Ext JS: What is the difference between an "hbox"/"column" layout and a toolbar?

Question

I wonder whether I should choose an Ext.Panel with an hbox layout or an Ext.Toolbar in order to put some buttons below a comment input field. Both are suitable for holding a set of controls.

Answer 1

It depends on the required functionality- using a hbox leads to further nesting within your view, so a more complex dom (which typically should be avoided), whereas a toolbar can be applied directly to the parent component. Though both may be suitable for holding a set of controls, toolbars are specifically designed to do so, as such they are a more complex object- again, if you require the functionality they provide (styling, methods etc) then using one should be the choice. Its kind of hard to say based on the limited detail provided
