InputEventKey

Inherits: InputEventWithModifiers < InputEventFromWindow < InputEvent < Resource < RefCounted < Object

Represents a key on a keyboard being pressed or released.

Description

An input event for keys on a keyboard. Supports key presses, key releases and echo events. It can also be received in Node._unhandled_key_input.

Note: Events received from the keyboard usually have all properties set. Event mappings should have only one of the keycode, physical_keycode or unicode set.

When events are compared, properties are checked in the following priority - keycode, physical_keycode and unicode. Events with the first matching value will be considered equal.

Property Descriptions

bool echo = false

  • void set_echo ( bool value )

  • bool is_echo ( )

If true, the key was already pressed before this event. It means the user is holding the key down.

Key key_label = 0

  • void set_key_label ( Key value )

  • Key get_key_label ( )

Represents the localized label printed on the key in the current keyboard layout, which corresponds to one of the Key constants or any valid Unicode character.

For keyboard layouts with a single label on the key, it is equivalent to keycode.

To get a human-readable representation of the InputEventKey, use OS.get_keycode_string(event.key_label) where event is the InputEventKey.

Key keycode = 0

  • void set_keycode ( Key value )

  • Key get_keycode ( )

Latin label printed on the key in the current keyboard layout, which corresponds to one of the Key constants.

To get a human-readable representation of the InputEventKey, use OS.get_keycode_string(event.keycode) where event is the InputEventKey.

+-----+ +-----+
| Q   | | Q   | - "Q" - keycode
|   Й | |  ض | - "Й" and "ض" - key_label

Key physical_keycode = 0

  • void set_physical_keycode ( Key value )

  • Key get_physical_keycode ( )

Represents the physical location of a key on the 101/102-key US QWERTY keyboard, which corresponds to one of the Key constants.

To get a human-readable representation of the InputEventKey, use OS.get_keycode_string(event.keycode) where event is the InputEventKey.

bool pressed = false

  • void set_pressed ( bool value )

  • bool is_pressed
