TargetImageViewer Property

Summary

Current target image viewer for this drop operation.

Syntax

C++/CLI

public ImageViewer TargetImageViewer { get; }

public:  
   property ImageViewer^ TargetImageViewer 
   { 
      ImageViewer^ get() 
   }

Property Value

The current target image viewer for this drop operation.

Remarks

This changes as the user drags on the application if more than one image viewer exists. It can be null if the object is not currently over an image viewer object and the same value as SourceImageViewer if the item is being dragged over the same viewer (if supported).

Example

using Leadtools; 
using Leadtools.Controls; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
 
public void ImageViewerDragInteractiveModeExample() 
{ 
   _imageViewer.ItemDragDrop += (sender, e) => 
   { 
      _imageViewer.InteractiveModes.BeginUpdate(); 
      e.Effect = DragDropEffects.Copy | DragDropEffects.Move | DragDropEffects.Link; 
      Debug.WriteLine("Format: {0}, Location: {1}, NativeEvent: {2}, Operation: {3}, SourceImageViewer: {4}, SourceItem: {5}, TargetImageViewer: {6}, TargetItem: {7}",  
         e.Format, e.Location, e.NativeEvent, e.Operation, e.SourceImageViewer, e.SourceItem, e.TargetImageViewer, e.TargetItem); 
      _imageViewer.InteractiveModes.EndUpdate(); 
      e.Abort = true; 
   }; 
   _imageViewer.InteractiveModes.BeginUpdate(); 
   ImageViewerDragInteractiveMode dragMode = new ImageViewerDragInteractiveMode(); 
   dragMode.Format = RasterImage.RasterImageDataFormat; 
   dragMode.TargetImageViewerMode = ImageViewerDragTargetMode.All; 
   dragMode.AllowedEffects = DragDropEffects.Copy | DragDropEffects.Move | DragDropEffects.Link; 
   _imageViewer.InteractiveModes.Add(dragMode); 
   _imageViewer.InteractiveModes.EndUpdate(); 
}
