This instruction guide may be very useful as an advanced reference guide, but for C4D Scrollbar beginners we recommend viewing the Simple Instruction and Example page and the
Simple Instruction [ Text ] page. This guide includes only option functionality for skilled Actionscript programmers.
[b]Public Methods:
scrollTo(position ,allowEase=false)
Return Value: None
Parameters
position:Number - numeric value that signifies _y position (or _x for horizontal) to move the Content MC Instance to
position:String - setting position to "Top" (case sensitive) will move the Content MC Instance to the Mask MC Instance
allowEase:Boolean - When set true scrolls content to position at the Easing property specified movement speed.
addAnchor(position)
Return Value: None
Parameters
position:Number - adds a numeric value to the anchor array. For more details see Anchor Positions in component parameters.
Public Properties
_anchors - array of anchor positions. For more details see Anchor Positions in component parameters.
Events:
Events are listener functions.
Component events should be used if available instead of events associated with scrollbar elements.
Example of use:
componentInstanceName.onEventName = function(parameter1, parameter2,...){
//event code
}
onUpPress() - Up scroller element onPress event
onUpRelease() - Up scroller element onRelease event
onUpRollOver() - Up scroller element onRollOver event
onUpRollOut() - Up scroller element onRollOut event
onUpReleaseOutside() - Up scroller element onReleaseOutside event
onDownPress() - Down scroller element onPress event
onDownRelease() - Down scroller element onRelease event
onDownRollOver() - Down scroller element onRollOver event
onDownRollOut() - Down scroller element onRollOut event
onDownReleaseOutside() - Down scroller element onReleaseOutside event
onTrackPress() - Track scroller element onPress event
onTrackRelease() - Track scroller element onRelease event
onTrackRollOver() - Track scroller element onRollOver event
onTrackRollOut() - Track scroller element onRollOut event
onTrackReleaseOutside() - Track scroller element onReleaseOutside event
onScrollMouseWheel(delta:Number) - Event triggered by Mousewheel change by numeric value delta
onScrollContentChanged() - Event triggered when Content MC Instance _height (or _width for horizontal) changes
onScrollThumbResized(newThumbSize:Number)
- if Resizeable Thumb component parameter is set true this event will trigger when the thumbsize changes.
newThumbSize is the new numeric value of the _height (or _width for horizontal) of the Thumb scrollbar element
onScrollUpdate() - triggered every enterFrame if the Content MC Instance _height (or _width for horizontal) is larger than that of the Mask MC Instance.
Advanced Properties
_cursor - This private variable is accessable from within the component events. It reflects a number n: 1>=n<=10000 that is represents the percentage of scrolling n=1 being the content is at the top of the scrollwindow n=10000 being the content is at the bottom of the scrollwindow. Using _cursor in combination with onScrollUpdate() could be useful to scroll other objects, trigger animations, or run any other actionscript. |
