Question

Is there a way to set the Welcome Tab with a property of closable: false? We have customized the welcome html which contains a menu and don't want the users to be able to close the tab.

Answer

Below is an example of the launchapp method in the Hook.js that changes the welcome tab to not be closable.

            launchapp : function(app){
                if (!Ext.isEmpty(app.welcome)){
                    var welcome = Ext.ComponentQuery.query('[welcome]')[0];
                    if (!Ext.isEmpty(welcome) && !Ext.isEmpty(welcome.tab)){
                        welcome.tab.setClosable(false);
                    }
                }
            }
