SizeChangedInfo Constructor

Initializes a new instance of the SizeChangedInfo class.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

public SizeChangedInfo(
	UIElement element,
	Size previousSize,
	bool widthChanged,
	bool heightChanged


Type: System.Windows.UIElement

The element where the size is being changed.

Type: System.Windows.Size

The previous size, before the change.

Type: System.Boolean

true if the Width component of the size changed.

Type: System.Boolean

true if the Height component of the size changed.

For the two Boolean parameters, note that you should report these as true only if the changes in the value are significant to rendering, or should interpret the values as such if reading existing values. Minor changes in the size values are possible due to precision side-effects, particularly when mathematical functions are applied to the double values.
