Description

Text should be implemented by AtkObjects on behalf of widgets that have text content which is either attributed or otherwise non-trivial. AtkObjects whose text content is simple, unattributed, and very brief may expose that content via atk_object_get_name instead; however if the text is editable, multi-line, typically longer than three or four words, attributed, selectable, or if the object already uses the 'name' ATK property for other information, the Text interface should be used to expose the text content. In the case of editable text content, EditableText (a subtype of the Text interface) should be implemented instead.

Text provides not only traversal facilities and change notification for text content, but also caret tracking and glyph bounding box calculations. Note that the text strings are exposed as UTF-8, and are therefore potentially multi-byte, and caret-to-byte offset mapping makes no assumptions about the character length; also bounding box glyph-to-offset mapping may be complex for languages which use ligatures.

Wrap a TextTextInsertCallback into a C_TextTextInsertCallback.

textRemove

type C_TextTextRemoveCallback = Ptr () -> Int32 -> Int32 -> CString -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type TextTextRemoveCallback Source #

Arguments

= Int32	`arg1`: The position (character offset) of the removal.
-> Int32	`arg2`: The length (in characters) of text removed.
-> Text	`arg3`: The old text removed
-> IO ()

The "text-remove" signal is emitted when a new text is removed. If the signal was not triggered by the user (e.g. typing or pasting text), the "system" detail should be included.

afterTextTextRemove :: (IsText a, MonadIO m) => a -> TextTextRemoveCallback -> m SignalHandlerId Source #

Connect a signal handler for the “text-remove” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after text #textRemove callback

genClosure_TextTextRemove :: MonadIO m => TextTextRemoveCallback -> m (GClosure C_TextTextRemoveCallback) Source #

Wrap the callback into a GClosure.

mk_TextTextRemoveCallback :: C_TextTextRemoveCallback -> IO (FunPtr C_TextTextRemoveCallback) Source #

Generate a function pointer callable from C code, from a C_TextTextRemoveCallback.

noTextTextRemoveCallback :: Maybe TextTextRemoveCallback Source #

A convenience synonym for Nothing :: Maybe TextTextRemoveCallback.

onTextTextRemove :: (IsText a, MonadIO m) => a -> TextTextRemoveCallback -> m SignalHandlerId Source #

Connect a signal handler for the “text-remove” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on text #textRemove callback

wrap_TextTextRemoveCallback :: TextTextRemoveCallback -> C_TextTextRemoveCallback Source #

Wrap a TextTextRemoveCallback into a C_TextTextRemoveCallback.

textSelectionChanged

type C_TextTextSelectionChangedCallback = Ptr () -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type TextTextSelectionChangedCallback = IO () Source #

The "text-selection-changed" signal is emitted when the selected text of an object which implements AtkText changes.

afterTextTextSelectionChanged :: (IsText a, MonadIO m) => a -> TextTextSelectionChangedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “text-selection-changed” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after text #textSelectionChanged callback

genClosure_TextTextSelectionChanged :: MonadIO m => TextTextSelectionChangedCallback -> m (GClosure C_TextTextSelectionChangedCallback) Source #

Wrap the callback into a GClosure.

mk_TextTextSelectionChangedCallback :: C_TextTextSelectionChangedCallback -> IO (FunPtr C_TextTextSelectionChangedCallback) Source #

Generate a function pointer callable from C code, from a C_TextTextSelectionChangedCallback.

noTextTextSelectionChangedCallback :: Maybe TextTextSelectionChangedCallback Source #

A convenience synonym for Nothing :: Maybe TextTextSelectionChangedCallback.

onTextTextSelectionChanged :: (IsText a, MonadIO m) => a -> TextTextSelectionChangedCallback -> m SignalHandlerId Source #

Connect a signal handler for the “text-selection-changed” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on text #textSelectionChanged callback

wrap_TextTextSelectionChangedCallback :: TextTextSelectionChangedCallback -> C_TextTextSelectionChangedCallback Source #

Wrap a TextTextSelectionChangedCallback into a C_TextTextSelectionChangedCallback.
