= module Gtk
Gtk module includes methods as Library initialization, main event loop, events, and standard constants.
Before using Ruby/GTK, you need to initialize it;
initialization connects to the window system display,
and parses some standard command line arguments.
The Gtk.init function initializes Ruby/GTK.
Like all GUI toolkits, Ruby/GTK uses an event-driven programming model.
When the user is doing nothing, Ruby/GTK sits in the main loop and waits for input.
If the user performs some action - say, a mouse click - then the main loop "wakes up" and delivers an event to Ruby/GTK.
Ruby/GTK forwards the event to one or more widgets.
When widgets receive an event, they frequently emit one or more signals.
Signals notify your program that "something interesting happened" by invoking blocks you've connected to the signal with GLib::Instantiable#signal_connect.
Blocks connected to a signal are often termed callbacks.
When your callbacks are invoked, you would typically take some action - for example, when an Open button is clicked you might display a Gtk::FileSelectionDialog.
After a callback finishes, Ruby/GTK will return to the main loop and await more user input.
== module functions
--- Gtk.init(argv = ARGV)
Call this function before using any other GTK+ functions in your GUI applications. It will initialize everything needed to operate the toolkit and parses some standard command line options.
argv are adjusted accordingly so your own code will never see those standard arguments.
Note:
This function will throw RuntimeError if it was unable to initialize the GUI for some reason.
* argv: the ARGV value. Any parameters understood by Gtk.init are stripped before return.
* Returns: self
--- Gtk.main
Runs the main loop until Gtk.main_quit is called. You can nest calls to Gtk.main.
In that case Gtk.main_quit will make the innermost invocation of the main loop return.
--- Gtk.main_level
--- Gtk.main_quit
Makes the innermost invocation of the main loop return when it regains control.

=== GtkWindowType
A Gtk::Window can be one of these types. Most things you'd consider a "window" should have type Gtk::WINDOW_TOPLEVEL; windows with this type are managed by the window manager and have a frame by default (call Gtk::Window#set_decorated to toggle the frame). Windows with type Gtk::WINDOW_POPUP are ignored by the window manager; window manager keybindings won't work on them, the window manager won't decorate the window with a frame, many GTK+ features that rely on the window manager will not work (e.g. resize grips and maximization/minimization). Gtk::WINDOW_POPUP is used to implement widgets such as Gtk::Menu or tooltips that you normally don't think of as windows per se. Nearly all windows should be Gtk::WINDOW_TOPLEVEL. In particular, do not use Gtk::WINDOW_POPUP just to turn off the window borders; use Gtk::Window#set_decorated for that.

--- WINDOW_POPUP
A special window such as a tooltip.
=== GtkSortType
Determines the direction of a sort.
--- SORT_ASCENDING
