WG: How to display a working actionButtonView into aGraphicsContext?

Hello forum.
Hello forum. I have to upgrade an already existing custom list view (subclass: View). Until now each list item included only simple visual components, like text labels and images. But no interactive components, like action buttons, etc. Now my task is to display a working action button in a list item, if it is selected. I don't like to reinvent the list component, so I've tried to display a ActionButtonView into the GraphicsContext. But all my approach failed. Until now, my best and also simplest try was: buttonView := myBuilder policy actionButtonClass new. buttonView label: anImage. buttonView displayOn: aGraphicsContext at: aPoint. The button is displayed in the list. But I am not able to make it working. I cannot assign the desired action. Also the fly-by-help does not work. Assigning the proper controller seem not to help. buttonView controller: buttonView defaultController. Can someone give me an advice please? And in general: Is this a good or a bad approach? And how to get the default "actionButtonClass" without using the builder? I've tried to get the information by the DefaultLookPolicy. Without success. Thank you for your answers.
