class TextTagTable(**properties: Any)

Superclasses: Object

Implemented Interfaces: Buildable

Constructors:

TextTagTable(**properties)
new() -> Gtk.TextTagTable

Constructors

class TextTagTable

classmethod new() → TextTagTable

Creates a new GtkTextTagTable.

The table contains no tags by default.

Methods

class TextTagTable

add(tag: 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.

Parameters:

tag – a GtkTextTag

foreach(func: Callable[[...], None], *data: Any) → None

Calls func on each tag in table, with user data data.

Note that the table may not be modified while iterating over it (you can’t add/remove tags).

Parameters:

• func – a function to call on each tag

• data – user data

get_size() → int

Returns the size of the table (number of tags)

lookup(name: str) → TextTag | None

Look up a named tag.

Parameters:

name – name of a tag

remove(tag: TextTag) → None

Remove a tag from the table.

If a GtkTextBuffer has table 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.

Parameters:

tag – a GtkTextTag

Signals

class TextTagTable.signals

tag_added(tag: TextTag) → None

Emitted every time a new tag is added in the GtkTextTagTable.

Parameters:

tag – the added tag.

tag_changed(tag: TextTag, size_changed: bool) → None

Emitted every time a tag in the GtkTextTagTable changes.

Parameters:

• tag – the changed tag.

• size_changed – whether the change affects the GtkTextView layout.

tag_removed(tag: TextTag) → None

Emitted every time a tag is removed from the GtkTextTagTable.

The tag is still valid by the time the signal is emitted, but it is not associated with a tag table any more.

Parameters:

tag – the removed tag.
