Class
GtkTextTag
Description [src]
class Gtk.TextTag : GObject.Object
{
GtkTextTagPrivate* priv
}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.
Tags should be in the GtkTextTagTable for a given GtkTextBuffer
before using them with that buffer.
gtk_text_buffer_create_tag() is the best way to create tags.
See “gtk3-demo” for numerous examples.
For each property of GtkTextTag, there is a “set” property, e.g.
“font-set” corresponds to “font”. These “set” properties reflect
whether a property has been set or not.
They are maintained by GTK+ and you should not set them independently.
Constructors
gtk_text_tag_new
Creates a GtkTextTag. Configure the tag using object arguments,
i.e. using g_object_set().
Instance methods
gtk_text_tag_changed
Emits the GtkTextTagTable::tag-changed signal on the GtkTextTagTable where
the tag is included.
since: 3.20
gtk_text_tag_set_priority
Sets the priority of a GtkTextTag. Valid priorities
start at 0 and go to one less than gtk_text_tag_table_get_size().
Each tag in a table has a unique priority; setting the priority
of one tag shifts the priorities of all the other tags in the
table to maintain a unique priority for each tag. Higher priority
tags “win” if two tags both set the same text attribute. When adding
a tag to a tag table, it will be assigned the highest priority in
the table by default; so normally the precedence of a set of tags
is the order in which they were added to the table, or created with
gtk_text_buffer_create_tag(), which adds the tag to the buffer’s table automatically.
Properties
Gtk.TextTag:language
The language this text is in, as an ISO code. Pango can use this as a hint when rendering the text. If not set, an appropriate default will be used.
Gtk.TextTag:paragraph-background-gdk
The paragraph background color as a GdkColor.
deprecated: 3.4 since: 2.8
Gtk.TextTag:strikethrough-rgba
This property modifies the color of strikeouts. If not set, strikeouts will use the forground color.
since: 3.16
Gtk.TextTag:strikethrough-rgba-set
If the GtkTextTag:strikethrough-rgba property has been set.
since: 3.16
Gtk.TextTag:underline-rgba
This property modifies the color of underlines. If not set, underlines will use the forground color.
since: 3.16
Signals
Gtk.TextTag::event
The ::event signal is emitted when an event occurs on a region of the buffer marked with this tag.
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
