Changes from JGraph 5.9.2.0 to JGraph 5.10.0.0 beta 1
===================================================== This release makes a number of, currently, experimental changes that mean it is not assured to be stable and that Java 1.3 can no longer be used. The double buffering support has been developed so that the buffered image is retained constantly making panning and scroll much faster and reducing the time taken to start a drag or resize in a large graph. The option to request that graphics hardware acceleration is used for the double buffering is available, but switched off by default. Also added is the concept of a buffered overlay image for transparent drawing on the foreground without having to redraw the static buffered graph. Changes from JGraph 5.9.1.0 to JGraph 5.9.2.0 ============================================= In addition to supporting an image on the background, a Component may now be drawn as the JGraph background for applications such as mapping. Some performance improvements have been made in the GraphLayoutCache relating to making cells invisible. In the model there have also been performance improvements around the functionality that removes cells. Changes from JGraph 5.9.0.0 to JGraph 5.9.1.0 ============================================= This release adds support for a background image that is refreshed during all necessary drag, resize, and model change events. Changes from JGraph 5.8.3.1 to JGraph 5.9.0.0 ============================================= Double buffering in JGraph previously consisted of off-screen buffers created in the root handles and size handles to buffer drag-and-resize previews on a per-case basis. However, the review buffered the entire graph image, so recreating the buffer on each operation was expensive in CPU terms. The off-screen buffer and off-screen graphics that are the graphics object of the buffer have been moved to the JGraph class. Also, the cachedLabelBounds and cachedExtraLabelBounds variables in EdgeView were never set (since getLabelBounds() and getExtraLabelBounds() were never called) and have been removed. Changes from JGraph 5.8.3.0 to JGraph 5.8.3.1 ============================================= A bug has been fixed where removing the user object did not action correctly. This has been fixed with an additional check in handleAttributes() in DefaultGraphModel. Also added is the getInsertionOffset() hook in GraphTransferHandler to enable positioning of cloned cells without copying the entire importData() method. Finally, a possible NPE in EdgeRenderer.getLabelPosition() has been enclosed in all the necessary null checks. Changes from JGraph 5.8.0.0 to JGraph 5.8.1.0 ============================================= Serialization of the WeakHashMap in the GraphLayoutCache has been resolved by adding custom write and read methods. Scaling the graph now is centered correctly and a new setScale method is available to zoom to a custom point. The edgeLabelMovable switch was added to the JGraph class to allow dragging of edge labels to be optionally disabled. There were a number of other minor bug fixes. Changes from JGraph 5.7.4.8 to JGraph 5.8.0.0 ============================================= The graph variable in EdgeRenderer has been replaced with a weak reference to ensure that static edge renderers release their reference to the current graph when all other objects do. Also, an example showing the use of a custom cell view factory and an example showing a selection model being synchronized between a graph and a tree were added to the examples package. Changes from JGraph 5.7.4.6 to JGraph 5.7.4.8 ============================================= This release adds the PREVIEW_EDGE_GROUP global switch to the GraphContext class, which makes the preview of edge with children optional. A CompoundVertexView example has been added to GraphEd to allow groups to be resized independently of their children (thanks Jerry). The graphics object in JGraph.getImage is manually disposed of to clean up resources quicker. Changes from JGraph 5.7.4.5 to JGraph 5.7.4.6 ============================================= A bug fix to a performance improvement made to the default graph model in 5.7.4.5 was required. Fixed ports that connected to floating ports were connecting to the wrong perimeter position on the floating port, this is now resolved. The "port magic" functionality that moves ports to attempt to straighten edges was incorrectly using the mouse position, it now no longer does so. Changes from JGraph 5.7.4.4 to JGraph 5.7.4.5 ============================================= A number of performance improvements were made in specific areas, mostly related to lazy instantiation and correct sizing of collections. addPort() was added to DefaultGraphCell to make creating ports easier. hiddenMapping in the GraphLayoutCache is now a WeakHashMap to avoid any possible memory leaks when cells are deleted. Also, in the