TextTagTableProtocol

public protocol TextTagTableProtocol : ObjectProtocol, BuildableProtocol

You may wish to begin by reading the text widget conceptual overview which gives an overview of all the objects and data types related to the text widget and how they work together.

GtkTextTagTables as GtkBuildable

The GtkTextTagTable implementation of the GtkBuildable interface supports adding tags by specifying “tag” as the “type” attribute of a <child> element.

An example of a UI definition fragment specifying tags:

<object class="GtkTextTagTable">
 <child type="tag">
   <object class="GtkTextTag"/>
 </child>
</object>

The TextTagTableProtocol protocol exposes the methods and properties of an underlying GtkTextTagTable instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see TextTagTable. Alternatively, use TextTagTableRef as a lighweight, unowned reference if you already have an instance you just want to use.

TextTagTable Class: TextTagTableProtocol extension (methods and fields)

  • add(tag:) Extension method

    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.

    Declaration

    Swift

    @inlinable
func add<TextTagT>(tag: TextTagT) -> Bool where TextTagT : TextTagProtocol
    Show on GitHub
  • foreach(func:data:) Extension method

    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).

    Declaration

    Swift

    @inlinable
func foreach(func: @escaping GtkTextTagTableForeach, data: gpointer! = nil)
    Show on GitHub
  • getSize() Extension method

    Returns the size of the table (number of tags)

    Declaration

    Swift

    @inlinable
func getSize() -> Int
    Show on GitHub
  • lookup(name:) Extension method

    Look up a named tag.

    Declaration

    Swift

    @inlinable

    Show on GitHub
  • remove(tag:) Extension method

    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.

    Declaration

    Swift

    @inlinable
func remove<TextTagT>(tag: TextTagT) where TextTagT : TextTagProtocol
    Show on GitHub
  • size Extension method
