A Boolean value that indicates whether the receiver is a floating panel.
- macOS 10.0+
The value of this property is
YES when the receiver is a floating panel,
By default, panels do not float above other windows. It’s appropriate for a panel to float above other windows only if all of the following conditions are true:
It’s small enough not to obscure whatever is behind it.
It’s oriented more to the mouse than to the keyboard—that is, if it doesn’t become the key window or becomes so only when needed.
It needs to remain visible while the user works in the app’s standard windows—for example, if the user must frequently move the pointer back and forth between a standard window and the panel (such as a tool palette), or if the panel gives information relevant to the user’s actions in a standard window.
It hides when the app is deactivated (the default behavior for panels).
