WinRT
=====
This port allows SDL applications to run on Microsoft's platforms that require
use of "Windows Runtime", aka. "WinRT", APIs. Microsoft may, in some cases,
refer to them as either "Windows Store", or for Windows 10, "UWP" apps.
In the past, SDL has supported Windows RT 8.x, Windows Phone, etc, but in
modern times this port is focused on UWP apps, which run on Windows 10,
and modern Xbox consoles.
Requirements
------------
* Microsoft Visual C++ (aka Visual Studio) 2019.
- Free, "Community" or "Express" editions may be used, so long as they
include support for either "Windows Store" or "Windows Phone" apps.
"Express" versions marked as supporting "Windows Desktop" development
typically do not include support for creating WinRT apps, to note.
(The "Community" editions of Visual C++ do, however, support both
desktop/Win32 and WinRT development).
* A valid Microsoft account - This requirement is not imposed by SDL, but
rather by Microsoft's Visual C++ toolchain. This is required to launch or
debug apps.
Status
------
Here is a rough list of what works, and what doesn't:
* What works:
* compilation via Visual C++ 2019.
* compile-time platform detection for SDL programs. The C/C++ #define,
`__WINRT__`, will be set to 1 (by SDL) when compiling for WinRT.
* GPU-accelerated 2D rendering, via SDL_Renderer.
* OpenGL ES 2, via the ANGLE library (included separately from SDL)
* software rendering, via either SDL_Surface (optionally in conjunction with
SDL_GetWindowSurface() and SDL_UpdateWindowSurface()) or via the
SDL_Renderer APIs
* threads
* timers (via SDL_GetTicks(), SDL_AddTimer(), SDL_GetPerformanceCounter(),
SDL_GetPerformanceFrequency(), etc.)
* file I/O via SDL_RWops
* mouse input (unsupported on Windows Phone)
* audio, via SDL's WASAPI backend (if you want to record, your app must
have "Microphone" capabilities enabled in its manifest, and the user must
not have blocked access. Otherwise, capture devices will fail to work,
presenting as a device disconnect shortly after opening it.)
* .DLL file loading. Libraries *MUST* be packaged inside applications. Loading
anything outside of the app is not supported.
* system path retrieval via SDL's filesystem APIs
* game controllers. Support is provided via the SDL_Joystick and
SDL_GameController APIs, and is backed by Microsoft's XInput API. Please
note, however, that Windows limits game-controller support in UWP apps to,
"Xbox compatible controllers" (many controllers that work in Win32 apps,
do not work in UWP, due to restrictions in UWP itself.)
* multi-touch input
* app events. SDL_APP_WILLENTER* and SDL_APP_DIDENTER* events get sent out as
appropriate.
* window events
* using Direct3D 11.x APIs outside of SDL. Non-XAML / Direct3D-only apps can
choose to render content directly via Direct3D, using SDL to manage the
internal WinRT window, as well as input and audio. (Use
SDL_GetWindowWMInfo() to get the WinRT 'CoreWindow', and pass it into
IDXGIFactory2::CreateSwapChainForCoreWindow() as appropriate.)
* What partially works:
* keyboard input. Most of WinRT's documented virtual keys are supported, as
well as many keys with documented hardware scancodes. Converting
SDL_Scancodes to or from SDL_Keycodes may not work, due to missing APIs
(MapVirtualKey()) in Microsoft's Windows Store / UWP APIs.
* SDLmain. WinRT uses a different signature for each app's main() function.
SDL-based apps that use this port must compile in SDL_winrt_main_NonXAML.cpp
(in `SDL\src\main\winrt\`) directly in order for their C-style main()
functions to be called.
* What doesn't work:
* compilation with anything other than Visual C++
* programmatically-created custom cursors. These don't appear to be supported
by WinRT. Different OS-provided cursors can, however, be created via
SDL_CreateSystemCursor() (unsupported on Windows Phone)
* SDL_WarpMouseInWindow() or SDL_WarpMouseGlobal(). This are not currently
supported by WinRT itself.
