glfwGetKeyName¶
Returns the layout-specific name of the specified printable key.
This function returns the name of the specified printable key, encoded as UTF-8. This is typically the character that key would produce without any modifier keys, intended for displaying key bindings to the user. For dead keys, it is typically the diacritic it would add to a character.
Do not use this function for text input
. You will
break text input for many languages even if it happens to work for yours.
If the key is GLFW_KEY_UNKNOWN
, the scancode is used to identify the key,
otherwise the scancode is ignored. If you specify a non-printable key, or
GLFW_KEY_UNKNOWN
and a scancode that maps to a non-printable key, this
function returns NULL
but does not emit an error.
This behavior allows you to always pass in the arguments in the
key callback
without modification.
The printable keys are:
- GLFW_KEY_APOSTROPHE
- GLFW_KEY_COMMA
- GLFW_KEY_MINUS
- GLFW_KEY_PERIOD
- GLFW_KEY_SLASH
- GLFW_KEY_SEMICOLON
- GLFW_KEY_EQUAL
- GLFW_KEY_LEFT_BRACKET
- GLFW_KEY_RIGHT_BRACKET
- GLFW_KEY_BACKSLASH
- GLFW_KEY_WORLD_1
- GLFW_KEY_WORLD_2
- GLFW_KEY_0
to GLFW_KEY_9
- GLFW_KEY_A
to GLFW_KEY_Z
- GLFW_KEY_KP_0
to GLFW_KEY_KP_9
- GLFW_KEY_KP_DECIMAL
- GLFW_KEY_KP_DIVIDE
- GLFW_KEY_KP_MULTIPLY
- GLFW_KEY_KP_SUBTRACT
- GLFW_KEY_KP_ADD
- GLFW_KEY_KP_EQUAL
Names for printable keys depend on keyboard layout, while names for non-printable keys are the same across layouts but depend on the application language and should be localized along with other user interface text.
