Detailed Description

Triggers to track if shortcuts should be activated.

Gtk::ShortcutTrigger is the object used to track if a Gtk::Shortcut should be activated. For this purpose, trigger() can be called on a Gdk::Event.

ShortcutTriggers contain methods that allow easy presentation to end users as well as being printed for debugging.

All ShortcutTriggers are immutable, you can only specify their properties during construction. If you want to change a trigger, you have to replace it with a new one.

Member Function Documentation

compare()

int Gtk::ShortcutTrigger::compare

(

const Glib::RefPtr< const ShortcutTrigger > &

trigger2

)

const

The types of trigger1 and trigger2 are gconstpointer only to allow use of this function as a CompareFunc.

They must each be a Gtk::ShortcutTrigger.

Parameters

trigger2

A Gtk::ShortcutTrigger.

Returns

An integer less than, equal to, or greater than zero if trigger1 is found, respectively, to be less than, to match, or be greater than trigger2.

equal()

bool Gtk::ShortcutTrigger::equal

(

const Glib::RefPtr< const ShortcutTrigger > &

trigger2

)

const

Checks if trigger1 and trigger2 trigger under the same conditions.

The types of one and two are gconstpointer only to allow use of this function with HashTable. They must each be a Gtk::ShortcutTrigger.

Parameters

trigger2

A Gtk::ShortcutTrigger.

Returns

true if trigger1 and trigger2 are equal.

get_type()

static GType Gtk::ShortcutTrigger::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GtkShortcutTrigger * Gtk::ShortcutTrigger::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkShortcutTrigger * Gtk::ShortcutTrigger::gobj ( ) const

inline

Provides access to the underlying C GObject.

gobj_copy()

GtkShortcutTrigger * Gtk::ShortcutTrigger::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

operator=()

ShortcutTrigger & Gtk::ShortcutTrigger::operator= ( ShortcutTrigger &&  src )

noexcept

parse_string()

static Glib::RefPtr< ShortcutTrigger > Gtk::ShortcutTrigger::parse_string ( const Glib::ustring &  string )

static

Tries to parse the given string into a trigger.

On success, the parsed trigger is returned. When parsing failed, nullptr is returned.

The accepted strings are:

• never, for Gtk::NeverTrigger
• a string parsed by gtk_accelerator_parse(), for a Gtk::KeyvalTrigger, e.g. <Control>C
• underscore, followed by a single character, for Gtk::MnemonicTrigger, e.g. _l
• two valid trigger strings, separated by a | character, for a Gtk::AlternativeTrigger: <Control>q|<Control>w

Note that you will have to escape the < and > characters when specifying triggers in XML files, such as GtkBuilder ui files. Use < instead of < and > instead of >.

Parameters

string

The string to parse.

Returns

A new Gtk::ShortcutTrigger.

to_label()

Glib::ustring Gtk::ShortcutTrigger::to_label

(

const Glib::RefPtr< const Gdk::Display > &

display

)

const

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.

Parameters

display

Gdk::Display to print for.

Returns

A new string.

to_string()

Glib::ustring Gtk::ShortcutTrigger::to_string

(

)

const

Prints the given trigger into a human-readable string.

This is meant for debugging and logging. The form of the representation may change at any time and is not guaranteed to stay identical.

Returns

A new string.

trigger()

Gdk::KeyMatch Gtk::ShortcutTrigger::trigger	(	const Glib::RefPtr< const Gdk::Event > &	event,
		bool	enable_mnemonics
	)		const

Checks if the given event triggers self.

Parameters

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.

wrap()

Glib::RefPtr< Gtk::ShortcutTrigger > wrap ( GtkShortcutTrigger *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
