Use this prompt in Copilot CLI:
|
|
|
|
Migrate the legacy Qt5/C++11 desktop application to Qt6/C++23.
|
|
|
|
Requirements:
|
|
- Read the legacy source project from ${PROJECT_DIR}
|
|
- Write the migrated project into qt6-after/qt6-migrated-benchmark
|
|
- Do not modify the legacy source tree in place
|
|
- Update CMake from Qt5 to Qt6
|
|
- Keep Core, Gui, and Widgets explicitly linked
|
|
- Replace QRegExp with QRegularExpression
|
|
- Replace QDesktopWidget / QApplication::desktop() usage with QScreen-based Qt6 APIs
|
|
- Remove legacy QTextCodec usage and use modern Qt6-safe text handling
|
|
- Modernize old SIGNAL/SLOT syntax to function-pointer connect syntax
|
|
- Replace legacy null pointer literals with nullptr
|
|
- Preserve the .ui and .qrc integration
|
|
- Preserve application behavior
|
|
- Upgrade the project from C++11 to C++23
|
|
- For every code change inside a method, add at least three tests covering the changed behavior
|
|
- Place all generated tests in qt6-after/qt6-migrated-benchmark/tests
|
|
- Update CMake so the migrated application and all tests build successfully with CTest
|
|
- Keep the test file naming compatible with repository policy checks
|
|
- Briefly explain each migration change
