How do you set initial focus in a layout?

Question

rebol []

view [ 
    f: field "" 
    button "focus" on-action [
        focus f
    ]
    when [load] on-action [focus f] 
]

Using the focus button sets the focus correctly but I'd like the focus to set when the panel appears. I'd have thought the load trigger should do this but it doesn't.

Answer 1

The correct trigger to use is the 'enter trigger

when [enter] on-action [focus f]
