	@description:
		This class represents a window in a KVIrc frame.
		Regardless of the parent object passed, the window will be always
		a [i]physical[/i] child of the frame window: you can't embed a window object
		inside a widget or another window. The parent object will just [i]own[/i] this
		window object and eventually destroy it when it dies.
		This class can manage only a single central child widget that must
		be set with $setCentralWidget().
		The central widget [b]must[/b] be set before you initially call show()
