From a0029111fd05aef2280652cace9b6119e942f05e Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 9 Jun 2026 04:21:00 +0000 Subject: [PATCH 1/4] Persist "Group multiplicities / role names" class diagram option (#16) The class diagram layout option "Group multiplicities / role names" was not stored in the layout file, so the setting was lost whenever a model was reopened. It now defaults to enabled for class diagrams and is saved to and restored from the layout file. Changes: - Add a "groupmultiplicityrolenames" layout tag and write/read it in DiagramOptions#saveOptions/#loadOptions, guarded by a new layout version (14) for backward compatibility with older layout files. - Default the option to true for class diagrams (ClassDiagramOptions). - Make MultiplicityRolenameWrapper mirror the actual option value instead of blindly toggling on every change, and initialize its grouping state from the option, so a loaded/default value is honored. - Suppress grouping while a layout is being restored (reusing the existing isLoadingLayout flag, now set around layout loading in DiagramView) so restored label positions are not overwritten. Add DiagramOptionsPersistenceTest covering the save/load round-trip, the default value, the layout-version bump and backward compatibility with pre-v14 layout files. https://claude.ai/code/session_01A85dAvTAvi2oWkGZH6REEq --- NEWS | 2 + .../gui/views/diagrams/DiagramOptions.java | 6 +- .../use/gui/views/diagrams/DiagramView.java | 38 ++- .../classdiagram/ClassDiagramOptions.java | 5 + .../elements/MultiplicityRolenameWrapper.java | 40 ++- .../org/tzi/use/gui/xmlparser/LayoutTags.java | 1 + .../DiagramOptionsPersistenceTest.java | 250 ++++++++++++++++++ 7 files changed, 321 insertions(+), 21 deletions(-) create mode 100644 use-gui/src/test/java/org/tzi/use/gui/views/diagrams/DiagramOptionsPersistenceTest.java diff --git a/NEWS b/NEWS index 95c0f3365..6bc587bcf 100644 --- a/NEWS +++ b/NEWS @@ -3,6 +3,8 @@ Please see the file `README' for a description of how to report bugs. ** Changes between version 7.1.0 and X.X.X * USE now supports data types +* [GUI] The class diagram option "Group multiplicities / role names" is now + saved in the layout file and is enabled by default for class diagrams (#16) ** Changes between version 5.2.0 and 6.0.0 * New OCL complexity plugin diff --git a/use-gui/src/main/java/org/tzi/use/gui/views/diagrams/DiagramOptions.java b/use-gui/src/main/java/org/tzi/use/gui/views/diagrams/DiagramOptions.java index 344de5cd9..a81ff36f2 100644 --- a/use-gui/src/main/java/org/tzi/use/gui/views/diagrams/DiagramOptions.java +++ b/use-gui/src/main/java/org/tzi/use/gui/views/diagrams/DiagramOptions.java @@ -38,7 +38,7 @@ public abstract class DiagramOptions { /** * The current version number of the layout information */ - public static int XML_LAYOUT_VERSION = 13;
