AnnContainer Class

Summary

Represents an Annotation container.

Syntax

C#
VB
C++
public class AnnContainer : IAnnContainer, Canvas 
  
Public Class AnnContainer  
   Inherits System.Windows.Controls.Canvas 
   Implements Leadtools.Windows.Annotations.IAnnContainer, System.ComponentModel.ISupportInitialize, System.Windows.IFrameworkInputElement, System.Windows.IInputElement, System.Windows.Markup.IAddChild, System.Windows.Markup.IQueryAmbient, System.Windows.Media.Animation.IAnimatable  
public ref class AnnContainer : public System.Windows.Controls.Canvas, Leadtools.Windows.Annotations.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.
