Reload already initialized viewer to display new study uid

[sylvainb31]

Hi,

I have embedded the viewer in my web app and everything is working fine.

(version used : "library": "@ohif/viewer@4.5.28",)

I use it to see directly the images of a specific study uid. When I first initialize the viewer, everything works fine, displaying the studyuid I have in my url, but I now need to display other study uid and I don't want to reload the web page containing the ohif viewer to do so.

I have my own list of study uids displayed on the left side of the viewer, and by clicking on a studyuid, I want to be able to reload directly the viewer.

Is there a way to do this ?

Maybe a function like window.OHIFViewer.reload() that would keep the initial configuration initialized but display the new studyuid that I have in my url.

Or is there a way to safely destroy the viewer and reinitialize it again ?

Here is the code of my viewer initialization :

<script src="~/lib/ohif/viewer/dist/index.umd.js?release=3.0.0.3"></script>

<script>

    if (affichageOngletImages == "True") {

        var urlForOhifViewer = "/Home/Viewer/viewer/@(Model.ReponseRecuperationDocument.StudyUid.ToString())";
        console.log("urlForOhifViewer = " + urlForOhifViewer);
        history.replaceState(null, null, urlForOhifViewer);

        var containerId = "root";
        var componentRenderedOrUpdatedCallback = function () {
            console.log('OHIF Viewer rendered/updated');

        }
        window.OHIFViewer.installViewer(
            {
                routerBasename: '/Home/Viewer',
                extensions: [], /* https://github.com/OHIF/Viewers/issues/1722 commentaire pour inclure extensions :  https://github.com/OHIF/Viewers/issues/1003#issuecomment-539190501 */
                showStudyList: true,
                filterQueryParam: false,
                maxConcurrentMetadataRequests: 1,
                servers: {
                    dicomWeb: [
                        {
                            name: 'DCM4CHEE',
                            wadoUriRoot: '/api/WadoUriAPI', /* https://dicomcloud.azurewebsites.net/api https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/wado /api/WadoUriAPI  /api/WadoUriAPI/getImageDicom */

                            imageRendering: '@(Model.WadoRsOuWadoUri)', /* wadors / wadouri voir : https://github.com/OHIF/Viewers/issues/1338 et https://github.com/OHIF/Viewers/issues/482 */
                            thumbnailRendering: '@(Model.WadoRsOuWadoUri)', /* wadors / wadouri */
                            enableStudyLazyLoad: true, /* a vérifier l'utilité de la propriété */
                        },
                    ],
                }
            },
            containerId,
            componentRenderedOrUpdatedCallback
        );

    }

</script>

Thanks in advance for your help that would be greatly appreciated :)

Here is what I've tried to do (you can find the result with the error attached) :

Deleting the container holding the viewer, and adding a new div with an other id. Then initializing the viewer again with this new container.

The metadata are loaded and the thumbnail images are loaded but there is a problem loading the main images. There is also the popup to download the image that appears with an error message.

            $("#viewerWrapperDiv").empty();

            $("#viewerWrapperDiv").append("<div id='newidviewer' style='width: 98 %; height: 90 %; '></div>")

            var containerIdNewViewer = "newidviewer";
            var componentRenderedOrUpdatedCallbackNewViewer = function () {
                console.log('OHIF New Viewer rendered/updated');

            }
            window.OHIFViewer.installViewer(
                {
                    routerBasename: '/Home/Viewer',

                componentRenderedOrUpdatedCallbackNewViewer
            );

Hello @sylvainb31, Did you find any workaround on this?

I'm trying to push new configuration to OHIF viewer using installViewer approach but it always picks previous configurations.

Please review the latest code in the master branch. I am confident that this issue has been resolved. If it persists, kindly reopen the issue with updated details.

Try viewer-dev.ohif.org instead of viewer.ohif.org Our viewer.ohif.org is deployed from release branch while viewer-dev.ohif.org is our master branch Read more about branch explanations here https://docs.ohif.org/development/getting-started#developing
