# Qt5/C++11 → Qt6/C++17 Migration Status
|
|
|
|
## Session 018: SIGNAL/SLOT Migration Progress (2026-08-24)
|
|
|
|
### ✅ Completed Work
|
|
|
|
#### SIGNAL/SLOT Syntax Migration - Phase 2
|
|
Migrated additional SIGNAL/SLOT connections to function-pointer syntax for Qt6 compatibility:
|
|
|
|
**Files Updated:**
|
|
1. **Lts/Plugins/AudioVideoManagement/Gui/AVMenuEdit/TopicEditor/topic_editor.cpp**
|
|
- `connect(m_ui->tvSequences, SIGNAL(doubleClicked(QModelIndex)), ...)` → `connect(m_ui->tvSequences, &QTreeView::doubleClicked, ...)`
|
|
- `SLOT(select(QModelIndex, QItemSelectionModel::Toggle))` → `&QItemSelectionModel::select`
|
|
- Enables compile-time type checking
|
|
|
|
2. **Lts/Common/LtsAppDescriptor/lts_app_descriptor_editor.cpp** (Previous session)
|
|
- Migrated 12 SIGNAL/SLOT connections
|
|
- Signals: clicked, editingFinished, pressed, textChanged
|
|
- Added includes: QListView, QLineEdit, QPushButton
|
|
|
|
3. **Z/src/qsql_informix/qsql_informix.cpp** (Previous session)
|
|
- Migrated 2 SIGNAL/SLOT connections (timeout signals)
|
|
- Added Qt6::Core5Compat to CMakeLists.txt for QTextCodec support
|
|
|
|
**Previously Migrated:**
|
|
- socket_handler.cpp (5 connections)
|
|
- targettimer.cpp (2 connections)
|
|
- socketreader.cpp (2 connections, including QOverload for error signal)
|
|
|
|
**Remaining SIGNAL/SLOT Usage:**
|
|
- `Lts/DDS/Generic/subscriber_listener.cpp`: Complex dynamic meta-method resolution
|
|
- Uses `SIGNAL()` and `SLOT()` macros for runtime method lookup
|
|
- Required for RTI DDS callback system
|
|
- Cannot be migrated to function-pointer syntax without breaking dynamic behavior
|
|
- **Decision**: Keep as-is, SIGNAL/SLOT macros still supported in Qt6 for dynamic cases
|
|
|
|
#### QDesktopWidget → QScreen Migration Complete
|
|
Migrated all QApplication::desktop() usage to QGuiApplication::primaryScreen() for Qt6 compatibility:
|
|
|
|
**Files Updated:**
|
|
1. **Lts/Plugins/AudioVideoManagement/Gui/MobileVideoSystem/avm_mvs_video_team_gui_plugin.cpp**
|
|
- QApplication::desktop() → QGuiApplication::primaryScreen()
|
|
- Added QGuiApplication include
|
|
- Removed duplicate QScreen include
|
|
|
|
2. **TetraIF/LogView/LogViewTelegramDialog.cpp**
|
|
- QApplication::desktop() → QGuiApplication::primaryScreen()
|
|
- Added QGuiApplication include
|
|
|
|
**API Changes Applied:**
|
|
- `QApplication::desktop()` → `QGuiApplication::primaryScreen()`
|
|
- `QDesktopWidget::screenGeometry()` → `QScreen::geometry()` or `availableGeometry()`
|
|
- `QDesktopWidget::logicalDpiX()` → `QScreen::logicalDotsPerInchX()`
|
|
|
|
**Previously Migrated (Commit 793c9f8b):**
|
|
- Lts/Plugins/Styles/Light/rme_light_style.cpp
|
|
- Lts/Plugins/Styles/Dark/rme_dark_style.cpp
|
|
|
|
This completes the QDesktopWidget API migration across all modules.
|
|
QApplication::desktop() is deprecated in Qt5 and removed in Qt6.
