Description

A gtk.TextTagTable object holds a set of gtk.TextTag objects for use with a gtk.TextBuffer. Usually a gtk.TextTagTable is created automatically when a gtk.TextBuffer is created but a standalone gtk.TextTagTable can be created using the gtk.TextTagTable() constructor. A gtk.TextTagTable can be passed as an argument to the gtk.TextBuffer() constructor to associate an existing gtk.TextTagTable rather than creating a new one. This is useful when several textbuffers need to use the same texttags.

Constructor

    gtk.TextTagTable()

Returns :

a new gtk.TextTagTable

Creates a new gtk.TextTagTable. The table contains no tags by default.

Methods

gtk.TextTagTable.add

    def add(tag)

tag :

a gtk.TextTag

The add() method adds a texttag to the texttagtable. The texttag is assigned the highest priority in the texttagtable. A ValueError exception is raised if tag is in a texttag table already, or has the same name as another texttag in the texttagtable.

gtk.TextTagTable.remove

    def remove(tag)

tag :

a gtk.TextTag

The remove() method removes a texttag from the texttagtable.

gtk.TextTagTable.lookup

    def lookup(name)

name :

the name of a texttag

Returns :

The texttag, or None if none by that name is in the texttagtable.

The lookup() method looks in the texttagtable for a gtk.TextTag with the name specified by name and returns it if found. This method returns None if name does not identify a gtk.TextTag in the texttagtable.

gtk.TextTagTable.foreach

    def foreach(func, data=None)

func :

a function to call on each texttag

data :

user data to pass to func or None

Note

This method is available in PyGTK 2.4 and above.

The foreach() method calls the function specified by func on each texttag in the text tag table passing the user data specified by data. The signature of func is:

  def func(texttag, user_data):

where texttag is a gtk.TextTag in the text tag table and user_data is data. Note that the table may not be modified while iterating over it (you can't add/remove tags).

gtk.TextTagTable.get_size

    def get_size()

Returns :

the number of texttags in the texttagtable

The get_size() method returns the size of the texttagtable (number of texttags).

Signals

The "tag-added" gtk.TextTagTable Signal

    def callback(texttagtable, texttag, user_param1, ...)

texttagtable :

the texttagtable that received the signal

texttag :

a gtk.TextTag

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "tag-added" signal is emitted when the gtk.TextTag specified by texttag is added to texttagtable.

The "tag-changed" gtk.TextTagTable Signal

    def callback(texttagtable, texttag, size_changed, user_param1, ...)

texttagtable :

the texttagtable that received the signal

texttag :

a gtk.TextTag

size_changed :

if True a texttag property has changed that may affect the size of the text enclosed by the texttag

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "tag-changed" signal is emitted when a property of the gtk.TextTag specified by texttag is changed. If size_changed is True the text enclosed by texttag will change size.

The "tag-removed" gtk.TextTagTable Signal

    def callback(texttagtable, texttag, user_param1, ...)

texttagtable :

the texttagtable that received the signal

texttag :

a gtk.TextTag

user_param1 :

the first user parameter (if any) specified with the connect() method

... :

additional user parameters (if any)

The "tag-removed" signal is emitted when the gtk.TextTag specified by texttag is removed from texttagtable
