type

The gdk-event-type type of the event, one of the values :key-press, :key-release.

window

The gdk-window object which received the event.

send-event

True if the event was sent explicitly.

time

An unsigned integer with the time of the event in milliseconds.

state

The gdk-modifier-type bit-mask representing the state of the modifier keys, e.g. the Control, Shift and Alt keys, and the pointer buttons.

keyval

The key that was pressed or released. See the gdk/gdkkeysyms.h header file for a complete list of GDK key codes.

length

An integer with the length of the string field.

string

A string containing an approximation of the text that would result from this keypress. The only correct way to handle text input is using input methods, see the gtk-im-context API, so this field is deprecated and should never be used. The gdk-unicode-to-keyval function provides a non-deprecated way of getting an approximate translation for a key. The string field is encoded in the encoding of the current locale. Note this for backwards compatibility: strings in GTK and GDK are typically in UTF-8 and NUL-terminated. In some cases, the translation of the key code will be a single NUL byte, in which case looking at length is necessary to distinguish it from an empty translation.

hardware-keycode

An unsigned integer with the raw code of the key that was pressed or released.

group

An unsigned integer with the keyboard group.

is-modifier

A flag that indicates if the hardware-keycode field is mapped to a modifier.
