Hi Dominik, why not have a display interface like this?
interface Display {
void toggleVisible(boolean toggle);
}
If you need the presenter to toggle specific widgets on the display create
an enum:
interface Display {
enum WidgetType {
BUTTON,
TEXTBOX
};
void toggleVisible(boolean toggle, WidgetType type);
}
