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.
