    Default Unanswered: Activate a Sencha Touch tab from a custom JS function

    I have a Cordova project on iOS and I want to switch to a specific tab following an event 'X'.


    Assuming event 'X' just occurred, my objective C makes the following call to run a JS function `openNotificationTab()` like so:


    Code:
    NSString *goToNotification = [NSString stringWithFormat:@"openNotificationTab()"];
        [viewController.webView stringByEvaluatingJavaScriptFromString:goToNotification];
    The `openNotificationTab()` function resides in filename.js and I verified it is within scope and accessible by testing with an `alert()`.


    Now the definition for my js function is as follows:


    Code:
    function openNotificationTab(){
            Ext.Viewport.setActiveItem({
            xtype: 'notificationtabview'
        	});
        }
    The problem is that this function opens the correct panel, but overlays it on top of everything else. So the entire tab menu is no longer visibile and thus inaccessible.


    I also tried



    Code:
    "Ext.Viewport.setActiveItem(1)" and  "Ext.Viewport.setActiveItem('notificationtabview')"
    but neither does anything. Thanks for your help.

    You're doing it to the viewport, so it will make things full screen or floating.

    You need to add the tab to the tabpanel itself, and tell the tab panel to set that child as the active item.

    So something like this?

    Code:
    Ext.Viewport.down("tabpanel").setActiveItem(tab-index)
