6. threadsEnter :: IO ()

   gtk	Graphics.UI.Gtk.General.General

   Acquire the global Gtk lock.

   • During normal operation, this lock is held by the thread from which all interaction with Gtk is performed. When calling mainGUI, the thread will release this global lock before it waits for user interaction. During this time it is, in principle, possible to use a different OS thread (any other Haskell thread that is bound to the Gtk OS thread will be blocked anyway) to interact with Gtk by explicitly acquiring the lock, calling Gtk functions and releasing the lock. However, the Gtk functions that are called from this different thread may not trigger any calls to the OS since this will lead to a crash on Windows (the Win32 API can only be used from a single thread). Since it is very hard to tell which function only interacts on Gtk data structures and which function call actual OS functions, it is best not to use this feature at all. A better way to perform updates in the background is to spawn a Haskell thread and to perform the update to Gtk widgets using postGUIAsync or postGUISync. These will execute their arguments from the main loop, that is, from the OS thread of Gtk, thereby ensuring that any Gtk and OS function can be called.

7. threadsLeave :: IO ()

   gtk	Graphics.UI.Gtk.General.General

   Release the global Gtk lock.

   • The use of this function is not recommended. See threadsEnter.

8. unsafeInitGUIForThreadedRTS :: IO [String]

   gtk	Graphics.UI.Gtk.General.General

   No documentation available.

9. printOptReady :: PrintOperationPreviewClass self => Signal self (PrintContext -> IO ())

   gtk	Graphics.UI.Gtk.Printing.PrintOperation

   The ready signal gets emitted once per preview operation, before the first page is rendered. A handler for this signal can be used for setup tasks.

10. FileChooserErrorAlreadyExists :: FileChooserError

    gtk	Graphics.UI.Gtk.Selectors.FileChooser

    No documentation available.
