Required methods

fn connect_apply_tag<F: Fn(&Self, &TextTag, &mut TextIter, &mut TextIter) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::apply-tag signal is emitted to apply a tag to a range of text in a TextBuffer. Applying actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them).

See also: TextBufferExt::apply_tag, TextBufferExt::insert_with_tags, TextBufferExt::insert_range.

tag

the applied tag

start

the start of the range the tag is applied to

end

the end of the range the tag is applied to

fn connect_delete_range<F: Fn(&Self, &mut TextIter, &mut TextIter) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::delete-range signal is emitted to delete a range from a TextBuffer.

Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them). The default signal handler revalidates the start and end iters to both point to the location where text was deleted. Handlers which run after the default handler (see g_signal_connect_after) do not have access to the deleted text.

See also: TextBufferExt::delete.

start

the start of the range to be deleted

end

the end of the range to be deleted

fn connect_insert_child_anchor<F: Fn(&Self, &mut TextIter, &TextChildAnchor) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::insert-child-anchor signal is emitted to insert a TextChildAnchor in a TextBuffer. Insertion actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the location iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted anchor.

See also: TextBufferExt::insert_child_anchor.

location

position to insert anchor in textbuffer

anchor

the TextChildAnchor to be inserted

fn connect_insert_pixbuf<F: Fn(&Self, &mut TextIter, &Pixbuf) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::insert-pixbuf signal is emitted to insert a gdk_pixbuf::Pixbuf in a TextBuffer. Insertion actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the location iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted pixbuf.

See also: TextBufferExt::insert_pixbuf.

location

position to insert pixbuf in textbuffer

pixbuf

the gdk_pixbuf::Pixbuf to be inserted

fn connect_insert_text<F: Fn(&Self, &mut TextIter, &str) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::insert-text signal is emitted to insert text in a TextBuffer. Insertion actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the location iter (or has to revalidate it). The default signal handler revalidates it to point to the end of the inserted text.

See also: TextBufferExt::insert, TextBufferExt::insert_range.

location

position to insert text in textbuffer

text

the UTF-8 text to be inserted

len

length of the inserted text in bytes

fn connect_remove_tag<F: Fn(&Self, &TextTag, &mut TextIter, &mut TextIter) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::remove-tag signal is emitted to remove all occurrences of tag from a range of text in a TextBuffer. Removal actually occurs in the default handler.

Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them).

See also: TextBufferExt::remove_tag.

tag

the tag to be removed

start

the start of the range the tag is removed from

end

the end of the range the tag is removed from
