1. type AssistantPageFunc_WithClosures = Int32 -> Ptr () -> IO Int32

   gi-gtk4	GI.Gtk.Callbacks

   Type of callback used to calculate the next page in a GtkAssistant. It’s called both for computing the next page when the user presses the “forward” button and for handling the behavior of the “last” button. See assistantSetForwardPageFunc.

2. type C_AssistantPageFunc = Int32 -> Ptr () -> IO Int32

   gi-gtk4	GI.Gtk.Callbacks

   Type for the callback on the (unwrapped) C side.

3. type C_PageSetupDoneFunc = Ptr PageSetup -> Ptr () -> IO ()

   gi-gtk4	GI.Gtk.Callbacks

   Type for the callback on the (unwrapped) C side.

4. drop_closures_AssistantPageFunc :: AssistantPageFunc -> AssistantPageFunc_WithClosures

   gi-gtk4	GI.Gtk.Callbacks

   A simple wrapper that ignores the closure arguments.

5. drop_closures_PageSetupDoneFunc :: PageSetupDoneFunc -> PageSetupDoneFunc_WithClosures

   gi-gtk4	GI.Gtk.Callbacks

   A simple wrapper that ignores the closure arguments.

6. dynamic_AssistantPageFunc :: (HasCallStack, MonadIO m) => FunPtr C_AssistantPageFunc -> Int32 -> Ptr () -> m Int32

   gi-gtk4	GI.Gtk.Callbacks

   Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

7. dynamic_PageSetupDoneFunc :: (HasCallStack, MonadIO m, IsPageSetup a) => FunPtr C_PageSetupDoneFunc -> a -> Ptr () -> m ()

   gi-gtk4	GI.Gtk.Callbacks

   Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

8. genClosure_AssistantPageFunc :: MonadIO m => AssistantPageFunc -> m (GClosure C_AssistantPageFunc)

   gi-gtk4	GI.Gtk.Callbacks

   Wrap the callback into a GClosure.

9. genClosure_PageSetupDoneFunc :: MonadIO m => PageSetupDoneFunc -> m (GClosure C_PageSetupDoneFunc)

   gi-gtk4	GI.Gtk.Callbacks

   Wrap the callback into a GClosure.

10. mk_AssistantPageFunc :: C_AssistantPageFunc -> IO (FunPtr C_AssistantPageFunc)

    gi-gtk4	GI.Gtk.Callbacks

    Generate a function pointer callable from C code, from a C_AssistantPageFunc.
