GI.Gio.Objects.MenuLinkIter
Description
MenuLinkIter is an opaque structure type. You must access it using
the functions below.
Since: 2.32
Synopsis
- newtype MenuLinkIter = MenuLinkIter (ManagedPtr MenuLinkIter)
- class (GObject o, IsDescendantOf MenuLinkIter o) => IsMenuLinkIter o
- toMenuLinkIter :: (MonadIO m, IsMenuLinkIter o) => o -> m MenuLinkIter
- menuLinkIterGetName :: (HasCallStack, MonadIO m, IsMenuLinkIter a) => a -> m Text
- menuLinkIterGetNext :: (HasCallStack, MonadIO m, IsMenuLinkIter a) => a -> m (Bool, Text, MenuModel)
- menuLinkIterGetValue :: (HasCallStack, MonadIO m, IsMenuLinkIter a) => a -> m MenuModel
- menuLinkIterNext :: (HasCallStack, MonadIO m, IsMenuLinkIter a) => a -> m Bool

toMenuLinkIter :: (MonadIO m, IsMenuLinkIter o) => o -> m MenuLinkIter Source #
Cast to MenuLinkIter, for types for which this is known to be safe. For general casts, use castTo.

getName
Arguments
| :: (HasCallStack, MonadIO m, IsMenuLinkIter a) | |
| => a |
|
| -> m Text | Returns: the type of the link |
Gets the name of the link at the current iterator position.
The iterator is not advanced.
Since: 2.32
getNext
Arguments
| :: (HasCallStack, MonadIO m, IsMenuLinkIter a) | |
| => a |
|
| -> m (Bool, Text, MenuModel) | Returns: |
This function combines menuLinkIterNext with
menuLinkIterGetName and menuLinkIterGetValue.
First the iterator is advanced to the next (possibly first) link.
If that fails, then False is returned and there are no other effects.
If successful, outLink and value are set to the name and MenuModel
of the link that has just been advanced to. At this point,
menuLinkIterGetName and menuLinkIterGetValue will return the
same values again.
The value returned in outLink remains valid for as long as the iterator
remains at the current position. The value returned in value must
be unreffed using objectUnref when it is no longer in use.
