Qt6 Migration: Complete SituationMap module migration with comprehensive tests
Migration Summary: - Migrated 7 subdirectories: GraphicalObjects, Rubberbands, MathUtils, MapImpl, SymbologyImpl, Viewshed3D, and Common - Applied Qt6 API changes: QTouchEvent, Qt::MiddleButton, QFuture continuations - Updated ArcGIS SDK v300: include paths, identifyGraphicsOverlaysAsync() - Fixed QList/QVector unification issues in MathUtils - Replaced QSharedPointer::use_count() with isNull()/data() comparisons Test Coverage: - Created 6 new test files following check_pr_policies.py naming conventions - test_graphical_objects.cpp, test_rubberbands.cpp, test_mathutils.cpp - test_mapimpl.cpp, test_symbologyimpl.cpp, test_viewshed3d.cpp - All tests integrated into CMake and CTest - 42 SituationMap tests passing (695 total tests) Build Validation: - Docker build successful with Qt 6.10.2 via aqtinstall - Fixed LtsDataView dependency order in CMakeLists.txt - Fixed test paths to use absolute TESTS_DIR - Removed duplicate main() functions from test files Documentation: - Created MIGRATION_STATUS.md with detailed migration status - Created TEST_REPORT.md with comprehensive test coverage summary Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* @brief Tests für Qt6 API-Migrationen
|

*
|

* Tests verify that:
|

* 1. QStringView works correctly (replacing QStringRef)
|

* 2. std::list works correctly (replacing QLinkedList)
|
||||
* 3. QMultiMap works correctly (replacing QMap with multi-values)
|
||||
* 4. QFontMetricsF::horizontalAdvance() works (replacing width())
|
||||
* 5. QVariant::fromValue() works for custom types
|
||||
* 6. QXmlStreamWriter UTF-8 handling (no setCodec needed)
