WorkingInteractiveMode Property

Gets the ImageViewerInteractiveMode that the viewer control is currently using to process input events.

Syntax

JavaScript

get_workingInteractiveMode();
Object.defineProperty('workingInteractiveMode');

Property Value

Type	Description
ImageViewerInteractiveMode	The ImageViewerInteractiveMode that the viewer control is currently using to process input events.

Remarks

ImageViewer will hook to the ImageViewerInteractiveMode.WorkStarted and ImageViewerInteractiveMode.WorkCompleted of the interactive modes set in SetMouseInteractiveMode, MouseWheelInteractiveMode, PinchInteractiveMode or TouchInteractiveMode. When work starts or completes, the WorkingInteractiveModeChanged event fires and the value of WorkingInteractiveMode updates accordingly. Use WorkingInteractiveMode to perform any custom action required by your application.

Example

Start with the ImageViewer example, remove all the code inside the example function (search for the "// TODO: add example code here" comment) and insert the following code:

Open the HTML page in your browser. Now when you click the Example button, the label will be updated as you drag/zoom or use the magnify glass.

JavaScript

example: function SiteLibrary_DefaultPage$example(viewer) {
   // Pan Zoom interactive mode is set in other parts of this demo

   // Hook to WorkingInteractiveMode of the viewer
   viewer.add_workingInteractiveModeChanged
   var exampleLabel = document.getElementById("exampleLabel");
   var content;

   // This will be used by mouse and touch, so delcare it here once
   var zoomPan = new lt.Controls.ImageViewerPanZoomInteractiveMode();

   // Check if the browser supports mouse
   if(lt.LTHelper.supportsMouse) {
      // Zoom pan with left button
      viewer.setMouseInteractiveMode(lt.Controls.MouseButton.left, zoomPan);

      // Magnify glass with right button
      var magnifyGlass = new lt.Controls.ImageViewerMagnifyGlassInteractiveMode();
      viewer.setMouseInteractiveMode(lt.Controls.MouseButton.right, magnifyGlass);

      content = "Left button and drag to pan, left button with control and drag to zoom, right button use the magnify glass";
   } else {
      // Touch device, set zoom pan only
      viewer.set_touchInteractiveMode(zoomPan);
      content = "Touch and drag to pan, pinch to zoom";
   }

   exampleLabel.textContent = content;

   // Hook to the WorkingInteractiveModeChanged event
   viewer.add_workingInteractiveModeChanged(function(sender, e) {
      // Get the current working interactive mode
      var interactiveMode = viewer.get_workingInteractiveMode();
      if(interactiveMode != null) {
         exampleLabel.textContent = content + " - " + interactiveMode.get_name() + " is working";
      }
      else {
         exampleLabel.textContent = content + " - finished working";
      }
   });
},
