		toolbutton object class,
	@title:
		toolbutton class
	@type:
		class

	@functions:
		!fn:$setImage(<icon_id:string>)
		Sets the image for this button.
		!fn:$setUsesBigPixmap(<bEnabled:boolean>)
		Sets whether this toolbutton uses big pixmaps to enable.
		!fn:$usesBigPixmap(<bEnabled:boolean>)
		This property holds whether this toolbutton uses big pixmaps.
		!fn:setUsesTextLabel(<bEnabled:boolean>)
		Sets whether the toolbutton show a texlabel below the pixmap of the button.
		!fn:$usesTextLabel()
		Return 1 if the setUsesTextLabel is enabled, otherwise return 0.
		!fn:$setTextLabel(<text:String>,[tooltip:string])
		Sets the label of this button to <text> and automatically sets it as a tool tip if <tip> is true.
		!fn:<string> $textLabel()
		Returns the label of tthe button.
		!fn:$setAutoRaise(<bAutoraise:boolean>)
		Sets whether auto-raising is enabled.
		!fn:<boolean> $autoRaise()
		Returns 1 if autoRaise is enabled, otherwise returns 0.
		!fn:$setToggleButton(<bToggle:boolean>)
		Sets whether the tool button is a toggle button 1 enable, 0 disable.
		!fn:<boolean> $toggle()
		Toggles the state of the tool button.
		!fn:$setOn(<bEnabled:boolean>)
		Sets whether the tool button is on to the bool value: 1 enable, 0 disable.
		!fn:$setPopup (<popupmenu:object>)
		Associates the given <popupmenu> with this tool button.
		!fn:$openPopup()
		Opens the associated popup menu. If there is no such menu, this function does nothing.
		!fn:setTextPosition(<text_position:string>)
		Sets the position of the tool button's textLabel in relation to the tool button's icon.[br]
		Valid texpos values are:[br]
		- BesideIcon : The text appears beside the icon.[br]
		- BelowIcon  : The text appears below the icon.
		!fn:<string> $textPosition()
		Returns the position of the text label of this button.
		!fn: $clickEvent()
		This function is called when the toolbutton is clicked.[br]
		You can reimplement it to handle the user click events.[br]
		The default implementation emits the [classfnc]$clicked[/classfnc]() signal.
	@signals:
		!sg: $clicked()
		This signal is emitted by the default implementation of [classfnc]$clickEvent[/classfnc]().[br]