* joysticks and game controllers that either are not supported by
Microsoft's XInput API, or are not supported within UWP apps (many
controllers that work in Win32, do not work in UWP, due to restrictions in
UWP itself).
* turning off VSync when rendering on Windows Phone. Attempts to turn VSync
off on Windows Phone result either in Direct3D not drawing anything, or it
forcing VSync back on. As such, SDL_RENDERER_PRESENTVSYNC will always get
turned-on on Windows Phone. This limitation is not present in non-Phone
WinRT (such as Windows 8.x), where turning off VSync appears to work.
* probably anything else that's not listed as supported
Upgrade Notes
-------------
#### SDL_GetPrefPath() usage when upgrading WinRT apps from SDL 2.0.3
SDL 2.0.4 fixes two bugs found in the WinRT version of SDL_GetPrefPath().
The fixes may affect older, SDL 2.0.3-based apps' save data. Please note
that these changes only apply to SDL-based WinRT apps, and not to apps for
any other platform.
1. SDL_GetPrefPath() would return an invalid path, one in which the path's
directory had not been created. Attempts to create files there
(via fopen(), for example), would fail, unless that directory was
explicitly created beforehand.
2. SDL_GetPrefPath(), for non-WinPhone-based apps, would return a path inside
a WinRT 'Roaming' folder, the contents of which get automatically
synchronized across multiple devices. This process can occur while an
application runs, and can cause existing save-data to be overwritten
at unexpected times, with data from other devices. (Windows Phone apps
written with SDL 2.0.3 did not utilize a Roaming folder, due to API
restrictions in Windows Phone 8.0).
SDL_GetPrefPath(), starting with SDL 2.0.4, addresses these by:
1. making sure that SDL_GetPrefPath() returns a directory in which data
can be written to immediately, without first needing to create directories.
2. basing SDL_GetPrefPath() off of a different, non-Roaming folder, the
contents of which do not automatically get synchronized across devices
(and which require less work to use safely, in terms of data integrity).
Apps that wish to get their Roaming folder's path can do so either by using
SDL_WinRTGetFSPathUTF8(), SDL_WinRTGetFSPathUNICODE() (which returns a
UCS-2/wide-char string), or directly through the WinRT class,
Windows.Storage.ApplicationData.
Setup, High-Level Steps
-----------------------
The steps for setting up a project for an SDL/WinRT app looks like the
following, at a high-level:
1. create a new Visual C++ project using Microsoft's template for a,
"Direct3D App".
2. remove most of the files from the project.
3. make your app's project directly reference SDL/WinRT's own Visual C++
project file, via use of Visual C++'s "References" dialog. This will setup
the linker, and will copy SDL's .dll files to your app's final output.
4. adjust your app's build settings, at minimum, telling it where to find SDL's
header files.
5. add files that contains a WinRT-appropriate main function, along with some
data to make sure mouse-cursor-hiding (via SDL_ShowCursor(SDL_DISABLE) calls)
work properly.
6. add SDL-specific app code.
7. build and run your app.
Setup, Detailed Steps
---------------------
### 1. Create a new project ###
Create a new project using one of Visual C++'s templates for a plain, non-XAML,
"Direct3D App" (XAML support for SDL/WinRT is not yet ready for use). If you
don't see one of these templates, in Visual C++'s 'New Project' dialog, try
using the textbox titled, 'Search Installed Templates' to look for one.
### 2. Remove unneeded files from the project ###
In the new project, delete any file that has one of the following extensions:
- .cpp
- .h
- .hlsl
When you are done, you should be left with a few files, each of which will be a
necessary part of your app's project. These files will consist of:
- an .appxmanifest file, which contains metadata on your WinRT app. This is
similar to an Info.plist file on iOS, or an AndroidManifest.xml on Android.
- a few .png files, one of which is a splash screen (displayed when your app
launches), others are app icons.
- a .pfx file, used for code signing purposes.
