Key Values
functions for manipulating keyboard codes.
Key values are the codes which are sent whenever a key is pressed or released.
They appear in the keyval field of the
#GdkEventKey structure, which is passed to signal handlers for the
"key-press-event" and "key-release-event" signals.
The complete list of key values can be found in the <gdk/gdkkeysyms.h>
header file.
Key values can be converted into a string representation using
gdk_keyval_name(). The reverse function, converting a string to a key value,
is provided by gdk_keyval_from_name().
The case of key values can be determined using gdk_keyval_is_upper() and
gdk_keyval_is_lower(). Key values can be converted to upper or lower case
using gdk_keyval_to_upper() and gdk_keyval_to_lower().

@Returns:
Converts a key value into a symbolic name.
The names are the same as those in the <gdk/gdkkeysyms.h> header file
but without the leading "GDK_".
@keyval: a key value.
@Returns: a string containing the name of the key, or NULL if @keyval is not
a valid key. The string should not be modified.
Converts a key name to a key value.
@keyval_name: a key name.
@Returns: the corresponding key value, or %GDK_VoidSymbol if the key name is
not a valid key.
@symbol:
@lower:
@upper:
Converts a key value to upper case, if applicable.
@keyval: a key value.
@Returns: the upper case form of @keyval, or @keyval itself if it is already
in upper case or it is not subject to case conversion.
Converts a key value to lower case, if applicable.
@keyval: a key value.
@Returns: the lower case form of @keyval, or @keyval itself if it is already
in lower case or it is not subject to case conversion.
Returns TRUE if the given key value is in upper case.
@keyval: a key value.
@Returns: TRUE if @keyval is in upper case, or if @keyval is not subject to
case conversion.
Returns TRUE if the given key value is in lower case.
@keyval: a key value.
@Returns: TRUE if @keyval is in lower case, or if @keyval is not subject to
case conversion.
