	@doc:	spinbox
	@keyterms:
		spinbox object class,
	@title:
		spinbox class
	@type:
		class
	@short:
		Provides a simple spin button.
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		This widget allows the user to choose a value either by clicking the up/down buttons
		to increase/decrease the value currently displayed or by typing the value directly into the spin box.
	@functions:
		!fn: $setValue(<value:integer>)
		Sets the value of the spin box.[br]
		See also [classfnc]$value[/classfnc]()
		!fn: $setMinValue(<min_value:integer>)
		Sets the minimum value of the spin box.
		See also [classfnc]$MinValue[/classfnc]()
		!fn: $setMaxValue(<max_value:integer>)
		Sets the maximum value of the spin box.[br]
		See also [classfnc]$maxValue[/classfnc]()
		!fn: $setLineStep(<line_step:integer>)
		Sets the  line step: when the user uses the arrows to change the spin box's value the value will be
		incremented/decremented by the amount of the line step.
		See also [classfnc]$lineStep[/classfnc]()
		!fn: $setSpecialValueText(<text:string>)
		Sets the special-value text.
		If set, the spin box will display this text instead of a numeric value whenever the current value is equal to [classfnc]$minValue[/classfnc]().
		See also [classfnc]$setSpecialValueText[/classfnc]()
		!fn: $setPrefix(<text:string>)
		This property holds the spin box's prefix.[br]
		The prefix is prepended to the start of the displayed value.[br]
		Typical use is to display a unit of measurement or a currency symbol.
		See also [classfnc]$setSuffix[/classfnc]()
		!fn: $setSuffix(<text:string>);
		This property holds the suffix of the spin box.[br]
		The suffix is appended to the end of the displayed value.[br]
		See also [classfnc]$setPrefix[/classfnc]()
		!fn: <integer> $value()
		Returns the value of the spin box.
		See also [classfnc]$setValue[/classfnc]()
		!fn: <integer> $minValue
		Returns the minimum value of the spin box.
		See also [classfnc]$setMinValue[/classfnc]()
		!fn: <integer> $maxValue
		Returns the maximum value of the spin box.
		See also [classfnc]$setMaxValue[/classfnc]()
		!fn: <integer> $lineStep()
		Return the linestep.
		!fn: <string> $specialValueText()
		Returns the special-value text.
		See also [classfnc]$setSpecialValueText[/classfnc]()
		!fn: $valueChangedEvent(<new value:integer>)
		This function is called by the framework when the spin box value is changed and return the new slider value as its argument.[br]
		The default implementation emits the [classfnc]$valueChanged[/classfnc]() signal,
		so it is easy to handle the values from many spin boxes without reimplementing
		the [classfnc]$valueChangedEvent[/classfnc]() for every one.[br]
		Note: If you reimplement this function to catch the spin box value, you will have to emit the signal by yourself (if you still need it, obviously).
	@signals:
		!sg: $valueChanged()
		This signal is emitted by the default implementation of [classfnc]valueChangedEvent[/classfnc]().[br]
		If you reimplement that function you will have to emit the signal manually (if you still need it).
