DocumentChanged Event

In This Topic

All GoDocument.GoDocument.Changed events get re-raised through this event, for the convenience of writing event handlers on the document's view.

Syntax

[Category("GoView")]
[Description("A GoDocument.Changed event occurred (a GoChangedEventHandler)")]
public event GoChangedEventHandler DocumentChanged

Event Data

The event handler receives an argument of type GoChangedEventArgs containing data related to this event. The following GoChangedEventArgs properties provide information specific to this event.

Property	Description
Document	Gets or sets the GoDocument that raised the Changed event described by this `EventArgs`.
GoObject	Gets the Object as a GoObject.
Hint	Gets or sets the general category of document Changed event.
IsBeforeChanging	Gets or sets whether this event args/undoable edit was created by a document Changed event that represents a call to GoDocument.RaiseChanging or by a call to GoDocument.RaiseChanged.
NewInt	Gets or sets the new integer value information for a change.
NewRect	Gets or sets the new float, PositionF, SizeF, or RectangleF value information for a change.
NewValue	Gets or sets the new arbitrary object value information for a change, including boolean values.
Object	Gets or sets the object that was changed by the document Changed event.
OldInt	Gets or sets the previous or old integer value information for a change.
OldRect	Gets or sets the previous or old float, PositionF, SizeF, or RectangleF value information for a change.
OldValue	Gets or sets the previous or old arbitrary object value information for a change, including boolean values.
PresentationName	Gets the user-visible string description of this undoable edit.
SubHint	Gets or sets the more detailed kind of document Changed event, depending on the particular Hint value.

Remarks

Because the GoChangedEventArgs that are passed on through this event are actually raised by GoDocument.RaiseChanged and distributed by GoDocument.OnChanged, there is no GoView.RaiseDocumentChanged method as would be conventional. As with all events, it is more efficient to override OnDocumentChanged on GoView or GoDocument.OnChanged on GoDocument than it is to register delegates as event handlers on this event.