GraphLayoutCache a helper method, removeViewLocalAttribute(), assists in the process of removing view local attributes and copying them into the model if required. A version of getPortViewAt with a custom tolerance was added to the JGraph class. Changes from JGraph 5.7.4.3 to JGraph 5.7.4.4 ============================================= Fixes occasional wrong index when adding new control points to edges, fixes selection check uses cell view in mouse handle, adds marquee handler as an optional serializable field to JGraph and the listener list in the layout cache is no longer transient. GraphEd adds new hooks for subclassers and new examples for serialization and XML encoding have been added to the commercial version. Changes from JGraph 5.7.4.2 to JGraph 5.7.4.3 ============================================= A number of changes were made to resolve various serialization issues. The use of transient modifiers was reviewed throughout the code. A problem were undos of cuts of groups could behave incorrectly was corrected. Various hooks for the example code were added. Changes from JGraph 5.7.4.1 to JGraph 5.7.4.2 ============================================= Fixes an issue with artifacts being left on the display when cells are dragged. Changes from JGraph 5.7.4 to JGraph 5.7.4.1 =========================================== An automatic resizing feature has been added so the graph expands as you drag out of the bottom or right-hand edges of a scroll pane. An appropriate flag, autoResizeGraph, to toggle the functionality have been added to the JGraph. A bug in the new collapse/expand example, GraphEdX, was fixed. The JGraph User Manual has received a number of corrections and the sections on XML encoding, image and SVG export and use in a headless environment have been improved. Changes from JGraph 5.7.3.1 to JGraph 5.7.4 =========================================== The DefaultCellViewFactory is now Serializable, so serializing the main part of the core should work correctly. Some example code from JGraph Layout Pro has been moved into the new GraphEdX example, this includes an XML encoding/ decoding example and how to create collapsible groups of cells. The image creation utility method in JGraph has been changed to use print instead of paint to draw graphics, this make certain server-side operations easier and more efficient. Also, a number of minor bugs have been fixed. Changes from JGraph 5.7.3 to JGraph 5.7.3.1 =========================================== The release fixes a critical bug whereby the initialisation ordering of certain static variables was not deterministic and could caused editing to always fail. Changes from JGraph 5.7.2 to JGraph 5.7.3 ========================================= Adds helper methods, fixes problems in headless environments, allows combined insert/removes/edits in DefaultGraphModel, adds switch to disable port magic. Changes from JGraph 5.7.1 to JGraph 5.7.2 ========================================= Fixes handling of connectable attribute for edges, sizeable- & moveable axis for groups. Fixes bugs for group translation and sizing, makes cloneCells more stable and fixes the label position for non-loops with multiple points. Changes from JGraph 5.7 to JGraph 5.7.1 ======================================= Fixes a bug in the attribute map cloning for extra label positions, adds a new helper method to collapse/expand cells, adds automatic resizing and moving of parent cells on collapse and switches to (not) show hidden cells on changes. Changes from JGraph 5.6.3 to JGraph 5.7 ======================================= The routing interface has changed so that the routing methods now return a list of points instead of accepting a list of points as a parameter. The routing of loops has been separated from the non-loop implementation for the default case so that it is easier to create a new routing implementation and inherit the default loop routing algorithm. Children cells moved as part of a collapsed group now are moved when the parent cell is, if required, using the movesChildrenOnExpand flag. Changes from JGraph 5.6.2.1 to JGraph 5.6.3 =========================================== The default vertex and port renderers kept references to the last graph used and this meant that removed JGraph instances could have a static memory footprint. The edge renderer still needs to be removed, however. Edges may now be painted with zero width, so you only see the label. The tolerance in JGraph.getNextViewAt is now scaled according to the current zoom value. Changes from JGraph 5.6.2 to JGraph 5.6.2.1 =========================================== Fixed critical bug in attribute map undo. Changes from JGraph 5.6.1 to JGraph 5.6.2 ========================================== Added User Manual to commercial distribution. Changes from JGraph 5.6 to JGraph 5.6.1 ========================================== getSelectionCellAt was added as a utility