Can someone show me an implementation of a custom FlatMenu? I ve been trying for hours to get a custom popup menu, by inheriting from FlatMenu, but it gives me tons and tons of errors every time, most if not all of them, are about unimplemented methods that should be overridden. But idk how to override them, like the Dismiss method. In fact, idk how to implement FlatMenu in a sub class. To more details, I made a post on WxWidgets subreddit.
