		class
	@short:
		Base class for all widgets
	@inherits:
		[class]object[/class]
	@description:
		This object class is the representation of a widget.
		All the other widget-type classes inherit from this one.
	@functions:
		!fn: $show()
		Shows this widget and the child items.
		See also [classfnc]$hide[/classfnc]() and [classfnc]$isVisible[/classfnc].

		!fn: $move(<x_or_array>[,<y>])
		Moves this widget to the coordinate <x> and <y> relative to its
		parent widget (or the desktop if this widget is a toplevel one).
		This is equivalent to [classfnc]$setGeometry[/classfnc](<x>,<y>,
		[classfnc]$width[/classfnc](),[classfnc]$height[/classfnc]()).
		!fn: $resize(<w_or_array>,[height])
		Changes the widget's width to <width> and height to <height>.
		See also [classfnc]$setGeometry[/classfnc]().
		!fn: $isEnabled()

		widget is a toplevel one.
		!fn: $backgroundColor()
		Returns the background color of this widget in hexadecimal
		HTML-like format. For example, for a black background you will get
		the string "000000", for a red one, "FF0000", for a white one

		specify colors in HTML pages). The first two digits specify
		the RED component, the third and fourth digit specify the GREEN component
		and the last two specify the BLUE component.
		For example "FFFF00" means full red, full green and no blue that gives
		a yellow color, "808000" designates a brown color (dark yellow),
		"A000A0" is a kind of violet.
		- array(red:integer,green:integer,blue:integer)

		!fn: $setMouseTracking(<bool>)
		Enables or disables the mouse tracking if <bool> is [b]1[/b] or [b]0[/b] respectively.

		the cursor is in this widget. <button> is [b]0[/b] if the pressed button

		The <x> and <y> coordinates are relative to this widget upper-left corner
		and are expressed in pixels.

		The <x> and <y> coordinates are relative to this widget upper-left corner
		and are expressed in pixels.

		of this event. The default implementation does nothing.
		!fn: $mouseDoubleClickEvent(<button>,<x>,<y>)

		the cursor is in this widget. <button> is [b]0[/b]if the double clicked button
		is the left one, [b]1[/b] if the button is the right one and [b]2[/b] if it is the middle one.
		The <x> and <y> coordinates are relative to this widget upper-left corner
		and are expressed in pixels.
		If you call [i][cmd]setreturn[/cmd] [b]1[/b][/i] you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $mouseMoveEvent(<x>,<y>)
		This function is called when the mouse cursor moves inside this widget.
		The <x> and <y> coordinates are relative to this widget upper-left corner
		and are expressed in pixels.
		If you call "[cmd]return[/cmd]$true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $focusInEvent()
		This function is called when this widget gains keyboard focus.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $focusOutEvent()
		This function is called when this widget looses keyboard focus.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $mouseLeaveEvent()
		This function is called when the mouse leaves this widget.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $mouseEnterEvent()

		of this event. The default implementation does nothing.
		!fn: $showEvent()
		This function is called when this widget is being shown.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $hideEvent()
		This function is called when this widget is being hidden.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $closeEvent()
		This function is called when this widget is going to be closed.
		If you call "[cmd]return[/cmd] $true" you will ignore the close event.
		The default implementation does nothing.
		!fn: $resizeEvent()
		This function is called immediately after this widget has been resized.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $moveEvent()
		This function is called immediately after this widget has been moved.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event. The default implementation does nothing.
		!fn: $paintEvent(<painter:h_object>,<rect_x:integer>,<rect_y:integer>,<width:integer>,<height:integer>)
		This event handler can be reimplemented to repaint all or part of the widget.
		It's needed by the Painter class.
		It's very useful for drawing flicker free animations or low level special graphic effects.
		The framework will pass as parameter a [class]painter[/class]object. You don't need to begin/end/delete the painter.
		If you call "[cmd]return[/cmd] $true" you will stop the internal processing
		of this event.
		The default implementation does nothing.
		!fn: $setParent(<widget_object:parent>)
		Sets the parent of the widget to parent

		Sets the background image for this widget.
		See the [doc:image_id]image identifier[/doc] documentation for the explanation
		of the <image_id> parameter.
		For some kind of widgets, setting a background pixmap may have no effect or
		have strange results. Experiment with it.
		To unset the background image call [classfnc]$setBackgroundColor[/classfnc]
		!fn: $setFont(<family:string>,<size:integer>[,<style1:string>, <style2:string>, ...])
