Instance Method Details

#ease_out_cubic(t) ⇒ Float

Computes the ease out for a value.

Parameters:

  • t (Float) —

    the term

Returns:

  • (Float) —

    the ease out for t

#enum_value_row_name(value, user_data) ⇒ String

Returns the name of a [classEnumValueObject].

This is a default implementation of [callbackComboRowGetEnumValueNameFunc] to be used with [methodComboRow.set_for_enum]. If the enumeration has a nickname, it will return it, otherwise it will return its name.

Parameters:

  • value (Handy::EnumValueObject) —

    the value from the enum from which to get a name

  • user_data (GObject) —

    unused user data

Returns:

  • (String) —

    a displayable name that represents value

#get_enable_animations(widget) ⇒ Boolean

Checks whether animations are enabled for widget.

This should be used when implementing an animated widget to know whether to animate it or not.

Parameters:

  • widget (Gtk::Widget) —

    a widget

Returns:

  • (Boolean) —

    whether animations are enabled for widget

#init ⇒ nil

Initializes Libhandy.

Call this function just after initializing GTK, if you are using [classGtk.Application] it means it must be called when the [signalGio.Application::startup] signal is emitted.

If Libhandy has already been initialized, the function will simply return.

This makes sure translations, types, themes, and icons for the Handy library are set up properly.

Returns:

  • (nil)
