the
525 view-local ones for. To enable this feature the code must use the
526 GraphLayoutCache's edit, insert and remove methods instead of the model's.
527 The view analyzes these method arguments, and extracts the view-local
528 attributes before updating the model for the change.
529 Note: This new feature allows more fine-grained control of view-local and
530 global attributes. By removing the isAttributeStore and isOrdered methods
531 it is not any more required that the model is aware of this feature. The
532 ROUTING and POINTS attributes should be kept at the same location.
533 Tip: Use GraphLayoutCache.rememberCellViews to control if view-local
534 attributes should be remembered for hidden cells.
535
536 * Edge Routing & Self References:
537 A new attribute ROUTING was added that is interpreted by the EdgeView. The
538 values for this key must implement the Edge.Routing interface, which extends
539 the Serializable interface. The GraphConstants class provides a static instance
540 ROUTING_SIMPLE of the DefaultEdge.DefaultRouting class. As the name implies this
541 is the default implementation of the Routing interface. It allows simple routing
542 and handles self-references.
543
544 * Smaller Command History:
545 The command history does only store the actual change, resulting in a smaller
546 command history. In earlier versions, the complete state of all changed cells
547 and views was stored.
548
549

608
609 Fixed bugs:
610 -----------
611
612 * Rounding erros on large zoom levels removed:
613 The BasicGraphUI.RootHandles implementation did not work property for
614 large zoom levels. Thanks to Jenya for the patch!
615 * The maximum number of edges to paint in live-preview is now MAXCELLS
616 * EdgeHandle does now support the SHIFT-key for constrained moving
617 * Added some accessor methods to BasicMarqueeHandler for subclassers
618 * BasicGraphUI.PropertyChangeListener calls repaint after GraphLayoutCache change
619 * JGraph.setGraphLayoutCache checks and updates the cache's model if necessary
620 * Vertices are not removed when their last port is removed dynamically
621 Groups are still automatically removed when their last child cell is removed
622 * EdgeRenderer now cached the created Shape in the corresponding EdgeView
623 * BasicGraphUI.isDescendant uses GraphModel interface to return its data
624 * Live preview during real DND (only for JDK < 1.4.0, see BasicGraphUI line 28)
625 * DefaultEdge.constructor offers user object und boolean (allows children)
626 * JGraph.disconnectOnMove must check the CONNECTABLE/DISCONNECTABLE attributes
627 * Vertex, Port and Edge may carry the CONNECTABLE/DISCONNECTABLE attributes
628 * NPE on edge change when new the port was not visible in other view removed
629 * Groups may contain ports (Concurrency side-effects in EdgeRenderer.createShape)
630 * Cache the bounds property of groups and recompute on change of children only
631 * GetBounds-Infinite-Loop solved by exluding childedges between childs to group
632 * Propagate CellView.update to parent instead of child (bubble up)
633 * TransferHandler now supports move and DnD across multiple views, models and JVMS
634 * Clone edges when reconnected and the Control key is pressed
635 * ExecutableGraphChange interface added to execute all changes in model (Delegation)

644
645
646 Other changes:
647 --------------
648
649 * To-do list added:
650 A new to-do list for JGraph was added. The list is intended for developers
651 as a roadmap for additional features, examples and research activities.
652 * Version Naming Changed:
653 The new version naming uses Swiss cities, where each City denotes a major
654 release of the API. This means, all JGraph 2.0.x are said to be based on
655 the Geneva API.
656 * New JGraphpad Administrator:
657 Please welcome Van Woods as the new JGraphpad administrator!
658 See http://sourceforge.net/forum/message.php?msg_id=1833812
659 * JGraphpad updated:
660 JGraphpad ported to JGraph 2.0. Release date is later this week.
661 * Examples updated:
662 All example have been updated to use JGraph 2.0. Currently, the examples are
663 only available for download. The CVS repository still contains the old code.
664 * Website updated:
665 Many minor changes and updates on the website. Main changes include an
666 optional license fee and donate button, a new banner and some additional
667 links in the showcase etc.
668
669
670 Upgrading from 1.0.x:
671 ---------------------
672
673 Here is an example. Please note the following in the example below:
674
675 => We use Cells as keys to create the nested map instead of CellViews
676 => We use the GraphLayoutCache's edit method instead of the model's
677 => The order of the edit/insert method's arguments has changed
678 => We use graph.getLayoutCache instead of graph.getView
679
680 * JGraph 1.0.x:
681
682 if (!graph.getModel().isAttributeStore())
683 cells = getView().getMapping(cells);
684 Map viewMap = new Hashtable();
685 for (int i = 0; i < cells.length; i++)
686 viewMap.put(cells[i], GraphConstants.cloneMap(map));
687 if (graph.getModel().isAttributeStore())
688 graph.getModel().edit(null, viewMap, null, null);
689 else
690 graph.getView().edit(viewMap);
691
692 * JGraph 2.0.x (Geneva Code):
693
694 Map nested = new Hashtable();
695 for (int i = 0; i < cells.length; i++)
696 nested.put(cells[i], GraphConstants.cloneMap(map));
697 graph.getGraphLayoutCache().edit(nested, null, null, null);
