iOS 8 introduces LaunchScreen NIBs which use autolayout to handle all devices and orientations with a single NIB instead of multiple launch images. This is also the only way to get the App Store badge "Optimized for iPhone 6 and iPhone 6 Plus". So if the application is running on iOS 8 or greater AND has specified a LaunchScreen in their Info.plist, this patch will use the NIB as the launch screen. Otherwise, the code falls back to the legacy code path.
Note: Upon audit of the legacy path, it appears that it does not properly handle the UILaunchImages Info.plist convention. I've added comments inline to the code about this. However, in about a year from now, nobody is going to care about this path since everybody should be using LaunchScreen NIBs.
SDL_HINT_WINRT_PREF_PATH_ROOT allows WinRT apps to alter the path that
SDL_GetPrefPath() returns. Setting it to "local" uses the app's
OS-defined Local folder, setting it to "roaming" uses the app's OS-defined
Roaming folder.
Roaming folder support is not available in Windows Phone 8.0. Attempts to
make SDL_GetPrefPath() return a Roaming folder on this OS will be ignored.
Various bits of documentation on this were added to SDL_hints.h, and to
README-winrt.md
Further support regarding IME and on-screen keyboards is pending, some of
which might not be 100% compatible with other platforms, given WinRT platform
restrictions. An MSDN article at http://msdn.microsoft.com/en-us/library/windows/apps/hh465404.aspx
indicates that on-screen keyboard display requires that the user first tap on
a Windows/XAML text control.
This change adds basic SDL_TEXTINPUT support, with input coming from hardware
keyboards, at a minimum, and without the need for XAML integration (which is
still pending integration into SDL, by and large).
This scenario can occur, for example, when the 4-finger touch sequence is used to switch spaces. the SDL window does not receive the touch up events and ends up thinking there are far more fingers on the pad than there are.
So the solution here is everytime a new "touch" appears we can through and check if there are any existing known touches by the OS and if there are none, abut SDL things there are, we simply go through and cancel the SDL touches.
Side affects.
- the "touch up" won't occur until the users sends a new touch (could be well after the actual release really did occur)
Windows Phone 8.0 either did not define, or provide access to, a 'RoamingFolder'
or 'TemporaryFolder' for apps to use. Windows 8.0 and 8.1 do, as does
Windows Phone 8.1. This change allows SDL-based Windows Phone 8.1 apps to
access these folders, via either the SDL_WinRTGetFSPathUNICODE() or
SDL_WinRTGetFSPathUTF8() functions.
SDL_GetPrefPath(), which on WinRT, is based on SDL_WinRTGetFSPathUTF8(), will
continue to return the app's 'local' folder, despite Windows 8.x
counterpart apps using the 'roaming' folder, in order to preserve compatibility
when 8.0-based Phone apps upgrade to 8.1-based Phone apps.
This patch makes sure that any SDL_MOUSEBUTTONDOWN, SDL_MOUSEBUTTONUP, and
SDL_MOUSEMOTION events, as triggered by a touch event in a WinRT app, set the
event's 'which' field to SDL_TOUCH_MOUSEID. Previously, this was getting set
to the same value as events from a real mouse, '0'.
Thanks to Diego for providing information on this bug, and to Tamas Hamor for
sending over a patch!
SDL2 reports the following message when we type the "/" on br-abnt2 keyboards:
The key you just pressed is not recognized by SDL. \
To help get this fixed, please report this to the SDL mailing list \
<sdl@libsdl.org> X11 KeyCode 97 (89), X11 KeySym 0x2F (slash).
That's because the corresponding entry in the scancodes table is
marked with value SDL_SCANCODE_UNKNOWN.
This commit fixes that adding the value SDL_SCANCODE_SLASH for this entry.
- Removed USE_GETTICKCOUNT code; it's never used now.
- Reduced the number of preprocessor checks for WinRT.
- Renamed timeSetPeriod() so it doesn't look like a Win32 API call.
An existing hint lets apps that don't need the timer resolution changed avoid
this, to save battery, etc, but this fixes several problems in timing, audio
callbacks not firing fast enough, etc.
Fixes Bugzilla #2944.
