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.
When using the fallback decorations, GLFW_HOVERED was true also when the
cursor was over one of the window decorations.
This also disentangles the GLFW_HOVERED state from the fallback
decorations. Because GLFW_HOVERED should have had the same behavior as
GLFW_MAIN_WINDOW, the latter has been removed.
We now have three window decoration paths in the Wayland backend:
libdecor decorations, XDG decorations and fallback decorations.
This makes it clearer when code relates to the fallback decoration path,
which should increasingly (hopefully) not get used.
This implements window focus requests via the xdg-activation-v1
protocol. These requests will likely only work when another window of
the same application already has input focus, but that isn't unlike the
behavior of other platforms.
The GLFW_FEATURE_UNAVAILABLE error has been removed from this function
for now.

This implements window attention requests via the xdg-activation-v1
protocol.
This was updated by @ elmindreda to work with recent Wayland related
changes to the main branch:
- Switched to current way of handling Wayland protocol files
- Added the xdg-activation-v1.xml protocol file to deps/wayland
- Added missing macros to rename protocol interface globals
The protocol file was copied from wayland-protocols 1.33.
Closes#2287
The list of compile-time dependencies on FreeBSD lacked evdev-proto.
Unlike on Linux, the input-event-codes.h header file was not implicitly
included on FreeBSD.
Fixes#2445
glfwGetKeyName emitted GLFW_INVALID_VALUE when passed GLFW_KEY_UNKNOWN
and any scancode not associated with a key token on that platform.
This causes physical keys with no associated key token to emit
GLFW_INVALID_VALUE when the key and scancode are passed directly from
the key event to glfwGetKeyName. This breaks the promise made in the
reference documentation for glfwGetKeyName.
This commit removes that error for the whole range of valid scancodes.
Fixes#1785
This brings the latest released versions of all used Wayland protocol
files into this repository, removing the need for the user to arrange
a sufficiently new version of wayland-protocols.
The wayland.xml protocol file was copied from wayland 1.22.0.
The additional protocol files were copied from wayland-protocols 1.32.
Because of how files are moved and renamed inside the wayland-protocols
repository, it will not always be possible to update all our protocol
files from a single release without also potentially updating related
code (acceptable) and prematurely breaking compatibility with
compositors that still only support an earlier incompatible version
(unacceptable).
The macro in src/CMakeLists.txt has been modified to hopefully make it
easier to add new protocol files. This made it necessary to change the
name of a few of the generated header files.
Closes#2053
The Wayland implementation of glfwWaitEvents* keeps waiting until it
sees evidence that a significant event has been processed. However,
this included updating an animated cursor (not a significant event)
but did not include previously buffered Wayland events or libdecor
events (definitely significant events).
This commit corrects these cases.
When setting the visibility of a libdecor frame on a compositor that
supports XDG decorations, libdecor 0.1 will update the geometry of the
XDG surface. GLFW attempted to set the visibility before having told
libdecor what size the content area is. This caused a Wayland protocol
error when libdecor attempted to set the window size to 0x0.
This commit adds setting the content area size for the libdecor frame
directly after creation, allowing libdecor to know what it's doing.
Much of libdecor is initialized only after certain events have been
received from the compositor and some parts of libdecor 0.1 are unsafe
to use until this delayed initialization has completed.
Since libdecor does not provide an API to query if or be notified when
this has happened, GLFW processed events until its newly created
libdecor frame had created its XDG shell objects.
This commit switches to using a generic Wayland sync point created just
after libdecor (and presumably its plugin) has set up its delayed
initialization, instead of relying on the more specific implementation
detail mentioned above.
It also makes this wait mandatory before the first libdecor frame is
created instead of a pre-condition for certain libdecor frame calls,
hopefully removing even more dependence on implementation details.
A GLFW_CURSOR_UNAVAILABLE error would be emitted each time the cursor
moved over the fallback decorations if the standard cursor shape
appropriate for that part was missing on the system.
These errors served no useful purpose and have been removed.
This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
Where available, the libdecor library is loaded at init and becomes the
preferred method for window decorations. On compositors that support
XDG decorations, libdecor in turn uses those. If not, libdecor has
a plug-in archtecture and may load additional libraries to either use
compositor-specific decorations or draw its own.
If necessary, support for libdecor can be disabled with the
GLFW_WAYLAND_LIBDECOR init hint. This is mostly in case some part of
the dynamic loading or duplication of header material added here turns
out to cause problems with future versions of libdecor-0.so.0.

This commit simplifies the detection of which element of a fallback
decorated window the pointer has entered. Instead of looping through
the list of windows, the user pointer of fallback decoration surfaces is
set to the GLFW window object.
This replaces (one case of) manual management of weak links between
windows and monitors, both objects with complex life times, with
wl_object pointers used as opaque key values.
This is in preparation for adding support for libdecor, which creates
its own proxies on our display. It will likely also be helpful to some
people using native access on Wayland.
This is partly based on the implementation of libdecor support in
PR #1693 by @ christianrauch.
If a window was initially fullscreen then it would not get an XDG
decoration object. If the window was later switched to windowed mode it
would then get fallback decorations instead of XDG ones.