### 3. Add references to SDL's project files ###
SDL/WinRT can be built in multiple variations, spanning across three different
CPU architectures (x86, x64, and ARM) and two different configurations
(Debug and Release). WinRT and Visual C++ do not currently provide a means
for combining multiple variations of one library into a single file.
Furthermore, it does not provide an easy means for copying pre-built .dll files
into your app's final output (via Post-Build steps, for example). It does,
however, provide a system whereby an app can reference the MSVC projects of
libraries such that, when the app is built:
1. each library gets built for the appropriate CPU architecture(s) and WinRT
platform(s).
2. each library's output, such as .dll files, get copied to the app's build
output.
To set this up for SDL/WinRT, you'll need to run through the following steps:
1. open up the Solution Explorer inside Visual C++ (under the "View" menu, then
"Solution Explorer")
2. right click on your app's solution.
3. navigate to "Add", then to "Existing Project..."
4. find SDL/WinRT's Visual C++ project file and open it, in the `VisualC-WinRT`
directory.
5. once the project has been added, right-click on your app's project and
select, "References..."
6. click on the button titled, "Add New Reference..."
7. check the box next to SDL
8. click OK to close the dialog
9. SDL will now show up in the list of references. Click OK to close that
dialog.
Your project is now linked to SDL's project, insofar that when the app is
built, SDL will be built as well, with its build output getting included with
your app.
### 4. Adjust Your App's Build Settings ###
Some build settings need to be changed in your app's project. This guide will
outline the following:
- making sure that the compiler knows where to find SDL's header files
- **Optional for C++, but NECESSARY for compiling C code:** telling the
compiler not to use Microsoft's C++ extensions for WinRT development.
- **Optional:** telling the compiler not generate errors due to missing
precompiled header files.
To change these settings:
1. right-click on the project
2. choose "Properties"
3. in the drop-down box next to "Configuration", choose, "All Configurations"
4. in the drop-down box next to "Platform", choose, "All Platforms"
5. in the left-hand list, expand the "C/C++" section
6. select "General"
7. edit the "Additional Include Directories" setting, and add a path to SDL's
"include" directory
8. **Optional: to enable compilation of C code:** change the setting for
"Consume Windows Runtime Extension" from "Yes (/ZW)" to "No". If you're
working with a completely C++ based project, this step can usually be
omitted.
9. **Optional: to disable precompiled headers (which can produce
'stdafx.h'-related build errors, if setup incorrectly:** in the left-hand
list, select "Precompiled Headers", then change the setting for "Precompiled
Header" from "Use (/Yu)" to "Not Using Precompiled Headers".
10. close the dialog, saving settings, by clicking the "OK" button
### 5. Add a WinRT-appropriate main function, and a blank-cursor image, to the app. ###
A few files should be included directly in your app's MSVC project, specifically:
1. a WinRT-appropriate main function (which is different than main() functions on
other platforms)
2. a Win32-style cursor resource, used by SDL_ShowCursor() to hide the mouse cursor
(if and when the app needs to do so). *If this cursor resource is not
included, mouse-position reporting may fail if and when the cursor is
hidden, due to possible bugs/design-oddities in Windows itself.*
To include these files for C/C++ projects:
1. right-click on your project (again, in Visual C++'s Solution Explorer),
navigate to "Add", then choose "Existing Item...".
2. navigate to the directory containing SDL's source code, then into its
subdirectory, 'src/main/winrt/'. Select, then add, the following files:
- `SDL_winrt_main_NonXAML.cpp`
- `SDL3-WinRTResources.rc`
- `SDL3-WinRTResource_BlankCursor.cur`
3. right-click on the file `SDL_winrt_main_NonXAML.cpp` (as listed in your
project), then click on "Properties...".
4. in the drop-down box next to "Configuration", choose, "All Configurations"
5. in the drop-down box next to "Platform", choose, "All Platforms"
6. in the left-hand list, click on "C/C++"
7. change the setting for "Consume Windows Runtime Extension" to "Yes (/ZW)".
8. click the OK button. This will close the dialog.
