ImageViewerInteractiveMode | The ImageViewerInteractiveMode that the viewer control is currently using to process input events. |
ImageViewer will hook to the ImageViewerInteractiveMode.WorkStarted and ImageViewerInteractiveMode.WorkCompleted of the interactive modes set in SetMouseInteractiveMode, MouseWheelInteractiveMode or TouchInteractiveMode. When work starts or completes, the WorkingInteractiveModeChanged event fires and the value of WorkingInteractiveMode updates accordingly. You can use WorkingInteractiveMode to perform any custom action required by your application.
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.
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 Leadtools.Controls.ImageViewerPanZoomInteractiveMode(); // Check if the browser supports mouse if(Leadtools.LTHelper.supportsMouse) { // Zoom pan with left button viewer.setMouseInteractiveMode(Leadtools.Controls.MouseButton.left, zoomPan); // Magnify glass with right button var magnifyGlass = new Leadtools.Controls.ImageViewerMagnifyGlassInteractiveMode(); viewer.setMouseInteractiveMode(Leadtools.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"; } }); },
