Detailed Description

View class.

Library: display

A scroll view contains a pair of scroll bars, allowing the user to scroll the lower-level drawing view contained within the scroll view. IlvScrollView is a possible parent for an IlvView object.

IlvScrollView

To operate properly, this class needs a widget toolkit linked to your application. If you do not want or do not have the associated libraries, refer to the pure Rogue Wave Views implementation, IlvScrolledView.
An IlvScrollView must contain a single child view, which can be bigger than its parent. The IlvScrollView handles all automatic scrolling operations by means of scroll bars located on the right and bottom of the scrolling view. You can manipulate the scroll bars to display new areas of the subview.

Constructor & Destructor Documentation

IlvScrollView::IlvScrollView ( IlvDisplay display,
IlvSystemView  parent,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Constructor.

This constructor creates a view that is a child of the existing system view indicated by parent. This constructor thus handles a non-Rogue Wave Views window object within an IlvScrollView object. This can be any of your system windows, such as those created by other applications.

Parameters
displayThe display instance.
parentThe parent view.
sizeThe dimensions of the view.
visibleSpecifies whether the scroll view object is visible.
IlvScrollView::IlvScrollView ( IlvAbstractView parent,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Constructor.

This constructor initializes a scroll view object that is a child of the parent view. The dimensions of the view are indicated by size. The new scroll view object is not visible if visible has the value IlFalse.

Parameters
parentThe parent view.
sizeThe dimensions of the view.
visibleSpecifies whether the scroll view object is visible.