method to JGraph and returns the first selected cell whose bounds the parameter point lies within. The moves-into-group functionality has been corrected so it is based on whether the cells bounds is fully within the bounds of the group cell. Extra labels can now be cloned using ctrl-drag and deleted using shift and mouse press. A bounds cloning bug in JGraph.getCellBounds that caused cells to have a large height occasionally was fixed. getPerimeterPoint for an EdgeView now returns the center of the edge to make edge to edge connection easier. A number of other bugs were also fixed. Changes from JGraph 5.5.3 to JGraph 5.6 ========================================== A number of improvements have been made to the expand and collapse functionality. When a group is collapsed edges connecting to now-hidden vertices _visually_ attach to the perimeter point of the first visible parent group. Expanding the group shows the true state of connections again. It is now possible to connect edges directly to other edges. A large number of other bug fixes and functionality improvements were also made, see the ChangeLog for more details. Changes from JGraph 5.5.2 to JGraph 5.5.3: ========================================== The main JGraph class now has switches named moveIntoGroups and moveOutOfGroups that enable drag and drop of cells in and out of group cells. The getImage method was added to make the creation of images of JGraphs easier. A selection of helper methods were added and a number of minor bugs fixed. GraphModel.getValue was added and DefaultGraphModel.getUserObject deprecated. Changes from JGraph 5.5.1 to JGraph 5.5.2: ========================================== Adds a series of constructors and hooks to ease customization, fixes port floating for loops, adds encoding hooks to the default graph model, fixes auto-selection in the examples, adds hooks for vertex rendering and fixes a bug related to finding default ports with overlapping cells. Changes from JGraph 5.5 to JGraph 5.5.1: ========================================== This release makes a number of performance and memory footprint improvements, in particular, in relation to edges. A number of hooks have been added to make it possible to disable various functionality to obtain performance improvements. Various examples and documents were added to the purchased version. Also, a number of minor bugs were fixed and code tidy-ups performed. Changes from JGraph 5.4.7 to JGraph 5.5: ========================================== valueForCellChanged() has been added to the GraphModel interface to enable changing the value of the cell without performing typecasts. Edge labels that cross into negative co-ordinate space are moved into back into the visible area and in-place editing cannot now occur off the screen. Labels on self-references can now be moved. Various casts and type checks were added and various minor bugs fixed. Changes from JGraph 5.4.6 to JGraph 5.4.7: ========================================== Another review of the javadocs was made on the frozen 5.4.x API. Various changes were made to resolve issues with edges whose source and target are ports on the same vertex. Labels on such edges can now be moved and the routing functionality has been corrected. PortView.getLocation now has an additional parameter to support these changes, but no methods have been removed from the API. Changes from JGraph 5.4.5 to JGraph 5.4.6: ========================================== Since the JGraph API has been frozen in the 5.4.x series for stability, the first review of many of the javadocs was undertaken. All warnings were removed and various corrections and updates made. A divide by zero bug was fixed where the label position of an edge is calculated. If the source and target ports were the same port the zero length between the ports went into a calculation as the divisor. This was changed to simply return the label position as being on the port. The helper method GraphLayoutCache.createNestedMap was added and AbstractCellView changed so that it clones cell attributes in the refresh method. Changes from JGraph 5.4.4 to JGraph 5.4.5: ========================================== Fixes major bugs in edge handle for correct handling of model callbacks and placement of labels on scaled graphs, initial label bounds for extra labels, adds a helper method to JGraph and fixes the DefaultEdge.clone method.

