Summary

Occurs when an AnnObject is being edited.

Syntax

Java

Objective-C

WinRT C#

public event EventHandler<AnnEditDesignerEventArgs> Edit

Public Event Edit As EventHandler(Of AnnEditDesignerEventArgs)

public event EventHandler<AnnEditDesignerEventArgs> Edit

-(void) automation:(LTAnnAutomation*) automation editWithArgs:(LTAnnEditDesignerEventArgs*) e;

public void addEditDesignerdListener(AnnEditDesignerListener listener) 
public void removeEditDesignerListener(AnnEditDesignerListener listener)

add_Edit(function(sender, e)) 
remove_Edit(function(sender, e))

Event Data

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

Property	Description
Cancel	Gets or sets a value indicating whether the edit operation should be canceled.
MoveThumbIndex	Gets the index of the thumb (control point) being moved.
Object	Gets the AnnObject that is being edited.
Operation	Gets the type of the current edit operation.
OperationStatus	Gets the status of the current edit operation.

Remarks

When an object is being edited, the automation object will hook the object edit designer's AnnEditDesigner.Edit to this event. Therefore, instead of hooking and unhooking to the various designers edit events, you can simply subscribe to this event once.

Example

This example will show how to track when an object is edited.

Start with the AnnAutomationManager example, remove all the code inside the example function (search for the // TODO: add example code here comment) and insert the following code:

Click the example button. Now whenever you move or resize an object, you will get the message.
