WorkingInteractiveMode Property (ImageViewer)

Summary

The ImageViewerInteractiveMode that is currently processing the input events (working).

Syntax

C++

public virtual ImageViewerInteractiveMode WorkingInteractiveMode { get; }

Public Overridable ReadOnly Property WorkingInteractiveMode() As ImageViewerInteractiveMode 
   Get

public:  
   virtual property ImageViewerInteractiveMode^ WorkingInteractiveMode 
   { 
      ImageViewerInteractiveMode^ get() 
   }

Property Value

The ImageViewerInteractiveMode that is currently processing the input events (working).

Remarks

ImageViewer will hook to the ImageViewerInteractiveMode.WorkStarted and ImageViewerInteractiveMode.WorkCompleted of the interactive modes set in InteractiveModes. When work starts or completes, the PropertyChanged event fires with "WorkingInteractiveMode" as the property name and the value of WorkingInteractiveMode updates accordingly. Use WorkingInteractiveMode to perform any custom action required by your application.

For devices that support mouse pointers, the cursor will change to the value of ImageViewerInteractiveMode.WorkingCursor when the interactive mode is working.

For more information, refer to Image Viewer Interactive Modes.

using Leadtools; 
using Leadtools.Controls; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
using LeadtoolsExamples.Common; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
 
if (_imageViewer.WorkingInteractiveMode != null) 
{ 
   Cursor savedCursor = _imageViewer.WorkingInteractiveMode.WorkingCursor; // save 
   _imageViewer.WorkingInteractiveMode.WorkOnBounds = true; 
   _imageViewer.WorkingInteractiveMode.WorkingCursor = Cursors.WaitCursor; 
   _imageViewer.WorkingInteractiveMode.Start(_imageViewer); 
 
   _imageViewer.WorkingInteractiveMode.WorkCompleted += (sender, e) => 
   { 
      // reset working cursor to saved cursor 
      _imageViewer.WorkingInteractiveMode.WorkingCursor = savedCursor; 
   }; 
}

If Not _imageViewer.WorkingInteractiveMode Is Nothing Then 
   Dim savedCursor As Cursor = _imageViewer.WorkingInteractiveMode.WorkingCursor ' save 
   _imageViewer.WorkingInteractiveMode.WorkOnBounds = True 
   _imageViewer.WorkingInteractiveMode.WorkingCursor = Cursors.WaitCursor 
   _imageViewer.WorkingInteractiveMode.Start(_imageViewer) 
 
   AddHandler _imageViewer.WorkingInteractiveMode.WorkCompleted, 
      Sub(sender, e) 
         ' reset working cursor to saved cursor
