Expand description

Trait containing all TextTagTable methods.

§Implementors

TextTagTable

Provided Methods§

Source

fn add(&self, tag: &impl IsA<TextTag>) -> bool

Add a tag to the table. The tag is assigned the highest priority in the table.

tag must not be in a tag table already, and may not have the same name as an already-added tag.

§tag

a TextTag

§Returns

true on success.

Source

fn foreach<P: FnMut(&TextTag)>(&self, func: P)

Calls func on each tag in self, with user data data. Note that the table may not be modified while iterating over it (you can’t add/remove tags).

§func

a function to call on each tag

Source

fn size(&self) -> i32

Returns the size of the table (number of tags)

§Returns

number of tags in self

Source

fn lookup(&self, name: &str) -> Option<TextTag>

Look up a named tag.

§name

name of a tag

§Returns

The tag, or None if none by that name is in the table.

Source

fn remove(&self, tag: &impl IsA<TextTag>)

Remove a tag from the table. If a TextBuffer has self as its tag table, the tag is removed from the buffer. The table’s reference to the tag is removed, so the tag will end up destroyed if you don’t have a reference to it.

§tag

a TextTag

Source

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

§tag

the added tag.

Source

fn connect_tag_changed<F: Fn(&Self, &TextTag, bool) + 'static>( &self, f: F, ) -> SignalHandlerId

§tag

the changed tag.

§size_changed

whether the change affects the TextView layout.

Source

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

§tag

the removed tag.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
