GI.Gtk.Objects.CustomFilter
Description
GtkCustomFilter determines whether to include items with a callback.
Synopsis
- newtype CustomFilter = CustomFilter (ManagedPtr CustomFilter)
- class (GObject o, IsDescendantOf CustomFilter o) => IsCustomFilter o
- toCustomFilter :: (MonadIO m, IsCustomFilter o) => o -> m CustomFilter
- customFilterNew :: (HasCallStack, MonadIO m) => Maybe CustomFilterFunc -> m CustomFilter
- customFilterSetFilterFunc :: (HasCallStack, MonadIO m, IsCustomFilter a) => a -> Maybe CustomFilterFunc -> m ()

class (GObject o, IsDescendantOf CustomFilter o) => IsCustomFilter o Source #
Type class for types which can be safely cast to CustomFilter, for instance with toCustomFilter.

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

Arguments
| :: (HasCallStack, MonadIO m) | |
| => Maybe CustomFilterFunc |
|
| -> m CustomFilter | Returns: a new |
Creates a new filter using the given matchFunc to filter
items.
If matchFunc is Nothing, the filter matches all items.
If the filter func changes its filtering behavior,
filterChanged needs to be called.
setFilterFunc
customFilterSetFilterFunc Source #
Arguments
| :: (HasCallStack, MonadIO m, IsCustomFilter a) | |
| => a |
|
| -> Maybe CustomFilterFunc |
|
| -> m () |
Sets the function used for filtering items.
If matchFunc is Nothing, the filter matches all items.
If the filter func changes its filtering behavior,
filterChanged needs to be called.
If a previous function was set, its userDestroy will be
called now.
