Description

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.

Synopsis

newtype TextChildAnchor = TextChildAnchor (ManagedPtr TextChildAnchor)
class (GObject o, IsDescendantOf TextChildAnchor o) => IsTextChildAnchor o
toTextChildAnchor :: (MonadIO m, IsTextChildAnchor o) => o -> m TextChildAnchor
noTextChildAnchor :: Maybe TextChildAnchor
textChildAnchorGetDeleted :: (HasCallStack, MonadIO m, IsTextChildAnchor a) => a -> m Bool
textChildAnchorGetWidgets :: (HasCallStack, MonadIO m, IsTextChildAnchor a) => a -> m [Widget]
textChildAnchorNew :: (HasCallStack, MonadIO m) => m TextChildAnchor

class (GObject o, IsDescendantOf TextChildAnchor 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.

noTextChildAnchor :: Maybe TextChildAnchor Source #

A convenience alias for Nothing :: Maybe TextChildAnchor.

Methods

getDeleted

textChildAnchorGetDeleted Source #

Arguments

:: (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.

getWidgets

textChildAnchorGetWidgets Source #

Arguments

:: (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().

new

textChildAnchorNew Source #

Arguments

:: (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.
