scroll bar selectable

I have a canvas with a scrollbar and I would like to disable the scrollbar in some way that keeps the thumb visible, but not selectable. I just want to let the user know that there is more information below, but I do not want to let him use the scroll to move down(this will be done with the movement of the arrows). 开发者_开发问答I tried using the properties enabled but it does not work.

Any ideas???

Thanks.

Canvas has verticalScrollBarStyleName used for scrollbar skinning. This is name of CSS style which will be assigned to vertical Scrollbar, which in turn has following styles: thumbUpSkin, thumbOverSkin, thumbDownSkin. You need some custom class for thumb with mouseEnabled=false. Set these styles to this thumb class name.