**NOTE: C++/CX compilation is currently required in at least one file of your
app's project. This is to make sure that Visual C++'s linker builds a 'Windows
Metadata' file (.winmd) for your app. Not doing so can lead to build errors.**
For non-C++ projects, you will need to call SDL_WinRTRunApp from your language's
main function, and generate SDL3-WinRTResources.res manually by using `rc` via
the Developer Command Prompt and including it as a <Win32Resource> within the
first <PropertyGroup> block in your Visual Studio project file.
### 6. Add app code and assets ###
At this point, you can add in SDL-specific source code. Be sure to include a
C-style main function (ie: `int main(int argc, char *argv[])`). From there you
should be able to create a single `SDL_Window` (WinRT apps can only have one
window, at present), as well as an `SDL_Renderer`. Direct3D will be used to
draw content. Events are received via SDL's usual event functions
(`SDL_PollEvent`, etc.) If you have a set of existing source files and assets,
you can start adding them to the project now. If not, or if you would like to
make sure that you're setup correctly, some short and simple sample code is
provided below.
#### 6.A. ... when creating a new app ####
If you are creating a new app (rather than porting an existing SDL-based app),
or if you would just like a simple app to test SDL/WinRT with before trying to
get existing code working, some working SDL/WinRT code is provided below. To
set this up:
1. right click on your app's project
2. select Add, then New Item. An "Add New Item" dialog will show up.
3. from the left-hand list, choose "Visual C++"
4. from the middle/main list, choose "C++ File (.cpp)"
5. near the bottom of the dialog, next to "Name:", type in a name for your
source file, such as, "main.cpp".
6. click on the Add button. This will close the dialog, add the new file to
your project, and open the file in Visual C++'s text editor.
7. Copy and paste the following code into the new file, then save it.
```c
#include <SDL.h>
int main(int argc, char **argv)
{
SDL_DisplayMode mode;
SDL_Window * window = NULL;
SDL_Renderer * renderer = NULL;
SDL_Event evt;
SDL_bool keep_going = SDL_TRUE;
if (SDL_Init(SDL_INIT_VIDEO) != 0) {
return 1;
} else if (SDL_GetCurrentDisplayMode(0, &mode) != 0) {
return 1;
} else if (SDL_CreateWindowAndRenderer(mode.w, mode.h, SDL_WINDOW_FULLSCREEN, &window, &renderer) != 0) {
return 1;
}
while (keep_going) {
while (SDL_PollEvent(&evt)) {
if ((evt.type == SDL_KEYDOWN) && (evt.key.keysym.sym == SDLK_ESCAPE)) {
keep_going = SDL_FALSE;
}
}
SDL_SetRenderDrawColor(renderer, 0, 255, 0, 255);
SDL_RenderClear(renderer);
SDL_RenderPresent(renderer);
}
SDL_Quit();
return 0;
}
```
#### 6.B. Adding code and assets ####
If you have existing code and assets that you'd like to add, you should be able
to add them now. The process for adding a set of files is as such.
1. right click on the app's project
2. select Add, then click on "New Item..."
3. open any source, header, or asset files as appropriate. Support for C and
C++ is available.
Do note that WinRT only supports a subset of the APIs that are available to
Win32-based apps. Many portions of the Win32 API and the C runtime are not
available.
A list of unsupported C APIs can be found at
<http://msdn.microsoft.com/en-us/library/windows/apps/jj606124.aspx>
General information on using the C runtime in WinRT can be found at
<https://msdn.microsoft.com/en-us/library/hh972425.aspx>
A list of supported Win32 APIs for WinRT apps can be found at
<http://msdn.microsoft.com/en-us/library/windows/apps/br205757.aspx>. To note,
the list of supported Win32 APIs for Windows Phone 8.0 is different.
That list can be found at
<http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662956(v=vs.105).aspx>
### 7. Build and run your app ###
Your app project should now be setup, and you should be ready to build your app.
