Camilla Löwy	d11cb3779b	Win32: Remove support for Windows XP and Vista It's increasingly difficult to maintain a safe testing environment for Windows XP, and so increasingly a burden on contributors to maintain support for it. Windows XP has been out of of support since 2014 and should not be used as a desktop OS. Fixes #2505	2025-07-11 16:49:23 +02:00
Camilla Löwy	d1b87143bc	Win32: Remove support for original MinGW The original MinGW distribution appears to no longer be maintained and should not be used. Anyone still using MinGW should consider switching to the MinGW-w64 fork or another actively maintained toolchain. MinGW-w64 supports 64-bit binaries and provides much newer compilers and Win32 headers. Fixes #2540	2025-07-10 17:59:12 +02:00
Grzesiek11	7235dddefd	Fix extended scancode of 0 not being processed correctly On Windows, keyboard events with an extended 0 Windows scancode are now processed by mapping the virtual-key code to a Windows scancode using the Win32 MapVirtualKey function. Some keyboard scancodes (in particular, ones used for some non-typical keys) are not mapped to corresponding Windows scancodes, and are instead mapped to an extended 0 Windows scancode, with the distinction being only in the virtual-key code. This causes GLFW to report a 256 GLFW scancode (0x00 \| 0x100, 0x100 being the extended bit bitmask) for any of those keys, which causes API consumers to be unable to distinguish between them. There exists, however, a Win32 function MapVirtualKey that maps those virtual key-codes to proper Windows scancodes. GLFW even appears to use this workaround, but after further inspection, it checks whether the Windows scancode is 0 (0x00), and not extended 0 (0x100). This change makes GLFW check for the extended 0 keycode instead, which seems to work correctly. I'm not sure if checking for the non-extended 0 Windows scancode was intentional, as I never seem to have encountered one during testing with multiple keyboards. Thus, the handling of the non-extended 0 Windows scancode was removed, but it can be brought back if necessary.	2025-04-04 02:55:49 +02:00
