Name
Key Values -- functions for manipulating keyboard codes.
Description
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().
Details
gdk_keyval_name ()
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_".
gdk_keyval_from_name ()
guint gdk_keyval_from_name (const gchar *keyval_name); |
Converts a key name to a key value.
gdk_keyval_is_upper ()
Returns TRUE if the given key value is in upper case.
gdk_keyval_is_lower ()
Returns TRUE if the given key value is in lower case.
gdk_keyval_convert_case ()
gdk_keyval_to_upper ()
Converts a key value to upper case, if applicable.
gdk_keyval_to_lower ()
Converts a key value to lower case, if applicable.
gdk_keyval_to_unicode ()
Convert from a GDK key symbol to the corresponding ISO10646 (Unicode)
character.
gdk_unicode_to_keyval ()
Convert from a ISO10646 character to a key symbol.