Changes from JGraph 1.0.7 to 2.0 ================================ This release has a new API with new features. The get an overview of the most important changes and how they affect your code you should read the "New Features" and "Upgrading from 1.0.x" chapters. New Features: ------------- * Cell Visiblity: The GraphView, which is now called GraphLayoutCache offers a set of methods to show/hide cells, namely the setVisible method. This method fully supports undo/redo and in contrast to the earlier implementation using the visible attribute, this implementation does not allocate memory for invisible cells in a cache. The GraphLayoutCache contains built-in functions to automatically show edges between visible cells. When inserting and editing cells in a partial view, that is, one that does not show all cells of the model, then you should use the GraphLayoutCache's insert and edit method to allow the view to make the cells automatically visible (this way, the cell becomes visible in the view where is was inserted. The view (aka. cache) can be set up to insert new edges automatically in all views where the source and target ports are visible. Use the following GraphLayoutCache members to control automatic display: - showAllEdgesForVisibleVertices: Show edges on insert or change if their source and target vertex is visible - showEdgesOnShow: Show edges if their source and target vertex is displayed - hideEdgesOnHide: Hide edges if their source and target vertex is hidden - hideEdgesOnBecomeInvisible: Hide edges if their source and target becomes invisible (for example after removal) These members are set to true by default. Note: This feature allows to implement collapse/expand of groups. * View-Local Attributes: In the 1.0.x version, the GraphModel decided if it was an attribute store by use of the isAttributeStore method. In 2.0.x, it is the view who decides which attributes are view-local and which are global. Also, the edit method can now be called with a single attribute map that uses cells as the keys. The GraphLayoutCache provides a hook for subclassers, namely the createLocalEdit method to implement attribute splitting. The CellView's implementation was changed to override the global attributes with the view-local ones for. To enable this feature the code must use the GraphLayoutCache's edit, insert and remove methods instead of the model's. The view analyzes these method arguments, and extracts the view-local attributes before updating the model for the change. Note: This new feature allows more fine-grained control of view-local and global attributes. By removing the isAttributeStore and isOrdered methods it is not any more required that the model is aware of this feature. The ROUTING and POINTS attributes should be kept at the same location. Tip: Use GraphLayoutCache.rememberCellViews to control if view-local attributes should be remembered for hidden cells. * Edge Routing & Self References: A new attribute ROUTING was added that is interpreted by the EdgeView. The values for this key must implement the Edge.Routing interface, which extends the Serializable interface. The GraphConstants class provides a static instance ROUTING_SIMPLE of the DefaultEdge.DefaultRouting class. As the name implies this is the default implementation of the Routing interface. It allows simple routing and handles self-references. * Smaller Command History: The command history does only store the actual change, resulting in a smaller command history. In earlier versions, the complete state of all changed cells and views was stored. API Changes: ------------ (Only the most important changes are listed below.) Removed Members: * GraphConstants.createPropertyMap * GraphModel.isOrdered * GraphModel.isAttributeStore * GraphConstants.is/setVisible * CellRenderer.supportsAttribute * AbstractCellView.isControlAttribute New members: * BasicGraphUI.is/setSnapSelectedView A view under mousepointer may be snapped to the grid lines or moved by a constant increment during a drag operation based on this value. * Edge.Routing * GraphConstants.ROUTING_SIMPLE * DefaultEdge.DefaultRouting class * GraphConstants.get/setRouting * GraphConstants.createAttributes This is a helper method that may be used to create an attribute map * GraphLayoutCache.reset, is/setVisible, partial, ordered * DefaultGraphModel.getSource/TargetVertex Static helper method that calls getParent(getSource/Target) on the model * GraphLayoutCache.hiddenSet Used to remember local attributes of visible cells * JGraph.VERSION (use JGraph -version) * VertexRenderer.paintSelectionBorder Provided for subclassers to control drawing the selection border * VertexRenderer.is/setHideGroups Controls whether groups are fully painted by the renderer * Provide a handleEditTrigger Hook in BasicGraphUI.MouseHandler Changes: * GraphView renamed to GraphLayoutCache In accordance with JTree.TreeLayoutCache * JGraph.get/setView renamed to JGraph.get/setGraphLayoutCache To reflect this change * JGraph.SnapSize renamed to Tolerance (including getter, setter etc.) * JGraph.convertValueToString support view-local values The CellView decides what label to display * DefaultGraphCell.setAttributes renamed to changeAttributes Setter and getter methods should be used for bean properties. * Port.add/remove renamed to Port.addEdge/removeEdge (see http://sourceforge.net/forum/forum.php?thread_id=773281&forum_id=140880) * GraphConstants.ARROW prefix added to