Having one way to retrieve the cursor position and another (more verbose) way to retrieve the monitor position is inconsistent. Having them both work the same way is the least surprising thing. The expected glfwGetMonitorSize function gets an added Physical in its name so users won't confuse it with glfwGetVideoMode.

|

|

* The @ref GLFW_CLIENT_API hint specifies which client API to create the

|
|
* GLFW_OPENGL_ES_API.
|
|
*
|
|
* The @ref GLFW_CONTEXT_VERSION_MAJOR and @ref GLFW_CONTEXT_VERSION_MINOR
|
|
* hints specify the client API version that the created context must be
|
|
* compatible with.
|
|
*
|
|
* For OpenGL, these hints are @em not hard constraints, as they don't have to
|
|
* match exactly, but @ref glfwCreateWindow will still fail if the resulting
|
|
* OpenGL version is less than the one requested. It is therefore perfectly
|
|
* safe to use the default of version 1.0 for legacy code and you will still
|
|
* get backwards-compatible contexts of version 3.0 and above when available.
|
|
*
|
|
* For OpenGL ES, these hints are hard constraints, as there is no backward
|
|
* compatibility between OpenGL ES versions.
|
|
*
|
|
* If an OpenGL context is requested, the @ref GLFW_OPENGL_FORWARD_COMPAT hint
|
|
* specifies whether the OpenGL context should be forward-compatible, i.e. one
|
|
* where all functionality deprecated in the requested version of OpenGL is
|
|
* removed. This may only be used if the requested OpenGL version is 3.0 or
|
|
* above. If another client API is requested, this hint is ignored.
|
|
*
|
|
* If an OpenGL context is requested, the @ref GLFW_OPENGL_DEBUG_CONTEXT hint
|
|
* specifies whether to create a debug OpenGL context, which may have
|
|
* additional error and performance issue reporting functionality. If another
|
|
* client API is requested, this hint is ignored.
|
|
*
|
|
* If an OpenGL context is requested, the @ref GLFW_OPENGL_PROFILE hint
|
|
* specifies which OpenGL profile to create the context for. Possible values
|
|
* are one of @ref GLFW_OPENGL_CORE_PROFILE or @ref GLFW_OPENGL_COMPAT_PROFILE,
|
|
* or @ref GLFW_OPENGL_NO_PROFILE to not request a specific profile. If
|
|
* requesting an OpenGL version below 3.2, @ref GLFW_OPENGL_NO_PROFILE must be
|
|
* used. If another client API is requested, this hint is ignored.
|
|
*
|
|
* The @ref GLFW_CONTEXT_ROBUSTNESS hint specifies the robustness strategy to
|
|
* be used by the context. This can be one of @ref GLFW_NO_RESET_NOTIFICATION
|
|
* or @ref GLFW_LOSE_CONTEXT_ON_RESET, or @ref GLFW_NO_ROBUSTNESS to not
|
|
* request a robustness strategy.
|
|
*
|
|
* @par Window hints
|
|
*
|
|
* The @ref GLFW_RESIZABLE hint specifies whether the window will be resizable
|
|
* by the user. The window will still be resizable using the @ref
|
|
* glfwSetWindowSize function. This hint is ignored for fullscreen windows.
|
|
*
|
|
* The @ref GLFW_VISIBLE hint specifies whether the window will be initially
|
|
* visible. This hint is ignored for fullscreen windows.
|
|
*
|
|
* The @ref GLFW_POSITION_X and @ref GLFW_POSITION_Y hints specify the initial
