Class: Slider

LuxModule: gui

The slider is a handle than can be moved within some limits.

You can create and use a slider in this way:

 slider = Slider:new(100,20,100,20)
 function slider:onValueChanged (newvalue,oldvalue)
   print(newvalue,oldvalue)
 end
 Container.getRootContainer():add(slider)

The following skinssurface names are used by the slider class:

Vertical slider skin surfaces
* sliderv
* sliderv_pressed
* sliderv_hovered
* sliderv_focused
Horizontal slider skin surfaces
* sliderh
* sliderh_pressed
* sliderh_hovered
* sliderh_focused

Methods:

new (class, int x,y,w,h, [boolean vertical, [Skin2D, [Icon] ] ]): returns: (Slider)
Creates Slider with given bounds. If vertical is true the slider is vertical aligned.
mouseWheeled (Slider,MouseEvent): returns: ()
This function sets the sliderposition if the mousewheel was turned.
onKeyTyped (Slider,KeyEvent): returns: ()
Attached to Slider with a keylistener. Will react on arrow up/down/left/right keypresses and moves the slider.
onValueChanged (Slider, float newvalue,prevvalue): returns: ()
called if the slider position was changed. The values are always between 0 and 1. You can overload this function without calling the original overloaded function. This function is only called if the previous value is distinct from the new value.
setIncrement: (),(Slider, float inc) - Sets sliderincrement of slider. You could set the value directly by assigning a new value to the sliderincrement value, but you shouldn't chose values <=0 or >1 and you should update the sliderposition to its new value in case that the integermode is on and the value is hereby changed.
setIntegerMode: (),(Slider, boolean on) - switches IntegerMode on and of. In integermode, the values that are set are being rounded to even multiplies of the sliderincrement value.
setSliderPos (Slider): returns: (float pos)
get the position of the slider 0-1.
setSliderTo (Slider,x,y): returns: ()
sets the slider position nearest to a pixelposition given by x and y that are in local coordinates of the component.
sliderincrement: {[float]}=0.1 - increment of sliderposition. Can be set per slider. The increment value is used if the mousewheel or the arrow keys have been used.
