I want a Spec application to add an additional item to the System Window Menu. Is this possible? So far I have missed how it might be done. This System Window Menu seems to come from... SystemWindow>>offerWindowMenu | aMenu | aMenu := self buildWindowMenu. model ifNotNil: [model addModelItemsToWindowMenu: aMenu]. aMenu popUpEvent: self currentEvent in: self world where #buildWindowMenu produces a standard menu from pragmas and custom model specific menu items can be added with #addModelItemsToWindowMenu:. In the case of PharoLauncher, 'model' is a MorphicWindowAdapter for which #addModelItemsToWindowMenu: is a null-method inherited from Object. So maybe 'model' needs to be a different class somehow? Alternatively, I see that SpecWindow inherits from SystemWindow, so maybe #buildWindowMenu can be overridden to add menu items from subclasses of ComposableModel ? cheers -ben
