Camilla Löwy	949275bbed	Cocoa: Fix call to NSWindow from non-main threads glfwSwapBuffers may be called by any thread but NSWindow may not. Bug introduced by `c3ca88055f` and reported by @crujose.	2020-04-30 22:44:54 +02:00
Camilla Löwy	cab41529da	X11: Improve non-XKB fallback for key mapping A regression introduced by `b889aa7841` broke the special handling of numpad keys for the non-XKB fallback path. The non-functional remains were later removed. This restores the original behavior.	2020-04-23 22:13:18 +02:00
Camilla Löwy	318e08d914	X11: Add additional XKB key names for Right Alt	2020-04-23 17:42:36 +02:00

Camilla Löwy	ee45b58647	X11: Fix X keycode ranges for XKB and core This replaces the hardcoded keycode ranges and various kludgy range checks with the actual ranges reported by Xlib and XKB.	2020-03-31 17:31:01 +02:00
Camilla Löwy	215a05af3d	Update changelog and add credit Related to #1598.	2020-03-31 17:30:51 +02:00
Ali Sherief	a41a58a95e	X11: Fix function keys mapped to GLFW_KEY_UNKNOWN This fixes the issue where function keys would be reported as GLFW_KEY_UNKNOWN if XKB was available and one of the configured keyboard layouts was Arabic. This is only part of #1598, because the full patch removed parts of the fallback path for when XKB is unavailable. Closes #1598.	2020-03-31 17:03:29 +02:00
Camilla Löwy	e65de2941c	X11: Improve window handle race condition The non-root parent window owned by the WM could be destroyed before we process the ConfigureNotify event using the cached parent handle. Bug was found by unmapping a decorated window. This like all uses of the Xlib error handler is not thread safe and there is nothing we can do about that short of moving to XCB. Fixes #1633.	2020-03-31 17:03:29 +02:00
Camilla Löwy	2c8e0512dd	X11: Filter out Xlib errors from other connections	2020-03-16 17:15:07 +01:00
Camilla Löwy	44b5d06583	X11: Add support for XIM callbacks This adds support for the XIM instantiate and destroy callbacks, letting GLFW detect both when the current input method disappears and when a new one is started. Tested with ibus.	2020-03-12 21:05:54 +01:00
Camilla Löwy	350ba73267	Update linmath.h This updates our linmath.h to the latest version plus minor local fixes for MSVC and Clang. Fixes #1653.	2020-03-12 02:17:17 +01:00
Camilla Löwy	9516df52a4	Fix unclear language in build guide Fixes #1658.	2020-03-12 01:57:58 +01:00
Camilla Löwy	72366ac9a9	Cocoa: Finish launching NSApp in glfwInit This moves the remaining bits of NSApplication initialization into _glfwPlatformInit. As a side-effect of this, any command-line program initializing GLFW will get a menu bar, which is not ideal. If this has happened to you and a bisect led you here, please see the GLFW_COCOA_MENUBAR init hint introduced in GLFW 3.3. If this patch is a terrible idea, please get in touch in the 3.4 release timeframe. This is a replacement for `6e6805000a`, which attempts to preserve the existing menu bar creation behavior for the 3.3-stable branch. Fixes #1649.	2020-03-12 01:56:35 +01:00
Camilla Löwy	6aca3e99f0	Wayland: Remove unused link-time dependency The wayland-egl library is now loaded dynamically at init. This narrows the pkgconfig dependencies to the link-time depdendencies.	2020-02-12 19:02:46 +01:00

This fills in the missing scancode by translating the provided virtual key. Rather than further complicate a single-use function, its body is merged into the key message handler. Fixes #1623.	2020-01-16 23:52:36 +01:00

Camilla Löwy	a491b0698c	Win32: Use non-async key state for modifier hack The synchronous key state seems to make more sense in context.	2020-01-16 23:16:43 +01:00
Camilla Löwy	562c17d131	Win32: Fix no Super key release event after Win+V The Win+V hotkey brings up a clipboard history IME that consumes the key release. This adds left and right Super to the modifier keys manually polled for undetected release during event processing. Fixes #1622.	2020-01-16 23:16:41 +01:00
Camilla Löwy	7da87aaae7	Cocoa: Add fully dynamic loading of Vulkan loader If the application is not linked against the Vulkan loader and relies on a third-party loader library or glfwGetInstanceProcAddress, then our call to dlopen will fail without a custom dyld environment variable. This adds a fallback of looking in the directory of the main executable, which matches the bundle structure recommended by the Vulkan SDK, making that finally work out of the box for fully dynamic loading.	2020-01-16 22:15:30 +01:00
Camilla Löwy	15d91801b7	Cocoa: Select Vulkan surface extension at runtime This mostly just follows the pattern established by X11. Related to #1619.	2020-01-16 21:53:18 +01:00
ByunghoonKim	c5cb4a253a	Cocoa: Add support for VK_EXT_metal_surface This adds optional support for the VK_EXT_metal_surface instance extension. Closes #1619.	2020-01-16 05:28:24 +01:00
Camilla Löwy	9372ba95fa	X11: Fix parent window handle initialization This should have been initialized to the screen root, not None. This issue was introduced by `fe57e3c292`. Fixes #1620.	2020-01-14 21:26:21 +01:00
Camilla Löwy	aa5e313561	X11: Fix BadMatch focusing a window on non-EWMH WM When the WM does not support EWMH or there is no WM running, GLFW falls back to XSetInputFocus, which will emit BadMatch if the window is not viewable, which will terminate the program. Bug spotted on IRC.	2020-01-06 22:45:56 +01:00
Camilla Löwy	fe57e3c292	X11: Fix no window position events during resize A window resize action that also resulting in the window being moved did not emit any window positions events, as the position of real ConfigureNotify events was ignored. The real events use parent coordinates instead of root coordinates so this adds parent tracking and conditional translation. Fixes #1613.	2020-01-01 16:56:32 +01:00

Luflosi	74a46dfa0c	Use the correct type in a for loop The `sizeof()` operator has the type `size_t`, so the `for` loop iterating over it should use the same type. Closes #1614.	2019-12-26 16:31:37 +01:00
Camilla Löwy	4ec7daf3e9	Cocoa: Replace display link with IOKit query This removes the final dependency on CoreVideo, using a display link to get the refresh rate of monitors where Core Graphics report a refresh rate of zero. Instead we now query the I/O registry directly, similarly to what the display link does at creation. Thanks to @OneSadCookie for pointers to this solution.	2019-12-25 21:53:04 +01:00

Camilla Löwy	b4a8eb9b19	Cocoa: Only create per-monitor display link once The display link query is not specific to any particular display mode and so only needs to be done once. The next step is to replace the display link altogether by querying IOKit directly, which is what the display link does.	2019-12-20 09:46:48 +01:00

Camilla Löwy	6e6805000a	Cocoa: Fix pre-window-creation event processing Polling the event queue before NSApp had been allowed to finish launching, in our case by starting our self-terminating run loop, triggered an assertion inside NSApplication. This fix, which makes all event processing functions capable of starting it, makes that assertion less likely. A more Cocoa-friendly fix would be to finish launching NSApp during glfwInit and let people annoyed by the menu bar disabled it with GLFW_COCOA_MENUBAR. That may not be suitable for 3.3-stable, though. Fixes #1543.	2019-12-09 22:25:59 +01:00
