Description
GtkCustomSorter is a GtkSorter implementation that sorts via a callback
function.
Synopsis
- newtype CustomSorter = CustomSorter (ManagedPtr CustomSorter)
- class (GObject o, IsDescendantOf CustomSorter o) => IsCustomSorter o
- toCustomSorter :: (MonadIO m, IsCustomSorter o) => o -> m CustomSorter
- customSorterNew :: (HasCallStack, MonadIO m) => Maybe CompareDataFunc -> m CustomSorter
- customSorterSetSortFunc :: (HasCallStack, MonadIO m, IsCustomSorter a) => a -> Maybe CompareDataFunc -> m ()

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

Arguments
| :: (HasCallStack, MonadIO m) | |
| => Maybe CompareDataFunc |
|
| -> m CustomSorter | Returns: a new |
Creates a new GtkSorter that works by calling
sortFunc to compare items.
If sortFunc is Nothing, all items are considered equal.

customSorterSetSortFunc Source #
Arguments
| :: (HasCallStack, MonadIO m, IsCustomSorter a) | |
| => a |
|
| -> Maybe CompareDataFunc |
|
| -> m () |
Sets (or unsets) the function used for sorting items.
If sortFunc is Nothing, all items are considered equal.
If the sort func changes its sorting behavior,
sorterChanged needs to be called.
If a previous function was set, its userDestroy will be
called now.
