|

// 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.

// - 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)
|