To run it on the local machine, open the Debug menu and choose "Start
Debugging". This will build your app, then run your app full-screen. To switch
out of your app, press the Windows key. Alternatively, you can choose to run
your app in a window. To do this, before building and running your app, find
the drop-down menu in Visual C++'s toolbar that says, "Local Machine". Expand
this by clicking on the arrow on the right side of the list, then click on
Simulator. Once you do that, any time you build and run the app, the app will
launch in window, rather than full-screen.
#### 7.A. Running apps on older, ARM-based, "Windows RT" devices ####
**These instructions do not include Windows Phone, despite Windows Phone
typically running on ARM processors.** They are specifically for devices
that use the "Windows RT" operating system, which was a modified version of
Windows 8.x that ran primarily on ARM-based tablet computers.
To build and run the app on ARM-based, "Windows RT" devices, you'll need to:
- install Microsoft's "Remote Debugger" on the device. Visual C++ installs and
debugs ARM-based apps via IP networks.
- change a few options on the development machine, both to make sure it builds
for ARM (rather than x86 or x64), and to make sure it knows how to find the
Windows RT device (on the network).
Microsoft's Remote Debugger can be found at
<https://msdn.microsoft.com/en-us/library/hh441469.aspx>. Please note
that separate versions of this debugger exist for different versions of Visual
C++, one each for MSVC 2015, 2013, and 2012.
To setup Visual C++ to launch your app on an ARM device:
1. make sure the Remote Debugger is running on your ARM device, and that it's on
the same IP network as your development machine.
2. from Visual C++'s toolbar, find a drop-down menu that says, "Win32". Click
it, then change the value to "ARM".
3. make sure Visual C++ knows the hostname or IP address of the ARM device. To
do this:
1. open the app project's properties
2. select "Debugging"
3. next to "Machine Name", enter the hostname or IP address of the ARM
device
4. if, and only if, you've turned off authentication in the Remote Debugger,
then change the setting for "Require Authentication" to No
5. click "OK"
4. build and run the app (from Visual C++). The first time you do this, a
prompt will show up on the ARM device, asking for a Microsoft Account. You
do, unfortunately, need to log in here, and will need to follow the
subsequent registration steps in order to launch the app. After you do so,
if the app didn't already launch, try relaunching it again from within Visual
C++.
Troubleshooting
---------------
#### Build fails with message, "error LNK2038: mismatch detected for 'vccorlib_lib_should_be_specified_before_msvcrt_lib_to_linker'"
Try adding the following to your linker flags. In MSVC, this can be done by
right-clicking on the app project, navigating to Configuration Properties ->
Linker -> Command Line, then adding them to the Additional Options
section.
* For Release builds / MSVC-Configurations, add:
/nodefaultlib:vccorlib /nodefaultlib:msvcrt vccorlib.lib msvcrt.lib
* For Debug builds / MSVC-Configurations, add:
/nodefaultlib:vccorlibd /nodefaultlib:msvcrtd vccorlibd.lib msvcrtd.lib
#### Mouse-motion events fail to get sent, or SDL_GetMouseState() fails to return updated values
This may be caused by a bug in Windows itself, whereby hiding the mouse
cursor can cause mouse-position reporting to fail.
SDL provides a workaround for this, but it requires that an app links to a
set of Win32-style cursor image-resource files. A copy of suitable resource
files can be found in `src/main/winrt/`. Adding them to an app's Visual C++
project file should be sufficient to get the app to use them.
#### SDL's Visual Studio project file fails to open, with message, "The system can't find the file specified."
This can be caused for any one of a few reasons, which Visual Studio can
report, but won't always do so in an up-front manner.
To help determine why this error comes up:
1. open a copy of Visual Studio without opening a project file. This can be
accomplished via Windows' Start Menu, among other means.
2. show Visual Studio's Output window. This can be done by going to VS'
menu bar, then to View, and then to Output.
3. try opening the SDL project file directly by going to VS' menu bar, then
to File, then to Open, then to Project/Solution. When a File-Open dialog
appears, open the SDL project (such as the one in SDL's source code, in its
directory, VisualC-WinRT/UWP_VS2015/).
