class (GObject o, IsDescendantOf CustomSorter o) => IsCustomSorter o

Type class for types which can be safely cast to CustomSorter, for instance with toCustomSorter.

new

customSorterNew

Arguments

:: (HasCallStack, MonadIO m)

=> Maybe CompareDataFunc

sortFunc: the GCompareDataFunc to use for sorting

-> m CustomSorter

Returns: a new GtkCustomSorter

Creates a new GtkSorter that works by calling sortFunc to compare items.

If sortFunc is Nothing, all items are considered equal.

setSortFunc

customSorterSetSortFunc

Arguments

:: (HasCallStack, MonadIO m, IsCustomSorter a)

=> a

self: a GtkCustomSorter

-> Maybe CompareDataFunc

sortFunc: function to sort items

-> 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.
