From 932c9c006f994ea7e3b2509f30a3a8d4fcaf3ea1 Mon Sep 17 00:00:00 2001 From: JavaZeroo-Bot <133958205+JavaZeroo-Bot@users.noreply.github.com> Date: Sat, 7 Nov 2026 15:19:01 +0800 Subject: [PATCH 1/7] feat(qt): add bounded selection auto-scroll across retained history While a left-drag selection is held outside the visible grid, a bounded Qt timer scrolls HistoryViewport by one row per tick and re-extends the selection to the edge source position. The default scrollbar, painted highlights and Copy all consume the same source range. Drag back inside, release, focus loss, hide, unrelated resize and session close stop the timer; no stale selection is revived. No new history/selection model or performance threshold is added. Add a formal test with two real fixed-ConPTY children: up/down bounded ticks (one row per tick), exact source copy through an injected writer, drag-back, release, focus-loss and session isolation. The existing scrollbar remains enabled in this test. --- .github/workflows/qt-cpp.yml | 6 +- CMakeLists.txt | 14 ++++ src/qt/autoscroll_test.cpp | 156 +++++++++++++++++++++++++++++++++++ src/qt/terminal_widget.hpp | 60 +++++++++++++- 4 files changed, 233 insertions(+), 3 deletions(-) create mode 100644 src/qt/autoscroll_test.cpp diff --git a/.github/workflows/qt-cpp.yml b/.github/workflows/qt-cpp.yml index 1ba19d1..be48083 100644 --- a/.github/workflows/qt-cpp.yml +++ b/.github/workflows/qt-cpp.yml @@ -42,7 +42,7 @@ jobs: "-DTERMFORGE_CONPTY_BACKEND_DIR=$dependencyRoot/conpty" ` "-DTERMFORGE_MSVC_RUNTIME_DIR=$dependencyRoot/crt" - name: Build Qt product and independent smoke - run: cmake --build build/qt-cpp --config Release --target termforge_qt_shell qt_cpp_shell_smoke qt_cpp_resize_smoke qt_unicode_input_test qt_unicode_render_test qt_terminal_modes_test qt_hidden_retention_test qt_history_navigation_test qt_selection_migration_test qt_find_test qt_scrollbar_size_test qt_clipboard_system_test --parallel 2 + run: cmake --build build/qt-cpp --config Release --target termforge_qt_shell qt_cpp_shell_smoke qt_cpp_resize_smoke qt_unicode_input_test qt_unicode_render_test qt_terminal_modes_test qt_hidden_retention_test qt_history_navigation_test qt_selection_migration_test qt_find_test qt_scrollbar_size_test qt_autoscroll_test qt_clipboard_system_test --parallel 2 - name: Record complete path-free runtime manifests run: | python tools/msvc_runtime.py manifest --directory build/qt-cpp/qt-bin/Release --executable termforge_qt_shell.exe @@ -67,6 +67,8 @@ jobs: if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE } python tools/msvc_runtime.py manifest --directory build/qt-cpp/qt-scrollbar-size-bin/Release --executable qt_scrollbar_size_test.exe if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE } + python tools/msvc_runtime.py manifest --directory build/qt-cpp/qt-autoscroll-bin/Release --executable qt_autoscroll_test.exe + if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE } python tools/msvc_runtime.py manifest --directory build/qt-cpp/qt-clipboard-bin/Release --executable qt_clipboard_system_test.exe if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE } - name: Preserve runtime file identities without binaries @@ -88,7 +90,7 @@ jobs: build/qt-cpp/qt-selection-bin/Release/runtime-manifest.json build/qt-cpp/qt-clipboard-bin/Release/runtime-manifest.json - name: Run Qt offscreen smoke in its owned Job - run: ctest --test-dir build/qt-cpp -C Release -R '^(qt_cpp_(shell|resize)|qt_unicode_input|qt_unicode_render|qt_terminal_modes(_retained)?|qt_hidden_retention|qt_history_navigation|qt_selection_migration|qt_find|qt_scrollbar_size)$' --no-tests=error --verbose + run: ctest --test-dir build/qt-cpp -C Release -R '^(qt_cpp_(shell|resize)|qt_unicode_input|qt_unicode_render|qt_terminal_modes(_retained)?|qt_hidden_retention|qt_history_navigation|qt_selection_migration|qt_find|qt_scrollbar_size|qt_autoscroll)$' --no-tests=error --verbose - name: Run hosted-only Qt system clipboard copy run: python src/qt/run_smoke.py build/qt-cpp/qt-clipboard-bin/Release/qt_clipboard_system_test.exe --hosted-copy - name: Run hosted Windows QPA product-writer clipboard copy diff --git a/CMakeLists.txt b/CMakeLists.txt index b20848f..62170f9 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -832,6 +832,20 @@ if(TERMFORGE_BUILD_QT_SHELL) "${PROJECT_SOURCE_DIR}/src/qt/run_smoke.py" "$") set_tests_properties(qt_find PROPERTIES TIMEOUT 45 ENVIRONMENT "QT_QPA_PLATFORM=offscreen") + add_executable(qt_autoscroll_test src/qt/autoscroll_test.cpp) + set_target_properties(qt_autoscroll_test PROPERTIES + RUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/qt-autoscroll-bin/$") + termforge_qt_entry(qt_autoscroll_test) + target_link_libraries(qt_autoscroll_test PRIVATE Qt6::Test) + add_custom_command(TARGET qt_autoscroll_test POST_BUILD + COMMAND "${CMAKE_COMMAND}" -E copy_if_different + "$" + "$/platforms/" + VERBATIM) + add_test(NAME qt_autoscroll COMMAND "${Python3_EXECUTABLE}" + "${PROJECT_SOURCE_DIR}/src/qt/run_smoke.py" "$") + set_tests_properties(qt_autoscroll PROPERTIES TIMEOUT 45 + ENVIRONMENT "QT_QPA_PLATFORM=offscreen") add_executable(qt_scrollbar_size_test src/qt/scrollbar_size_test.cpp) set_target_properties(qt_scrollbar_size_test PROPERTIES RUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/qt-scrollbar-size-bin/$") diff --git a/src/qt/autoscroll_test.cpp b/src/qt/autoscroll_test.cpp new file mode 100644 index 0000000..b283ebb --- /dev/null +++ b/src/qt/autoscroll_test.cpp @@ -0,0 +1,156 @@ +// Formal Qt bounded selection auto-scroll across retained history.
