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().
gchar* gdk_keyval_name (guint keyval); |
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_".
guint gdk_keyval_from_name (const gchar *keyval_name); |
Converts a key name to a key value.
gboolean gdk_keyval_is_upper (guint keyval); |
Returns TRUE if the given key value is in upper case.
gboolean gdk_keyval_is_lower (guint keyval); |
Returns TRUE if the given key value is in lower case.
guint gdk_keyval_to_upper (guint keyval); |
Converts a key value to upper case, if applicable.
