Methods

ArrangeOverride(Size)

Calls Arrange on all the "visible" child items. "Visible" items are in the SortedItemMeasuresList.

ComputeBySlicing(List<HeatMapItemMeasure>)

Slices the items based on orientation.

Declaration

protected void ComputeBySlicing(List<HeatMapItemMeasure> items)

Parameters

Type	Name	Description
System.Collections.Generic.List<HeatMapItemMeasure>	items	The HeatMapItemMeasure items

ComputeItemBounds()

Override this method to compute the item bounds. Update AvailableArea as you allocate space between the children

Declaration

protected virtual void ComputeItemBounds()

ComputeNextPosition(Orientation, ref Double, ref Double, Double, Double)

Increments x or y based on the orientation.

Declaration

protected virtual void ComputeNextPosition(Orientation orientation, ref double xPos, ref double yPos, double width, double height)

Parameters

Type	Name	Description
System.Windows.Controls.Orientation	orientation	The orientation.
System.Double	xPos	The X position.
System.Double	yPos	The Y position.
System.Double	width	The width value
System.Double	height	The height value

GetOrientation()

Could be used for slice and dice type layouts to determine the orientation to use for children layout.

Declaration

protected virtual Orientation GetOrientation()

Returns

Type	Description
System.Windows.Controls.Orientation	The orientation

GetRectangle(Orientation, HeatMapItemMeasure, Double, Double, Double, Double)

Returns the rect for a child based on the orientation.

Declaration

protected virtual Rect GetRectangle(Orientation orientation, HeatMapItemMeasure item, double x, double y, double width, double height)

Parameters

Type	Name	Description
System.Windows.Controls.Orientation	orientation	The orientation

MeasureOverride(Size)

calculates the bounds for the items (this information will be stored in the SortedItemMeasuresList). Calls Measure on all the "visible" items.

Declaration

protected override Size MeasureOverride(Size constraint)

Parameters

Type	Name	Description
System.Windows.Size	constraint	The constraint within which to layout the items.

Returns

Type	Description
