@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 new_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 fullscren on
|
||
|
|
that specific monitor.
|
||
|
|
|
||
|
|
|
||
|
|
@subsection news_30_unicode Unicode support
|
||
|
|
|
||
|
|
All string arguments to GLFW functions and all strings returned by GLFW 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 and EGL 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 currently only provides an EGL implementation.
|
||
|
|
|
||
|
|
GLFW now has an (experimental) EGL context creation backend, which can be
|
||
|
|
selected through CMake options.
|
||
|
|
|
||
|
|
|
||
|
|
@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 object 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 object has a callback for iconification and restoration events, which is
|
||
|
|
set with @ref glfwSetWindowIconifyCallback.
|
||
|
|
|
||
|
|
|
||
|
|
@subsection news_30_wndposfun Window position callback
|
||
|
|
|
||
|
|
Each window object 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
|
||
|
|
|
||
|
|
Windows now have a callback for focus events, which is set with @ref
|
||
|
|
glfwSetWindowFocusCallback.
|
||
|
|
|
||
|
|
|
||
|
|
@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 offscreen rendering in a way compatible with most drivers, as
|
||
|
|
well as moving a window to a specific position before showing it.
