Indicates whether an application's floating windows are currently visible.
pascal Boolean AreFloatingWindowsVisible (void);
When your application receives a suspend event, it must hide any visible floating windows. When your application receives a resume event, it must make its floating windows visible again. If your application needs to check which visibility state its floating windows are in, it may call the AreFloatingWindowsVisible function.
You should call the function InitFloatingWindows prior to calling AreFloatingWindowsVisible .
The AreFloatingWindowsVisible function operates only upon windows created with the kFloatingWindowClass constant; see Window Class Constants for more details on this constant.
