GI.Gtk.Interfaces.TreeSortable

The interface for sortable models used by GtkTreeView

GtkTreeSortable is an interface to be implemented by tree models which support sorting. The GtkTreeView uses the methods provided by this interface to sort the model.

Exported types

newtype TreeSortable

Deprecated: (Since version 4.10)There is no replacement for this interface. You should use SortListModel to wrap your list model instead

Memory-managed wrapper type.

Constructors

type ParentTypes TreeSortable

Defined in GI.Gtk.Interfaces.TreeSortable

type ParentTypes TreeSortable = '[TreeModel, Object]

class (GObject o, IsDescendantOf TreeSortable o) => IsTreeSortable o

Type class for types which can be safely cast to TreeSortable, for instance with toTreeSortable.

Instances

(GObject o, IsDescendantOf TreeSortable o) => IsTreeSortable o

toTreeSortable :: (MonadIO m, IsTreeSortable o) => o -> m TreeSortable

Cast to TreeSortable, for types for which this is known to be safe. For general casts, use castTo.

getSortColumnId

treeSortableGetSortColumnId

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> m (Bool, Int32, SortType)

Returns: True if the sort column is not one of the special sort column ids.

Deprecated: (Since version 4.10)

Fills in sortColumnId and order with the current sort column and the order. It returns True unless the sortColumnId is TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.

hasDefaultSortFunc

treeSortableHasDefaultSortFunc

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> m Bool

Returns: True, if the model has a default sort function

Deprecated: (Since version 4.10)

Returns True if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.

setDefaultSortFunc

treeSortableSetDefaultSortFunc

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> TreeIterCompareFunc

sortFunc: The comparison function

-> m ()

Deprecated: (Since version 4.10)

Sets the default comparison function used when sorting to be sortFunc. If the current sort column id of sortable is TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.

If sortFunc is Nothing, then there will be no default comparison function. This means that once the model has been sorted, it can’t go back to the default state. In this case, when the current sort column id of sortable is TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.

setSortColumnId

treeSortableSetSortColumnId

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> Int32

sortColumnId: the sort column id to set

-> SortType

order: The sort order of the column

-> m ()

Deprecated: (Since version 4.10)

Sets the current sort column to be sortColumnId. The sortable will resort itself to reflect this change, after emitting a GtkTreeSortable::sort-column-changed signal. sortColumnId may either be a regular column id, or one of the following special values:

• TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set
• TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur

setSortFunc

treeSortableSetSortFunc

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> Int32

sortColumnId: the sort column id to set the function for

-> TreeIterCompareFunc

sortFunc: The comparison function

-> m ()

Deprecated: (Since version 4.10)

Sets the comparison function used when sorting to be sortFunc. If the current sort column id of sortable is the same as sortColumnId, then the model will sort using this function.

sortColumnChanged

treeSortableSortColumnChanged

Arguments

:: (HasCallStack, MonadIO m, IsTreeSortable a)

=> a

sortable: A GtkTreeSortable

-> m ()

Deprecated: (Since version 4.10)

Emits a GtkTreeSortable::sort-column-changed signal on sortable.

Signals

sortColumnChanged

type TreeSortableSortColumnChangedCallback = IO ()

The sortColumnChanged signal is emitted when the sort column or sort order of sortable is changed. The signal is emitted before the contents of sortable are resorted.

afterTreeSortableSortColumnChanged :: (IsTreeSortable a, MonadIO m) => a -> ((?self :: a) => TreeSortableSortColumnChangedCallback) -> m SignalHandlerId

Connect a signal handler for the sortColumnChanged signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after treeSortable #sortColumnChanged callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onTreeSortableSortColumnChanged :: (IsTreeSortable a, MonadIO m) => a -> ((?self :: a) => TreeSortableSortColumnChangedCallback) -> m SignalHandlerId

Connect a signal handler for the sortColumnChanged signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on treeSortable #sortColumnChanged callback
