@doc:	slider
	@keyterms:
		slider object class
	@title:
		slider class
	@type:
		class
	@short:
		The slider widget provides a vertical or horizontal slider.
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		The slider is the classic widget for controlling a bounded value.[br]
		It lets the user move a slider along a horizontal or vertical groove [br]
		and translates the slider's position into an integer value within the legal range.[/classfnc]()
	@functions:
		!fn: $setOrientation(<orientation:string>)
		Sets the slider's orientation.[br]
		Orientation value can be "Horizontal" or "Vertical".
		!fn: $setTracking(<bTracking:boolean>)
		Sets whether slider tracking is enabled to enable.[br]
		Value can be 1 or 0.
		!fn: $setMaxValue(<value:integer>)
		Sets maximum value for slider's range.
		!fn: $setMinValue(<minv_value:integer>)
		Sets minimum value for slider's range.
		!fn: $setLineStep(<line_step:integer>)
		Sets the  line step to <line_step>.
		!fn: $setPageStep(<page_step:integer>)
		Sets the  page step to <page_step>.
		!fn: $setTickmarks(<tick_marks:string>)
		Sets the tickmark settings for this slider.[br]
		Values are:[br]
		NoMarks - do not draw any tickmarks.[br]
		Both - draw tickmarks on both sides of the groove.[br]
		Above - draw tickmarks above the (horizontal) slider[br]
		Below - draw tickmarks below the (horizontal) slider[br]
		Left - draw tickmarks to the left of the (vertical) slider[br]
		Right - draw tickmarks to the right of the (vertical) slider
		!fn: $setTickInterval(<value>)
		Sets the interval between tickmarks.
		!fn: <integer> $value()
		Returns slider value.
		!fn: <integer> $minValue()
		Returns slider minValue.
		!fn: <integer> $maxValue()
		Returns slider maxValue.
		!fn: <integer> $lineStep()
		Returns slider lineStep value.
		!fn: <integer>$pageStep()
		Returns slider pageStep value.
		!fn: $valueChangedEvent(<new slider value:integer>)
		This function is called by the framework when the slider value is changed and return the new slider value as its argument.[br]
		The default implementation emits the [classfnc]$valueChanged[/classfnc]() signal,
		so it is easy to handle the values from many sliders without reimplementing
		the [classfnc]$valueChangedEvent[/classfnc]() for every one.[br]
		Note: If you reimplement this function to catch the slider 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).