4. after attempting to open SDL's Visual Studio project file, additional error
information will be output to the Output window.
If Visual Studio reports (via its Output window) that the project:
"could not be loaded because it's missing install components. To fix this launch Visual Studio setup with the following selections:
Microsoft.VisualStudio.ComponentGroup.UWP.VC"
... then you will need to re-launch Visual Studio's installer, and make sure that
the workflow for "Universal Windows Platform development" is checked, and that its
optional component, "C++ Universal Windows Platform tools" is also checked. While
you are there, if you are planning on targeting UWP / Windows 10, also make sure
that you check the optional component, "Windows 10 SDK (10.0.10240.0)". After
making sure these items are checked as-appropriate, install them.
Once you install these components, try re-launching Visual Studio, and re-opening
the SDL project file. If you still get the error dialog, try using the Output
window, again, seeing what Visual Studio says about it.
#### Game controllers / joysticks aren't working!
Windows only permits certain game controllers and joysticks to work within
WinRT / UWP apps. Even if a game controller or joystick works in a Win32
app, that device is not guaranteed to work inside a WinRT / UWP app.
According to Microsoft, "Xbox compatible controllers" should work inside
UWP apps, potentially with more working in the future. This includes, but
may not be limited to, Microsoft-made Xbox controllers and USB adapters.

#define SDL_HINT_WINDOW_NO_ACTIVATION_WHEN_SHOWN "SDL_WINDOW_NO_ACTIVATION_WHEN_SHOWN"
/** \brief Allows back-button-press events on Windows Phone to be marked as handled
*
* Windows Phone devices typically feature a Back button. When pressed,
* the OS will emit back-button-press events, which apps are expected to
* handle in an appropriate manner. If apps do not explicitly mark these
* events as 'Handled', then the OS will invoke its default behavior for
* unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
* terminate the app (and attempt to switch to the previous app, or to the
* device's home screen).
*
* Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
* to mark back-button-press events as Handled, if and when one is sent to
* the app.
*
* Internally, Windows Phone sends back button events as parameters to
* special back-button-press callback functions. Apps that need to respond
* to back-button-press events are expected to register one or more
* callback functions for such, shortly after being launched (during the
* app's initialization phase). After the back button is pressed, the OS
* will invoke these callbacks. If the app's callback(s) do not explicitly
* mark the event as handled by the time they return, or if the app never
* registers one of these callback, the OS will consider the event
* un-handled, and it will apply its default back button behavior (terminate
* the app).
*
* SDL registers its own back-button-press callback with the Windows Phone
* OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
* and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
* it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
* If the hint's value is set to "1", the back button event's Handled
* property will get set to 'true'. If the hint's value is set to something
* else, or if it is unset, SDL will leave the event's Handled property
* alone. (By default, the OS sets this property to 'false', to note.)
*
* SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
* back button is pressed, or can set it in direct-response to a back button
* being pressed.
*
* In order to get notified when a back button is pressed, SDL apps should
* register a callback function with SDL_AddEventWatch(), and have it listen
* for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
* (Alternatively, SDL_KEYUP events can be listened-for. Listening for
* either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
* set by such a callback, will be applied to the OS' current
* back-button-press event.
*
* More details on back button behavior in Windows Phone apps can be found
* at the following page, on Microsoft's developer site:
* http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx

* Please note that a privacy policy's contents are not set via this hint. A separate
* hint, SDL_HINT_WINRT_PRIVACY_POLICY_URL, is used to link to the actual text of the

*
* The default value is "Privacy Policy". This hint should only be set during app

* SDL provides code to add a URL-based link there, which can point to the app's

*
* To setup a URL to an app's privacy policy, set SDL_HINT_WINRT_PRIVACY_POLICY_URL

*
* The default value is "", which will prevent SDL from adding a privacy policy
* link to the Settings charm. This hint should only be set during app init.

/* At least one file in any SDL/WinRT app appears to require compilation
with C++/CX, otherwise a Windows Metadata file won't get created, and
an APPX0702 build error can appear shortly after linking.
