Protected Methods

Method	Description
ArrangeOverride ( Size finalSize ) : Size	This is the 2nd pass of the layout process, where child controls are being arranged within the panel.
MeasureOverride ( Size availableSize ) : Size	This is the 1st pass of the layout process. Here, the Extent's size is being determined.

OnVisualChildrenChanged ( DependencyObject visualAdded, DependencyObject visualRemoved ) : void

Private Methods

Method	Description
CalculateNewScrollOffset ( double dblViewport_Left, double dblViewport_Right, double dblChild_Left, double dblChild_Right ) : double	Calculates the HorizontalOffset for a given child-control, based on a desired value.
GetChildRectangle ( UIElement uieChild ) : Rect	Returns the rectangle that defines the outer bounds of a child control.
GetIntersectionRectangle ( UIElement uieChild ) : Rect	Returns a Rectangle that contains the intersection between the ScrollViewer's and the passed child control's boundaries, that is, the portion of the child control which is currently visibile within the ScrollViewer's Viewport.
GetScrollViewerRectangle ( ) : Rect	Returns the currently rendered rectangle that makes up the Viewport.
NotifyPropertyChanged ( String strPropertyName ) : void	Called from within this class whenever subscribers (i.e. bindings) are to be notified of a property-change
RemoveOpacityMask ( UIElement uieChild ) : void	Will remove the OpacityMask for all child controls.
RemoveOpacityMasks ( ) : void	Will remove the OpacityMask for all child controls.
ScrollOwner_Loaded ( object sender, RoutedEventArgs e ) : void	Fired when the ScrollViewer is initially loaded/displayed. Required in order to initially setup the childrens' OpacityMasks.
ScrollableTabPanel_SizeChanged ( object sender, System.Windows.SizeChangedEventArgs e ) : void
UpdateMembers ( Size szExtent, Size szViewportSize ) : void	Compares the present sizes (Extent/Viewport) against the local values and updates them, if required.
UpdateOpacityMask ( UIElement uieChild ) : void	Takes the given child control and checks as to whether the control is completely visible (in the Viewport). If not (i.e. if it's only partially visible), an OpacityMask will be applied so that it fades out into nothingness.
UpdateOpacityMasks ( ) : void	Will check all child controls and set their OpacityMasks.
daScrollAnimation_Completed ( object sender, EventArgs e ) : void	Fired when the scroll-animation has finished its work, that is, at the point in time when the ScrollViewerer has reached its final scroll-position resp. offset, which is when the childrens' OpacityMasks can be updated.
getLeftEdge ( UIElement uieChild ) : double	Returns the left position of the requested child (in Viewport-coordinates).
