Question

I want to implement some kind of taskbar in my ExtJS4.1 application which contains buttons for all floating components like window. If window is created, a button to minimize/maximize should appear in the taskbar.

So, is there a central event which tells me that a (floating) component has been created or has been shown?

Answer 1

I haven’t tested this, but Ext.ComponentManager has a public property called ‘all’ which is a collection of all components. You could add an ‘add’ listener the same way that onAvailable() does.

Ext.ComponentManager.all.on('add', function(map, key, item) {
    // Check if item is a Window and do whatever
});
