OnObservedChanged Method (GoObject)

Called when an observed object has been changed.

Syntax

Visual Basic
C#

'Declaration
 
Protected Overridable Sub OnObservedChanged( _
   ByVal observed As GoObject, _
   ByVal subhint As Integer, _
   ByVal oldI As Integer, _
   ByVal oldVal As Object, _
   ByVal oldRect As RectangleF, _
   ByVal newI As Integer, _
   ByVal newVal As Object, _
   ByVal newRect As RectangleF _
)

protected virtual void OnObservedChanged( 
   GoObject observed,
   int subhint,
   int oldI,
   object oldVal,
   RectangleF oldRect,
   int newI,
   object newVal,
   RectangleF newRect
)

Parameters

observed: The modified object being observed by this object.
subhint: The same as for the Changed method.
oldI: The same as for the Changed method.
oldVal: The same as for the Changed method.
oldRect: The same as for the Changed method.
newI: The same as for the Changed method.
newVal: The same as for the Changed method.
newRect: The same as for the Changed method.

Remarks

Changed calls this method on each of the observing objects that were registered with the observed object by a call to AddObserver. If the observed's SuspendsUpdates property is true, this method will not be called on its observers. Unlike GoDocument.Changed events, this method will be called even when the observed object is not part of a document. By default this method does nothing. Any implementation of this method should be very careful about causing any changes to the observed object.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
