Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def consumed_modifiers : Gdk::ModifierType #

Extracts the consumed modifiers from a key event.

def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def is_modifier : Bool #

Extracts whether the key event is for a modifier key.


[View source]
def keycode : UInt32 #

Extracts the keycode from a key event.


[View source]
def keyval : UInt32 #

Extracts the keyval from a key event.


[View source]
def layout : UInt32 #

Extracts the layout from a key event.


[View source]
def level : UInt32 #

Extracts the shift level from a key event.


[View source]
def match(keyval : UInt32, modifiers : Gdk::ModifierType) : Bool #

Gets a keyval and modifier combination that will match the event.

See Gdk::KeyEvent#matches.


[View source]
def matches(keyval : UInt32, modifiers : Gdk::ModifierType) : Gdk::KeyMatch #

Matches a key event against a keyval and modifiers.

This is typically used to trigger keyboard shortcuts such as Ctrl-C.

Partial matches are possible where the combination matches if the currently active group is ignored.

Note that we ignore Caps Lock for matching.
