Scrolling

The container control automatically provides horizontal or vertical scroll bars, or both, whenever the container window's work area is not large enough to display all of the container items.

If all container items are visible in the work area, the scroll bars are either removed or disabled, depending on the view and how the items are positioned, as follows:

If container items are displayed in the icon or tree view, and one or more items are not visible in the work area, a horizontal scroll bar, vertical scroll bar, or both, are provided, depending on the position of the items outside of the work area. If container items are positioned to the right or left of the work area, a horizontal scroll bar is provided; if container items are positioned below or above the work area, a vertical scroll bar is provided.
Scroll bars are not provided if all the container items are visible in the work area. Scroll bars are removed from the container window if either of the following occurs:
- Container items positioned outside the work area are moved into the work area.
- The size of the container window is increased so that container items formerly not visible become visible.
