The intent of enforcing GLFW_EGL_CONTEXT_API for EGL native access
functions was to ensure that the application had requested the same
context creation API at window creation time that it then attempted
native access for.
With the 3.4 ABI this both isn't true anymore, as a single binary may
have multiple meanings of GLFW_NATIVE_CONTEXT_API, and is no longer
necessary, since glfwGetPlatform provides enough information to
disambiguate even without knowing what GLFW_PLATFORM was set to.
This all leaves the requirement that the context creation API be
GLFW_EGL_CONTEXT_API as just an unnecessary annoyance.
Fixes#2518
This provides very limited support for context creation via EGL on the
Null platform. It supports Unix-like systems with a version of Mesa
that provides EGL_MESA_platform_surfaceless.
Even then, the actual framebuffer provided is not resized along with the
'window'. That will hopefully change once context and framebuffer
creation are separated, but this commit should at least allow more
applications than before to run on the Null platform.
This adds support for Vulkan 'window' surface creation on the Null
platform via the VK_EXT_headless_surface extension, where available.
Tested with MoltenVK.
This adds the GLFW_UNLIMITED_MOUSE_BUTTONS input mode which permits
mouse buttons over GLFW_MOUSE_BUTTON_LAST to be reported to the mouse
button callback.
Closes#2423
When GLFW_ANY_PLATFORM is used (which is the default), X11 would be
selected on a Wayland system with XWayland and where XDG_SESSION_TYPE
was not set.
Closes#2035
This adds a function for querying the current title of a window. This
currently returns a copy of the last title set via GLFW.
Fixes#1448Closes#1909Closes#2482
The actual reported bug was fixed at some point during the refactoring
of the Wayland backend. This is only a bit of tidying. Updating the
cache before emitting events is always a nice thing to do.
Closes#2046
This adds the GLFW_SCALE_FRAMEBUFFER window hint, enabling control of
framebuffer scaling across Wayland and macOS. On macOS, this window
hint is a new name for GLFW_COCOA_RETINA_FRAMEBUFFER, and both hint
names will modify the same hint.
This is now a more symmetric counterpart to GLFW_SCALE_TO_MONITOR and,
weirdly, they each apply neatly to half of the supported platforms.
This commit is mostly documentation updates to better integrate and
contrast these two scaling mechanisms.
The calculation of framebuffer size is about to get more complicated
with the introduction of fractional-scale-v1, so only do it in one
place.
This is also a tiny preparation for eventually behaving better towards
wl_egl_window_resize.
We are about to introduce another scaling method (fractional-scale-v1),
so it will become more important to be specific about what scales are
used where and what their units are.
This removes 'content scale' from window and monitor structs. A monitor
(output) now has just a 'scale', which becomes a 'buffer scale' when
applied to a window. A window now has a list of 'output scales' to
select its buffer scale from. Content scales are calculated from the
respective monitor or window when queried, even if the calculation right
now is to just return the same value as before.