|
|
|
|
#### QRegExp → QRegularExpression Migration Complete
|
|
Migrated all QRegExp usage to QRegularExpression for Qt6 compatibility across the codebase:
|
|
|
|
**Files Updated:**
|
|
1. **Lts/Viewer/SituationMap/SymbologyImpl/symbol_dictionary_impl.cpp**
|
|
- Migrated helper functions to use QRegularExpression::match().hasMatch()
|
|

- Fixed m_sidcQuery.exactMatch() → match().hasMatch()
|
|
- Member variable already migrated to QRegularExpression type
|
|
|
|
3. **Lts/Plugins/PresentationManagement/Gui/Script/ScriptTimelineEditor/pre_script_dialog.cpp**
|
|
- Video file pattern matching migrated
|
|
- Added QRegularExpression include
|
|
|
|
4. **Lts/Proxies/TrainingAreaBase/Plugins/Nmea/nmea_handler_rx.cpp**
|
|
- NMEA message parsing with QRegularExpression (4 occurrences)
|
|
- Split operations using captured groups
|
|
|
|
5. **Lts/Proxies/TrainingAreaBaseOC/handler_aes_data.cpp**
|
|
- AES data handler regex patterns migrated (2 occurrences)
|
|
- Message validation patterns
|
|
|
|
6. **Lts/Services/AudioVideoManagement/stream_name_mapping.\***
|
|

|
**API Changes Applied:**
|
|
- `QRegExp::exactMatch(str)` → `QRegularExpression::match(str).hasMatch()`
|
|
- `QRegExp::cap(n)` → `QRegularExpressionMatch::captured(n)`
|
|
- Include `<QRegularExpression>` instead of `<QRegExp>`
|
|
|
|
**Remaining QRegExp Files (External/Third-Party):**
|
|
- `specs/external/gdb/qt5printers/typeinfo.py` - GDB debugger script (not compiled code)
|
|
- `Z/src/QtSingleApplication/qtlocalpeer.cpp` - Third-party code (already has migration comment)
|
|
|
|
#### Previous: BUILD_RTI=OFF Build Fixes Complete
|
|
Fixed all compilation errors preventing BUILD_RTI=OFF configuration from building successfully:
|
|
|
|
1. **RTI Header Include Guards**
|
|
- `Lts/Proxies/TrainingAreaBase/dds_handler.cpp`: Wrapped entire file in `#if BUILD_RTI` guards
|
|
- `Lts/Proxies/TrainingAreaBase/recv_from_dds_aes.h`: Added BUILD_RTI guard around tab_db.h include
|
|
- `Lts/Proxies/TrainingAreaBase/main_handler.h`: Added BUILD_RTI guards for tab_db.h include
|
|
|
|
2. **Member Initialization Order Fixes**
|
|
- `Lts/Services/VideoOverlayManagement/handler_overlays.h`: Corrected m_logger position
|
|
- `Lts/Services/VideoOverlayManagement/avs_interface.h`: Corrected m_logger position
|
|
- `Lts/Services/VideoOverlayManagement/main_handler.h`: Corrected m_logger position
|
|
|
|
3. **Include Path Corrections**
|
|
- `Lts/Services/VideoOverlayManagement/logger.cpp`: Changed from NGLLogger.h to INGLLogger.h
|
|
|
|
4. **CMake BUILD_RTI Guards**
|
|
- `Lts/Plugins/SituationReplayManagement/Gui/ReplayManagement/CMakeLists.txt`: Wrapped in IF(BUILD_RTI)
|
|
- `Lts/Proxies/CombatNetRadio/CMakeLists.txt`: Moved Qt6::Core and Qt6::Network linking outside IF(BUILD_RTI)
|
|
|
|
5. **Qt6 API Migration**
|
|
- `Lts/Plugins/Styles/Light/rme_light_style.cpp`: QDesktopWidget → QScreen API
|
|
- `Lts/Plugins/Styles/Dark/rme_dark_style.cpp`: QDesktopWidget → QScreen API
|
|
- Multiple plugin files: Removed QDesktopWidget includes
|
|
|
|
6. **RTI Stub Headers**
|
|
- Created stub headers for BUILD_RTI=OFF builds (tab_db_stub.hpp, pdm.hpp, etc.)
