@section news_31 New features in version 3.1
|
|
|
|
@subsection news_31_cursor Custom system cursor support
|
|
|
|
GLFW now supports creating and setting both custom and standard system cursors.
|
|
They can be created with @ref glfwCreateCursor or @ref glfwCreateStandardCursor,
|
|
set with @ref glfwSetCursor and destroyed with @ref glfwDestroyCursor.
|
|
|
|
|
|
@subsection news_31_drop File drop event support
|
|
|
|
GLFW now provides a callback for receiving the paths of files dropped onto GLFW
|
|
windows. The callback is set with @ref glfwSetDropCallback.
|
|
|
|
|
|
@subsection news_31_emptyevent Main thread waking support
|
|
|
|
GLFW now provides the @ref glfwPostEmptyEvent function for posting an empty
|
|
event from another thread to the main thread event queue, causing @ref
|
|
glfwWaitEvents to return.
|
|
|
|
|
|
@subsection news_31_framesize Window frame size query
|
|
|
|
GLFW now supports querying the size, on each side, of the frame around the
|
|
client area of a window, with @ref glfwGetWindowFrameSize.
|
|
|
|
|
|
@subsection news_31_autoiconify Multi-monitor installation support
|
|
|
|
GLFW now supports disabling auto-iconification of full screen windows with
|
|
the [GLFW_AUTO_ICONIFY](@ref window_hints_wnd) window hint. This is intended
|
|
for people building multi-monitor installations, where you need windows to stay
|
|
in full screen despite losing focus.
|
|
|
|
|
|
@subsection news_31_floating Floating windows
|
|
|
|
GLFW now supports floating windows, also called topmost or always on top, for
|
|
easier debugging with the [GLFW_FLOATING](@ref window_hints_wnd) window hint.
|
|
|
|
|
|
@subsection news_31_focused Initially unfocused windows
|
|
|
|
GLFW now supports preventing a windowed mode window from gaining input focus on
|
|
creation, with the [GLFW_FOCUSED](@ref window_hints_wnd) window hint.
|
|
|
|
|
|
@subsection news_31_charmods Character with modifiers callback
|
|
|
|
GLFW now provides a callback for character events with modifier key bits. The
|
|
callback is set with @ref glfwSetCharModsCallback. Unlike the regular character
|
|
callback, this will report character events that will not result in a character
|
|
being input, for example if the Control key is held down.
|
|
|
|
|
|
@subsection news_31_release Context release behavior support
|
|
|
|
GLFW now supports controlling whether the pipeline is flushed when a context is
|
|
made non-current, with the
|
|
[GLFW_CONTEXT_RELEASE_BEHAVIOR](@ref window_hints_ctx) window hint, provided the
|
|
machine supports the `GL_KHR_context_flush_control` extension.
|
|
|
|
|
|
@subsection news_31_single Single buffering support
|
|
|
|
GLFW now supports the creation of single buffered windows, with the
|
|
[GLFW_DOUBLEBUFFER](@ref window_hints_fb) window hint.
|
|
|
|
|
|
@subsection news_31_egl Stable EGL support
|
|
|
|
The support for EGL is now stable, successfully running on PandaBoards, Mesa,
|
|
ANGLE, Wayland, AMD EGL and others.
|
|
|
|
|
|
@section news_30 New features in version 3.0
|
|
|
|
@subsection news_30_cmake CMake build system
|
|
|
|
GLFW now uses the CMake build system instead of the various makefiles and
|
|
project files used by earlier versions. CMake is available for all platforms
|
|
supported by GLFW, is present in most package systems and can generate
|
|
makefiles and/or project files for most popular development environments.
|
|
|
|
For more information on how to use CMake, see the
|
|
[CMake manual](http://cmake.org/cmake/help/documentation.html).
|
|
|
|
|
|
@subsection news_30_multiwnd Multi-window support
|
|
|
|
GLFW now supports the creation of multiple windows, each with their own OpenGL
|
|
or OpenGL ES context, and all window functions now take a window handle. Event
|
|
callbacks are now per-window and are provided with the handle of the window that
|
|
received the event. The @ref glfwMakeContextCurrent function has been added to
|
|
select which context is current on a given thread.
|
|
|
|
|
|
@subsection news_30_multimon Multi-monitor support
|
|
|
|
GLFW now explicitly supports multiple monitors. They can be enumerated with
|
|
@ref glfwGetMonitors, queried with @ref glfwGetVideoModes, @ref
|
|
glfwGetMonitorPos, @ref glfwGetMonitorName and @ref glfwGetMonitorPhysicalSize,
|
|
and specified at window creation to make the newly created window full screen on
|
|
that specific monitor.
|
|
|
|
|
|
@subsection news_30_unicode Unicode support
|
|
|
|
All string arguments to GLFW functions and all strings returned by GLFW now use
|
|
the UTF-8 encoding. This includes the window title, error string, clipboard
|
|
text, monitor and joystick names as well as the extension function arguments (as
|
|
ASCII is a subset of UTF-8).
