Popovers Deep Dive

Normally Views cannot draw outside of their Viewport. Options for influencing content outside of the Viewport include:

1. Modifying the Border behavior
2. Modifying the Margin behavior
3. Using Popover

Popovers are useful for scenarios such as menus, autocomplete popups, and drop-down combo boxes.

A Popover is any View that meets these characteristics"

• Implements the IPopover interface
• Is Focusable (CetFocus = true)
• Is Transparent (ViewportSettings = ViewportSettings.Transparent | ViewportSettings.TransparentMouse
• Sets Visible = false when it receives Application.QuitKey

PopoverMenu provides a sophisticated implementation.
