The #style methods are not called during execution of live callbacks.
Even if they were, their corresponding values would not be used,
elements. Processing them, i.e. download the stylesheets and apply
the styles would be quite a challenge.
There might be a way though, to achieve what you are looking for.
The code below is written using the email editor, therefore untested
1) Add new methods to your component
html attributes id: 'live-styles'.
html tag: 'style' do: self liveStyle.
^ whatever styles need to be changed by live callbacks
2) Call the first method from your rendering method, must be at the end.
live-update the style element.
4) Pray for the browser to update the styles when the style element is
live-updated. Some browsers may, some other may not.