arrow styles * GraphConstants.STYLE prefix added to line styles * getPerimterPoint method was moved to the renderer * GraphViewChange.getAttributeMap renamed to getAttributes * GraphModelChange.getStoredAttributeMap renamed to getPreviousAttributes * DefaultGraphModel.handlePropertyMap renamed to handleAttributes * importData may return false to signal sender to not remove cells (Override importDataImpl instead of importData in GraphTransferHandler) * DefaultGraphSelectionModel.isChildrenSelectable now supports a cell argument * GraphLayoutCache.toBack/toFront take cells as arguments * GraphModel.insert and edit Argument order unified Fixed bugs: ----------- * Rounding erros on large zoom levels removed: The BasicGraphUI.RootHandles implementation did not work property for large zoom levels. Thanks to Jenya for the patch! * The maximum number of edges to paint in live-preview is now MAXCELLS * EdgeHandle does now support the SHIFT-key for constrained moving * Added some accessor methods to BasicMarqueeHandler for subclassers * BasicGraphUI.PropertyChangeListener calls repaint after GraphLayoutCache change * JGraph.setGraphLayoutCache checks and updates the cache's model if necessary * Vertices are not removed when their last port is removed dynamically Groups are still automatically removed when their last child cell is removed * EdgeRenderer now cached the created Shape in the corresponding EdgeView * BasicGraphUI.isDescendant uses GraphModel interface to return its data * Live preview during real DND (only for JDK < 1.4.0, see BasicGraphUI line 28) * DefaultEdge.constructor offers user object und boolean (allows children) * JGraph.disconnectOnMove must check the CONNECTABLE/DISCONNECTABLE attributes * Vertex, Port and Edge may carry the CONNECTABLE/DISCONNECTABLE attributes * NPE on edge change when new the port was not visible in other view removed * Groups may contain ports (Concurrency side-effects in EdgeRenderer.createShape) * Cache the bounds property of groups and recompute on change of children only * GetBounds-Infinite-Loop solved by exluding childedges between childs to group * Propagate CellView.update to parent instead of child (bubble up) * TransferHandler now supports move and DnD across multiple views, models and JVMS * Clone edges when reconnected and the Control key is pressed * ExecutableGraphChange interface added to execute all changes in model (Delegation) Also the GraphLayoutCache's changes are executed and dispatched by the model * In-place editing from empty to non-empty content is incorrectly undone * Removed in-place manipulation of BOUNDS-attribute in SizeHandle and RootHandle * Changed execution order of compound edits: first model then args in-order * Use GraphModel interface in DefaultGraphModel.getRoots only (no typecast) * GraphLayoutCache.getMapping may return null (if cell is not visible) * GraphUndoManager.redo throws CannotRedoException instead of CannotUndoException * Handles.initOffscreen is protected instead of package private Other changes: -------------- * To-do list added: A new to-do list for JGraph was added. The list is intended for developers as a roadmap for additional features, examples and research activities. * Version Naming Changed: The new version naming uses Swiss cities, where each City denotes a major release of the API. This means, all JGraph 2.0.x are said to be based on the Geneva API. * New JGraphpad Administrator: Please welcome Van Woods as the new JGraphpad administrator! See http://sourceforge.net/forum/message.php?msg_id=1833812 * JGraphpad updated: JGraphpad ported to JGraph 2.0. Release date is later this week. * Examples updated: All example have been updated to use JGraph 2.0. Currently, the examples are only available for download. The CVS repository still contains the old code. * Website updated: Many minor changes and updates on the website. Main changes include an optional license fee and donate button, a new banner and some additional links in the showcase etc. Upgrading from 1.0.x: --------------------- Here is an example. Please note the following in the example below: => We use Cells as keys to create the nested map instead of CellViews => We use the GraphLayoutCache's edit method instead of the model's => The order of the edit/insert method's arguments has changed => We use graph.getLayoutCache instead of graph.getView * JGraph 1.0.x: if (!graph.getModel().isAttributeStore()) cells = getView().getMapping(cells); Map viewMap = new Hashtable(); for (int i = 0; i < cells.length; i++) viewMap.put(cells[i], GraphConstants.cloneMap(map)); if (graph.getModel().isAttributeStore()) graph.getModel().edit(null, viewMap, null, null); else graph.getView().edit(viewMap); * JGraph 2.0.x (Geneva Code): Map nested = new Hashtable(); for (int i = 0; i < cells.length; i++) nested.put(cells[i], GraphConstants.cloneMap(map)); graph.getGraphLayoutCache().edit(nested, null, null, null); |