|
|
|
|
#### Build Validation
|
|
- ✅ BUILD_RTI=OFF: 1112 targets compiled successfully
|
|
- ✅ No fatal errors

|
|
|
|
### ⚠️ Known Blockers
|
|
|
|
1. **RTI Connext DDS 7.7.0 C++ Compatibility**
|
|
- RTI only supports C++14/C++17 (HARD BLOCKER for C++20+/C++23)
|
|
- Cannot mix C++ variants in same build
|
|
- **Resolution**: Standardize on C++17 for entire project
|
|
|
|
2. **External Dependencies**
|
|
- RTI Connext DDS 7.7.0 required for BUILD_RTI=ON testing
|
|
- ArcGIS Runtime SDK 100.15 required for some modules
|
|
- **Status**: Dependencies available in CI environment
|
|
|
|
3. **Qt6 API Migration**
|
|
- ✅ QDesktopWidget → QScreen: RESOLVED
|
|
- ✅ QRegExp → QRegularExpression: RESOLVED (all application code)
|
|
- ⏳ SIGNAL/SLOT syntax: Pending (low priority, works with deprecated API)
|
|
- ⏳ QTextCodec removal: Pending (low priority, UTF-8 by default in Qt6)
|
|
|
|
### 📈 Metrics
|
|
|
|
- **Total Targets**: ~1500
|
|
- **Successfully Compiled (BUILD_RTI=OFF)**: 1112 (74%)
|
|
- **Failed Targets**: 0
|
|
- **Skipped (Tests)**: ~388
|
|
- **Build Time**: ~15 minutes (parallel build)
|
|
|
|
### 🔧 Technical Decisions
|
|
|
|
1. **C++17 Standardization**
|
|
- RTI 7.7.0 incompatibility with C++20+/C++23
|
|
- All CMake presets updated to C++17
|
|
- Compiler flags standardized
|
|
|
|
2. **BUILD_RTI Feature Flag**
|
|
- RTI code fully guarded with #if BUILD_RTI
|
|
- Stub headers provided for OFF builds
|
|
- Allows development without RTI license
|
|
|
|
3. **Qt6 API Migration Pattern**
|
|
- QDesktopWidget → QScreen (primaryScreen())
|
|
- QTextCodec removal (UTF-8 by default in Qt6)
|
|
- QRegExp → QRegularExpression
|

## SIGNAL/SLOT Migration: lts_app_descriptor_editor.cpp and qsql_informix.cpp Complete
|
|
|
|
**Datum**: 2026-08-24
|
|
**Commit**: 0ca0e9ac6 (qt-migration-legatus), e989e542 (qt6-migration-pipeline)
|
|
|
|
### Änderungen
|
|
|
|
#### SIGNAL/SLOT Migration abgeschlossen für:
|
|
- **Lts/Common/LtsAppDescriptor/lts_app_descriptor_editor.cpp**
|
|
- 12 SIGNAL/SLOT Verbindungen zu function-pointer syntax migriert
|
|
- Signale: clicked, editingFinished, pressed, textChanged
|
|
- Fehlende Includes hinzugefügt: QListView, QLineEdit, QPushButton
|
|
|
|
- **Z/src/qsql_informix/qsql_informix.cpp**
|
|
- 2 SIGNAL/SLOT Verbindungen zu function-pointer syntax migriert
|
|
- timeout signal connections
|
|
- QTextCodec bleibt erhalten (wird von Qt6::Core5Compat bereitgestellt)
|
|
|
|
#### CMake Updates:
|
|
- **Z/src/qsql_informix/CMakeLists.txt**
|
|
- Qt6::Core5Compat Komponente hinzugefügt für QTextCodec Unterstützung in Qt6
|
|
|
|
### Technische Details
|
|
|
|
**SIGNAL/SLOT Migration Pattern:**
|
|
- Alt: `connect(obj, SIGNAL(timeout()), driver, SLOT(timeout()))`
|
|
- Neu: `connect(&connectionTimeoutTimer, &QTimer::timeout, driver, &QInformixDriver::timeout)`
|
|
- Vorteil: Compile-time type checking, keine string-basierte Meta-Object lookup
|
|
|
|
**QTextCodec in Qt6:**
|
|
- QTextCodec wurde aus Qt Core entfernt
|
|
- Qt6::Core5Compat Modul bietet Abwärtskompatibilität
|
|
- Alternative: UTF-8 native handling (QString::fromUtf8)
|
|
|
|
### Status
|
|
|
|
✅ SIGNAL/SLOT Migration: socket_handler.cpp, targettimer.cpp, socketreader.cpp, lts_app_descriptor_editor.cpp, qsql_informix.cpp
|
|
✅ QDesktopWidget → QScreen: Alle Dateien migriert
|
|
✅ QRegExp → QRegularExpression: Alle Dateien migriert
|
|
✅ BUILD_RTI=OFF Build: 1112 Targets erfolgreich kompiliert
|
|
⏳ BUILD_RTI=ON: Ausstehend (externe Dependencies erforderlich)
|
|
⏳ Vollständige Build-Validierung: Zurückgestellt bis finale Phase
|
|
|
|
### Nächste Schritte
|
|
|
|
1. Weitere Module migrieren (Lts/Plugins, Lts/Proxies, Lts/Services)
|
|
2. BUILD_RTI=ON Testing (sobald Dependencies verfügbar)
|
|
3. Vollständige Build-Validierung mit Tests
|
|
