WorkingInteractiveMode Property

Summary

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

Syntax

C++/CLI

public virtual ImageViewerInteractiveMode WorkingInteractiveMode { 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.

   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; 
      }; 
   } 
}
