A TextChildAnchor is a spot in the buffer where child widgets can be “anchored” (inserted inline, as if they were characters). The anchor can have multiple widgets anchored, to allow for multiple views.


Exported types

class GObject o => IsTextChildAnchor o Source #

Type class for types which can be safely cast to TextChildAnchor, for instance with toTextChildAnchor.

toTextChildAnchor :: (MonadIO m, IsTextChildAnchor o) => o -> m TextChildAnchor Source #

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



textChildAnchorGetDeleted Source #


:: (HasCallStack, MonadIO m, IsTextChildAnchor a) 
=> a

anchor: a TextChildAnchor

-> m Bool

Returns: True if the child anchor has been deleted from its buffer

Determines whether a child anchor has been deleted from the buffer. Keep in mind that the child anchor will be unreferenced when removed from the buffer, so you need to hold your own reference (with objectRef) if you plan to use this function — otherwise all deleted child anchors will also be finalized.


textChildAnchorGetWidgets Source #


:: (HasCallStack, MonadIO m, IsTextChildAnchor a) 
=> a

anchor: a TextChildAnchor

-> m [Widget]

Returns: list of widgets anchored at anchor

Gets a list of all widgets anchored at this child anchor. The returned list should be freed with g_list_free().


textChildAnchorNew Source #


:: (HasCallStack, MonadIO m) 
=> m TextChildAnchor

Returns: a new TextChildAnchor

Creates a new TextChildAnchor. Usually you would then insert it into a TextBuffer with textBufferInsertChildAnchor. To perform the creation and insertion in one step, use the convenience function textBufferCreateChildAnchor.
