ArrangeOverride(Size)

When overridden in a derived class, positions child elements and determines a size for a FrameworkElement derived class.

protected override Size ArrangeOverride(Size finalSize)

Parameters

finalSize Size

The final area within the parent that this element should use to arrange itself and its children.

Returns

Size

The actual size used.

GetBounds() 

public Rect GetBounds()

Returns

Rect

GetPanCenterToOffset(Point) 

public Point GetPanCenterToOffset(Point ptCenter)

Parameters

ptCenter Point

Returns

Point

GetPanZoomToViewScale(Rect, double, double, bool) 

public double GetPanZoomToViewScale(Rect rc, double pixelMarginX = 2, double pixelMaringY = 2, bool zoomIn = true)

Parameters

rc Rect
pixelMarginX double
pixelMaringY double
zoomIn bool

Returns

double

public Tuple<double, Point> GetTargetCoord(Rect rc, double pixelMarginX = 2, double pixelMaringY = 2, bool zoomIn = true)

Parameters

rc Rect
pixelMarginX double
pixelMaringY double
zoomIn bool

Returns

Tuple<double, Point>

GetVisualChild(int)

Overrides GetVisualChild(int), and returns a child at the specified index from a collection of child elements.

protected override Visual GetVisualChild(int index)

Parameters

index int

The zero-based index of the requested child element in the collection.

Returns

Visual

The requested child element. This should not return null; if the provided index is out of range, an exception is thrown.

InitCoord() 

public void InitCoord()

IsFitRect(Rect) 

public bool IsFitRect(Rect rect)

Parameters

rect Rect

Returns

bool

MeasureOverride(Size)

When overridden in a derived class, measures the size in layout required for child elements and determines a size for the FrameworkElement-derived class.

protected override Size MeasureOverride(Size availableSize)

Parameters

availableSize Size

The available size that this element can give to child elements. Infinity can be specified as a value to indicate that the element will size to whatever content is available.

Returns

Size

The size that this element determines it needs during layout, based on its calculations of child element sizes.
