Detailed Description

A class that provides streaming functionality in a scrolling view.

View Template Specification

The 'placeholder' property may be applied to contents of the view template in order to prevent their instantiation. Since the items of CYIListView are dynamically populated at run-time, they can be configured using the view template, or by configuring placeholders. The placeholder properties can be retreived from the list using GetItemProperties() with the CYIViewTemplate name for the placeholder's layout. The preview tool will make use of these placeholders in the CYIListView's preview.

Layout

A layout must be assigned to a list view before it can be used, as the layout defines the ordering of items within the list view. If a layout is not specified when the list view is initialized, an instance of CYIColumnLayout is assigned automatically.

The initial size of streamable items within a list view is set through the associated adapter.

The layout configuration object for the streamable items can also be configured through the associated adapter. By default, for view-specific adapters, the layout configuration for the streamable items is read from the view's template and the placeholder layers in the list.

Limitations

If an item is streamed in that is smaller than its initial size (as declared in the associated adapter), it may cause more items to get streamed in on the next frame. This can cause visual glitches where items appear in the visible region after a few frames. To avoid this, ensure that the initial size of the item is the minimum possible size for that item.
If an item is streamed in that is smaller or larger than its initial size (as declared in the associated adapter), it may cause the current scroll position to get offset. This typically only happens when scrolling 'back' towards the start of the list view.

Member Function Documentation

◆ ApplyMeasurements()

virtual void CYIListView::ApplyMeasurements ( )

overrideprotectedvirtual

Applies the measured sizes of this node's children.

Note: Typically, if ApplyMeasurements is overridden then Measure must also be overridden.; Measurements should be applied before calculating position for layout.

Warning: Subclasses that override this function must ensure that the ApplyMeasurements function of ALL children of this scene node is called.

Note: Subclasses that override this function should make use of the GetCurrentLayoutDirtyFlag() function (rather than GetLayoutDirtyFlag() ).

Reimplemented from CYIScrollingView.

◆ ChildMovedInVisibleRegion()

virtual CYIAbstractTimeline* CYIListView::GetCascadeTimelineFor	(	TimelineType	type,
		CYISceneView *	pView
	)

overrideprotectedvirtual

Returns the cascade timeline of type type for view pView. When type is CYIScrollingView::TimelineType::In, the timeline with marker name 'CascadeIn' is returned. When type is CYIScrollingView::TimelineType::Out, the timeline with marker name 'CascadeOut' is returned. This function returns nullptr if the relevant timeline could not be located in pView.

Reimplemented from CYIScrollingView.

◆ GetItemIndex()

size_t CYIListView::GetItemIndex ( CYISceneNode * pStreamedItem ) const

Returns the index of the streamed-in item pStreamedItem. If pStreamedItem is not a node that's currently streamed in by this list, std::numeric_limits<size_t>::max() is returned.

Note: pStreamedItem must be a pointer to the root of the view, that is to say it must be the pointer that was returned from the adapter.

◆ GetItemProperties()

IYIPropertiesSource* CYIListView::GetItemProperties ( const CYIString & viewTemplateName ) const

Returns a IYIPropertiesSource for the CYIViewTemplate named viewTemplateName or null if there is no IYIPropertiesSource for viewTemplateName.

Reimplemented from CYIScrollingView.

Reimplemented in CYIPageIndicatorView, and CYIScrollingTextView.

◆ IsInVisibleRegion()

bool CYIListView::IsInVisibleRegion ( size_t index ) const

Returns true if streamable item with index index is within the bounds of this view, defined by its size.

See also: IsInVisibleRegion(const CYISceneNode*) const

Reimplemented from CYIStreamer.

◆ OnStreamedIn()

virtual void CYIListView::OnStreamedIn	(	size_t	index,
		CYISceneNode *	pStreamedItem
	)

overrideprotectedvirtual

A function called when the item at index index is streamed in. The streamed node (as provided by the associated adapter) is provided as pStreamedItem. This function is called after the item has been attached to the scene tree. Subclasses can override this function to perform post-streaming logic.

Note: In some streamer implementations, the position of the streamed items is not set until later in the frame (e.g. after the layout pass). This function being called is only an indication that a new node has been attached to the scene tree.

Reimplemented from CYIStreamer.

