Covered by existing QImage conversion functions.
QtWin::createMask() is equivalent to image.convertToFormat(QImage::Format_Mono).invertPixels().toHBITMAP().
Covered by existing QRegion conversion functions.
Simple wrapper around _com_error::ErrorMessage(). Duplicated in QtCore and a few other places. Can't add direct QDebug overload due to HRESULT being a typedef long, but functionality already covered by QSystemError::NativeError and qt_error_string() (API is in itself in need of some cleanups, but that's another story).
Giant mapping from error codes to literal error name, .e.g 0x80004004 to "E_ABORT". Only used internally in WinExtras, not in any other Qt module or on code on GitHub.
Functionality around the Windows theme accent color. Concept exists on other platforms too, should be exposed in a cross platform manner, e.g. a new QPalette role or platform theme property.
Functionality to opt out of the Windows desktop peek feature. The feature is disabled by default in Windows 10. Fringe use-case that can be solved by calling DwmSetWindowAttribute with DWMWA_EXCLUDED_FROM_PEEK directly.
Functionality to opt out of showing a preview of the window when hovering over it in the Window task bar. Fringe use-case that can be solved by calling DwmSetWindowAttribute with DWMWA_DISALLOW_PEEK directly.
Windows 7 feature, no longer supported in Windows 10.
Extends the glass frame into the client area of the specified window. Similar functionality exists as private APIs on macOS. Should be replaced by cross platform QWindow API to control the relationship between the client area and the non-client area (frame/titlebar). QTBUG-94010
Introduced in Qt 6.0 (for a module that was not part of Qt 6). Fringe use-case that can be solved by calling DwmSetWindowAttribute with DWMWA_NCRENDERING_POLICY directly. Should be reconsidered and aligned with cross platform solution to extendFrameIntoClientArea.
Deprecated as of Windows 8. If needed or still relevant, it should be aligned with similar features on e.g. macOS, perhaps as QWindow flags/API.
Minimal wrapper around SetCurrentProcessExplicitAppUserModelID. Can be replaced in user code by SetCurrentProcessExplicitAppUserModelID(id.toStdWString().c_str()); Not used in any Qt module.
Documented as "You do not usually need to call this function". Shouldn't be needed, should be automatically handled based on a QWindow's window state.
API around ITaskbarList to activate the tab button of a window programatically without activating the associated Window. Fringe use-case. Not used in any Qt module or by code on GitHub.
API around ITaskbarList to manage additional toolbar buttons. Associated to a window, so would seem a better API to control the window tab-bar visibility of the window directly. Fringe use-case. Not used in any Qt module or by code on GitHub.
Should expect people who interact with native API wrappers like these to work at the QWindow level.
Should expect people who interact with native API wrappers like these to to expose the relevant functionality from C++ to QML.
Windows specific mapping to QMimeData mimetypes. Overlaps with similar use-case for macOS. Should have cross platform api. QTBUG-93632
Ability to add entries to the Windows taskbar right-click menu. Overlaps with use-case handled by QMenu:: setAsDockMenu() on macOS. Should be exposed as cross platform API, e.g. QGuiApplication::setMenu(). QTBUG-94007
Manage taskbar overlay icon and progress. Useful use-case for other platforms (https://github.com/sindresorhus/DockProgress), should be cross platform API. Moved to native interface for QWindowsWindow if needed. QTBUG-94009 and QTBUG-94008
Used to add additional controls to the windows task bar peek menu. Not used in any Qt module or in code on GitHub.