|
|
|
|
|
|
@subsection news_30_clipboard Clipboard text I/O
|
|
|
|
GLFW now supports reading and writing plain text to and from the system
|
|
clipboard, with the @ref glfwGetClipboardString and @ref glfwSetClipboardString
|
|
functions.
|
|
|
|
|
|
@subsection news_30_gamma Gamma ramp support
|
|
|
|
GLFW now supports setting and reading back the gamma ramp of monitors, with the
|
|
@ref glfwGetGammaRamp and @ref glfwSetGammaRamp functions. There is also @ref
|
|
glfwSetGamma, which generates a ramp from a gamma value and then sets it.
|
|
|
|
|
|
@subsection news_30_gles OpenGL ES support
|
|
|
|
GLFW now supports the creation of OpenGL ES contexts, by setting the
|
|
`GLFW_CLIENT_API` window hint to `GLFW_OPENGL_ES_API`, where creation of such
|
|
contexts are supported. Note that GLFW _does not implement_ OpenGL ES, so your
|
|
driver must provide support in a way usable by GLFW. Modern nVidia and Intel
|
|
drivers support creation of OpenGL ES context using the GLX and WGL APIs, while
|
|
AMD provides an EGL implementation instead.
|
|
|
|
|
|
@subsection news_30_egl (Experimental) EGL support
|
|
|
|
GLFW now has an experimental EGL context creation back end that can be selected
|
|
through CMake options.
|
|
|
|
|
|
@subsection news_30_hidpi High-DPI support
|
|
|
|
GLFW now supports high-DPI monitors on both Windows and OS X, giving windows full
|
|
resolution framebuffers where other UI elements are scaled up. To achieve this,
|
|
@ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have been
|
|
added. These work with pixels, while the rest of the GLFW API works with screen
|
|
coordinates. This is important as OpenGL uses pixels, not screen coordinates.
|
|
|
|
|
|
@subsection news_30_error Error callback
|
|
|
|
GLFW now has an error callback, which can provide your application with much
|
|
more detailed diagnostics than was previously possible. The callback is passed
|
|
an error code and a description string.
|
|
|
|
|
|
@subsection news_30_wndptr Per-window user pointer
|
|
|
|
Each window now has a user-defined pointer, retrieved with @ref
|
|
glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it
|
|
easier to integrate GLFW into C++ code.
|
|
|
|
|
|
@subsection news_30_iconifyfun Window iconification callback
|
|
|
|
Each window now has a callback for iconification and restoration events,
|
|
which is set with @ref glfwSetWindowIconifyCallback.
|
|
|
|
|
|
@subsection news_30_wndposfun Window position callback
|
|
|
|
Each window now has a callback for position events, which is set with @ref
|
|
glfwSetWindowPosCallback.
|
|
|
|
|
|
@subsection news_30_wndpos Window position query
|
|
|
|
The position of a window can now be retrieved using @ref glfwGetWindowPos.
|
|
|
|
|
|
@subsection news_30_focusfun Window focus callback
|
|
|
|
Each windows now has a callback for focus events, which is set with @ref
|
|
glfwSetWindowFocusCallback.
|
|
|
|
|
|
@subsection news_30_enterleave Cursor enter/leave callback
|
|
|
|
Each window now has a callback for when the mouse cursor enters or leaves its
|
|
client area, which is set with @ref glfwSetCursorEnterCallback.
|
|
|
|
|
|
@subsection news_30_wndtitle Initial window title
|
|
|
|
The title of a window is now specified at creation time, as one of the arguments
|
|
to @ref glfwCreateWindow.
|
|
|
|
|
|
@subsection news_30_hidden Hidden windows
|
|
|
|
Windows can now be hidden with @ref glfwHideWindow, shown using @ref
|
|
glfwShowWindow and created initially hidden with the `GLFW_VISIBLE` window hint.
|
|
This allows for off-screen rendering in a way compatible with most drivers, as
|
|
well as moving a window to a specific position before showing it.
|
|
|
|
|
|
@subsection news_30_undecorated Undecorated windows
|
|
|
|
Windowed mode windows can now be created without decorations, i.e. things like
|
|
a frame, a title bar, with the `GLFW_DECORATED` window hint. This allows for
|
|
the creation of things like splash screens.
|
|
|
|
|
|
@subsection news_30_keymods Modifier key bit masks
|
|
|
|
[Modifier key bit mask](@ref mods) parameters have been added to the
|
|
[mouse button](@ref GLFWmousebuttonfun) and [key](@ref GLFWkeyfun) callbacks.
|
|
|
|
|
|
@subsection news_30_scancode Platform-specific scancodes
|
|
|
|
A scancode parameter has been added to the [key callback](@ref GLFWkeyfun). Keys
|
|
that don't have a [key token](@ref keys) still get passed on with the key
|
|
parameter set to `GLFW_KEY_UNKNOWN`. These scancodes will vary between machines
|
|
and are intended to be used for key bindings.
|
|
|
|
|
|
@subsection news_30_jsname Joystick names
|
|
|
|
The name of a joystick can now be retrieved using @ref glfwGetJoystickName.
|
|
|
|
|
|
@subsection news_30_doxygen Doxygen documentation
|
|
|
|
You are reading it.