◆ OnStreamedOut()

virtual void CYIListView::OnStreamedOut	(	size_t	index,
		CYISceneNode *	pStreamedItem
	)

overrideprotectedvirtual

A function called when the item at index index is streamed out. The streamed node (as provided by the associated adapter) is provided as pStreamedItem. This function is called before the item has been detached from the scene tree. Subclasses can override this function to perform post-streaming logic.

Reimplemented from CYIStreamer.

◆ ParseProperties()

virtual void CYIListView::ParseProperties ( )

overrideprotectedvirtual

The properties outlined in the table at the top are parsed and applied here.

Reimplemented from CYIScrollingView.

◆ RequestFocusOnItem()

bool CYIListView::RequestFocusOnItem	(	size_t	index,
		CYIFocus::Direction	direction = `CYIFocus::Direction::Forward`,
		CYIFocus::FocusRootRule	focusRootRule = `CYIFocus::FocusRootRule::DescendantsUpdateContext`,
		const CYIAABB &	previousFocusRect = `CYIAABB()`
	)

See also: CYIStreamer::RequestFocusOnItem()

◆ RevealItem()

virtual void CYIListView::RevealItem	(	size_t	index,
		uint32_t	duration,
		CYITimeInterpolator *	pInterpolator = `nullptr`
	)

virtual

Reveals the streamable item at index index with an animation of duration duration.

See also: CYIScrollingView::Reveal

◆ SetAdapter()

void CYIListView::SetAdapter ( std::unique_ptr< CYINodeAdapter > pAdapter )

See also: CYIStreamer::SetAdapter()

◆ SetItemProperties()

void CYIListView::SetItemProperties	(	const CYIString &	viewTemplateName,
		std::unique_ptr< IYIPropertiesSource >	pProperties
	)

Set the properties for views in this list created with the CYIViewTemplate named viewTemplateName to pProperties. This method is called after the list is created with the properties of each placeholder in the list. These properties will be given to the CYINodeAdapter when the adapter is set on this list.

Note: This method overwrites any properties previously set.

See also: GetItemProperties; CYINodeAdapter::SetProperties; CYIViewTemplate::GetName; CYIStreamer::SetAdapter

◆ SetStreamingRegionFactor()

void CYIListView::SetStreamingRegionFactor ( float factor )

Sets the factor used to calculate the streaming region to factor. This factor is used along with the visible region of the list to calculate that region in which items would be streamed in. For example, a value of 2.0f would indicate that the streaming region should be 50% larger than the visible region on each side. A value of 1.0f indicates that the streaming region should be exactly equal to the visible region.

The streaming region factor defaults to 2.0f.

Note: Values smaller than 1.0f are not supported. If this function is called with a value smaller than 1.0f, a value of 1.0f is used instead.

◆ UpdateHorizontalPagingStrategyImpl()

virtual void CYIListView::UpdateHorizontalPagingStrategyImpl ( )

overrideprotectedvirtual

Updates the information required by the horizontal paging strategy, such as scroll region width, and scroll position. Subclasses should override if they have visibility into the new information included in a subclass of CYIScrollingView::PagingStrategy.

Reimplemented from CYIScrollingView.

◆ UpdateStreamedStateOfAllItems()

void CYIListView::UpdateStreamedStateOfAllItems ( )

protected

◆ UpdateVerticalPagingStrategyImpl()

virtual void CYIListView::UpdateVerticalPagingStrategyImpl ( )

overrideprotectedvirtual

Updates the information required by the vertical paging strategy, such as scroll region width, and scroll position. Subclasses should override if they have visibility into the new information included in a subclass of CYIScrollingView::PagingStrategy.

Reimplemented from CYIScrollingView.

◆ WorldBoundingBoxUpdated()

virtual void CYIListView::WorldBoundingBoxUpdated ( )

overrideprotectedvirtual

Called by Update() when the world bounding box update process is complete. Subclasses may overload this function to do post-processing.

Warning: The dirty flag will be cleared prior to calling this function to allow new dirty state to be recorded from this function. If querying information about the dirty state of the node, use GetPreviousDirtyFlag().; Overrides must call the base class implementation.

See also: Update(); OnWorldBoundingBoxUpdated()

Reimplemented from CYIScrollingView.
