AnnContainer Class

Represents an Annotation container.

Object Model

Syntax

C#
Visual Basic
Objective-C
Java
C++

public class AnnContainer : System.Windows.Controls.Canvas, IAnnContainer, System.ComponentModel.ISupportInitialize, System.Windows.IFrameworkInputElement, System.Windows.IInputElement, System.Windows.Markup.IAddChild, System.Windows.Markup.IQueryAmbient, System.Windows.Media.Animation.IAnimatable

'Declaration
 
Public Class AnnContainer 
   Inherits System.Windows.Controls.Canvas
   Implements IAnnContainer, System.ComponentModel.ISupportInitialize, System.Windows.IFrameworkInputElement, System.Windows.IInputElement, System.Windows.Markup.IAddChild, System.Windows.Markup.IQueryAmbient, System.Windows.Media.Animation.IAnimatable

'Usage
 
Dim instance As AnnContainer

public ref class AnnContainer : public System.Windows.Controls.Canvas, IAnnContainer, System.ComponentModel.ISupportInitialize, System.Windows.IFrameworkInputElement, System.Windows.IInputElement, System.Windows.Markup.IAddChild, System.Windows.Markup.IQueryAmbient, System.Windows.Media.Animation.IAnimatable

Remarks

The annotation container is a Panel that holds annotation objects. The container is responsible for maintaining these objects as well as rendering them.

Example

For XAML example, refer to AnnGroupObject.

This example creates a new AnnContainer object, links it to a Leadtools.Windows.Controls.ImageViewer object, adds a few objects and then adds the container on as a content of the viewer. Moving the mouse over an object displays the object type in the title bar.
