= class Gtk::Object
Gtk::Object is the base class for all widgets, and for a few non-widget objects such as Gtk::Adjustment. Gtk::Object predates GLib::Object; non-widgets that derive from Gtk::Object rather than GLib::Object do so for backward compatibility reasons.
In Ruby/GTK, one of the difference between Gtk::Object and GLib::Object is the "destroy" signal, emitted by the Gtk::Object#destroy method. The "destroy" signal asks all code owning a reference to an object to release said reference. So, for example, if you call Gtk::Object#destroy on a Gtk::Window, Ruby/GTK will release it; if you call Gtk::Object#destroy on a Gtk::Button, then the button will be removed from its parent container and the parent container will release its reference to the button.
== super class
* ((<GLib::Object>))
== public instance methods
--- destroy
Emits the "destroy" signal notifying all reference holders that they should release the Gtk::Object.
--- flags
Gets the ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>)) for an object without directly accessing its members.
* Returns: the object whose flags are returned(((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>))).
--- flags=(flags)
Sets the ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>)) for an object without directly accessing its members.
* flags: ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>))
* Returns: flags
--- set_flags
Same as flags=.
* flags: ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>))
* Returns: self
--- unset_flags(flags)
Unsets the ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>)) for an object without directly accessing * flags: ((<GtkObjectFlags|Gtk::Object#GtkObjectFlags>))
* Returns: self
== constants
=== GtkObjectFlags
--- FLOATING
the object is orphaned.
--- IN_DESTRUCTION
the object is currently being destroyed. This is used internally by GTK+ to prevent reinvokations during destruction.
--- RESERVED_1
reserved for future use
--- RESERVED_2
reserved for future use
