NAME

Prima::Widget::ScrollWidget - scrollable generic document widget

DESCRIPTION

"Prima::Widget::ScrollWidget" is a simple class that declares two pairs of properties, delta and limit for vertical and horizontal axes, which define the extensions of a virtual document. limit is the document dimension, and delta is the current offset.

"Prima::Widget::ScrollWidget" is a descendant of "Prima::Widget::GroupScroller", and as well as its ascendant, provides the same user navigation by two scrollbars. The scrollbars' "partial" and "whole" properties are automatically updated when the document or widget extensions change.

"Prima::Widget::ScrollGroup" provides the capability of hosting other widgets inside, and also scrolling them. Useful for widget group panels that cannot fit in a window
