I am using the vbox layout.
I would like to make my components 'fill out' to the sides when I add them. I use the 'align' attribute with the value 'stretch' :
layout: {
type: 'vbox',
align: 'stretch'
},
..which works fine, but I would like this align/stretch behaviour to happen on just certain components. For example in the diagram below :

I would like to stretch out the text field, but have the button normal size.
Is this possible with vbox or hbox?
