I have created a custom toolbar which I want to use uniformly across all the views of my app.
PROBLEM: When a ListView item is selected and a detail view loaded, I get the default back button bar and my custom toolbar, as shown above.
How can I merge both bars and have a single bar?
回答1:
Based on your earlier question, I assume you are using an Ext.navigation.View to host your section and vacancy lists.
Instead of creating your own toolbar you could customize the navigationbar of the navigation view. You get access to it by navigationview.getNavigationBar(); A navigationbar is nothing but an Ext.TitleBar, so you can add components by navigationbar.add();
