- // a Win32-style cursor resource file must be directly included in apps,
- // otherwise hiding the cursor will cause mouse-motion data to never be
- // received.
- //
- // Here's the lengthy explanation:
- //
- // There are two ways to hide a cursor in WinRT/UWP apps.
- // Both involve setting the WinRT CoreWindow's (which is somewhat analogous
- // to a Win32 HWND) 'PointerCursor' property.
- //
- // The first way to hide a cursor sets PointerCursor to nullptr. This
- // is, arguably, the easiest to implement for an app. It does have an
- // unfortunate side-effect: it'll prevent mouse-motion events from being
- // sent to the app (via CoreWindow).
- //
- // The second way to hide a cursor sets PointerCursor to a transparent
- // cursor. This allows mouse-motion events to be sent to the app, but is
- // more difficult to set up, as:
- // 1. WinRT/UWP, while providing a few stock cursors, does not provide
- // a completely transparent cursor.
- // 2. WinRT/UWP allows apps to provide custom-built cursors, but *ONLY*
- // if they are linked directly inside the app, via Win32-style
- // cursor resource files. APIs to create cursors at runtime are
- // not provided to apps, and attempting to link-to or use Win32
- // cursor-creation APIs could cause an app to fail Windows Store
- // certification.
- //
- // SDL can use either means of hiding the cursor. It provides a Win32-style
- // set of cursor resource files in its source distribution, inside
- // src/main/winrt/. If those files are linked to an SDL-for-WinRT/UWP app
- // (by including them in a MSVC project, for example), SDL will attempt to
- // use those, if and when the cursor is hidden via SDL APIs. If those
- // files are not linked in, SDL will attempt to hide the cursor via the
- // 'set PointerCursor to nullptr' means (which, if you recall, causes
- // mouse-motion data to NOT be sent to the app!).
- //
- // Tech notes:
- // - SDL's blank cursor resource uses a resource ID of 5000.
- // - SDL's cursor resources consist of the following two files:
- // - src/main/winrt/SDL2-WinRTResource_BlankCursor.cur -- cursor pixel data
- // - src/main/winrt/SDL2-WinRTResources.rc -- declares the cursor resource, and its ID (of 5000)
- //
-
- const unsigned int win32CursorResourceID = 5000;
- CoreCursor ^ blankCursor = ref new CoreCursor(CoreCursorType::Custom, win32CursorResourceID);
-
- // Set 'PointerCursor' to 'blankCursor' in a way that shouldn't throw
- // an exception if the app hasn't loaded that resource.
- ABI::Windows::UI::Core::ICoreCursor * iblankCursor = reinterpret_cast<ABI::Windows::UI::Core::ICoreCursor *>(blankCursor);
- ABI::Windows::UI::Core::ICoreWindow * icoreWindow = reinterpret_cast<ABI::Windows::UI::Core::ICoreWindow *>(coreWindow);
- HRESULT hr = icoreWindow->put_PointerCursor(iblankCursor);
- if (FAILED(hr)) {
- // The app doesn't contain the cursor resource, or some other error
- // occurred. Just use the other, but mouse-motion-preventing, means of
