Field Detail

visibleTop

public int visibleTop

The visible top presents the top edge of the visible rect of the content. If the value is 0 then the item is fully visible from the top; if the value is > 0 then some part of the content is hidden from the top. Consequently if the value is 0 and percentVisibleHeight < 100, then the content is hidden from the bottom edge.

visibleLeft

public int visibleLeft

The visible left presents the left edge of the visible rect of the content. If the value is 0 then the item is fully visible from the left; if the value is > 0 then some part of the content is hidden from the left. Consequently if the value is 0 and percentVisibleWidth < 100, then the content is hidden from the right edge.