The following set of preprocessor code forces this file to be compiled
as C++/CX, which appears to cause Visual C++ 2012's build tools to
create this .winmd file, and will help allow builds of SDL/WinRT apps
to proceed without error.
If other files in an app's project enable C++/CX compilation, then it might
be possible for SDL_winrt_main_NonXAML.cpp to be compiled without /ZW,
for Visual C++'s build tools to create a winmd file, and for the app to
build without APPX0702 errors. In this case, if
SDL_WINRT_METADATA_FILE_AVAILABLE is defined as a C/C++ macro, then
the #error (to force C++/CX compilation) will be disabled.
Please note that /ZW can be specified on a file-by-file basis. To do this,
right click on the file in Visual C++, click Properties, then change the
setting through the dialog that comes up.

// HACK ALERT: TL;DR - Hiding the cursor in WinRT/UWP apps is weird, and
// 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/SDL3-WinRTResource_BlankCursor.cur -- cursor pixel data
// - src/main/winrt/SDL3-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);

// DLudwig, 2012-12-28: On some systems, namely Visual Studio's Windows
// Simulator, as well as Windows 8 in a Parallels 8 VM, MouseEventArgs'
// MouseDelta field often reports very large values. More information
// on this can be found at the following pages on MSDN:
// - http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/a3c789fa-f1c5-49c4-9c0a-7db88d0f90f8
// - https://connect.microsoft.com/VisualStudio/Feedback/details/756515
//
// The values do not appear to be as large when running on some systems,
// most notably a Surface RT. Furthermore, the values returned by
// CoreWindow's PointerMoved event, and sent to this class' OnPointerMoved
// method, do not ever appear to be large, even when MouseEventArgs'
// MouseDelta is reporting to the contrary.
//
// On systems with the large-values behavior, it appears that the values
// get reported as if the screen's size is 65536 units in both the X and Y
// dimensions. This can be viewed by using Windows' now-private, "Raw Input"
// APIs. (GetRawInputData, RegisterRawInputDevices, WM_INPUT, etc.)
//
// MSDN's documentation on MouseEventArgs' MouseDelta field (at
// http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.input.mouseeventargs.mousedelta ),
// does not seem to indicate (to me) that its values should be so large. It
// says that its values should be a "change in screen location". I could
// be misinterpreting this, however a post on MSDN from a Microsoft engineer (see:
// http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/09a9868e-95bb-4858-ba1a-cb4d2c298d62 ),
// indicates that these values are in DIPs, which is the same unit used
// by CoreWindow's PointerMoved events (via the Position field in its CurrentPoint
// property. See http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.input.pointerpoint.position.aspx
// for details.)
//
// To note, PointerMoved events are sent a 'RawPosition' value (via the
// CurrentPoint property in MouseEventArgs), however these do not seem
// to exhibit the same large-value behavior.
//
// The values passed via PointerMoved events can't always be used for relative
// mouse motion, unfortunately. Its values are bound to the cursor's position,
// which stops when it hits one of the screen's edges. This can be a problem in
// first person shooters, whereby it is normal for mouse motion to travel far
// along any one axis for a period of time. MouseMoved events do not have the
// screen-bounding limitation, and can be used regardless of where the system's
// cursor is.
//
// One possible workaround would be to programmatically set the cursor's
// position to the screen's center (when SDL's relative mouse mode is enabled),
// however WinRT does not yet seem to have the ability to set the cursor's
// position via a public API. Win32 did this via an API call, SetCursorPos,
// however WinRT makes this function be private. Apps that use it won't get
// approved for distribution in the Windows Store. I've yet to be able to find
// a suitable, store-friendly counterpart for WinRT.
//
// There may be some room for a workaround whereby OnPointerMoved's values
// are compared to the values from OnMouseMoved in order to detect
// when this bug is active. A suitable transformation could then be made to
// OnMouseMoved's values. For now, however, the system-reported values are sent
// to SDL with minimal transformation: from native screen coordinates (in DIPs)
// to SDL window coordinates.
