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).

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

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

) -> SignalHandlerId
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
.

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

) -> SignalHandlerId
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
.

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.

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

f: F
) -> SignalHandlerId
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).
