AnnTextRollupObject Class

Summary

This class provides support for creating and managing text rollup annotation objects.

Remarks

The text rollup annotation object extends AnnNoteObject by adding an IsExpanded property. When this property is set to false, the text rollup object looks and behaves like a normal note. When IsExpanded is set to false, the text rollup object will shrink to show only one line of text. This saves space on the container surface. For more information, refer to Using Text in WPF Annotation Objects. For more information about the text rollup annotation object refer to WPF AnnTextRollupObject. For more information about the automated text rollup annotation object, refer to WPF Annotation Objects - Automated Features.

Example

C#
VB
using Leadtools.Windows.Controls; 
using Leadtools.Windows.Annotations; 
using Leadtools.Demos; 
using Leadtools.Help; 
 
private void AnnTextRollupObject_AnnTextRollupObject(ImageViewer viewer, AnnContainer container) 
{ 
   AnnTextRollupObject textRollup = new AnnTextRollupObject(); 
   textRollup.Text = "My TextRollup object"; 
 
   textRollup.FontSize = 10; 
   textRollup.TextEdgeMargin = 0.0; 
   textRollup.ShadowBorderWidth = 6.0; 
   textRollup.TextHorizontalAlignment = AnnTextAlignment.Center; 
   textRollup.TextVerticalAlignment = AnnTextAlignment.Center; 
 
   textRollup.FontFamilyName = "Arial"; 
   textRollup.FontStyle = AnnFontStyle.Normal; 
   textRollup.Rect = new Rect(100, 200, 400, 600); 
 
   container.Children.Add(textRollup); 
 
   textRollup.IsExpanded = false; 
 
   MessageBox.Show("Not expanded"); 
 
   textRollup.IsExpanded = true; 
 
   MessageBox.Show("expanded"); 
}
