Trait containing all ShortcutTrigger methods.

Required Methods

fn to_label(&self, display: &impl IsA<Display>) -> GString

Gets textual representation for the given trigger.

This function is returning a translated string for presentation to end users for example in menu items or in help texts.

The @display in use may influence the resulting string in various forms, such as resolving hardware keycodes or by causing display-specific modifier names.

The form of the representation may change at any time and is not guaranteed to stay identical.

display

gdk::Display to print for

Returns

a new string

fn to_str(&self) -> GString

Prints the given trigger into a human-readable string.

This is a small wrapper around Gtk::ShortcutTrigger::print() to help when debugging.

Returns

a new string

fn trigger(&self, event: impl AsRef<Event>, enable_mnemonics: bool) -> KeyMatch

Checks if the given @event triggers @self.

event

the event to check

enable_mnemonics

true if mnemonics should trigger. Usually the value of this property is determined by checking that the passed in @event is a Key event and has the right modifiers set.

Returns

Whether the event triggered the shortcut
