GtkTextTag: GtkTextTag

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

A tag that can be applied to text in a GtkTextBuffer

Methods and Functions

gtkTextTagNew(name = NULL)
gtkTextTagGetPriority(object)
gtkTextTagSetPriority(object, priority)
gtkTextTagEvent(object, event.object, event, iter)
gtkTextAttributesNew()
gtkTextAttributesCopy(object)
gtkTextAttributesCopyValues(object, dest)
gtkTextTag(name = NULL)

Detailed Description

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. gtkTextBufferCreateTag is the best way to create tags. See gtk-demo for numerous examples.

The "invisible" property was not implemented for GTK+ 2.0. It is working (with minor issues) since 2.8.

Structures

GtkTextAttributes

Using GtkTextAttributes directly should rarely be necessary. It's primarily useful with gtkTextIterGetAttributes. As with most GTK+ structs, the fields in this struct should only be read, never modified directly.

Convenient Construction

gtkTextTag is the equivalent of gtkTextTagNew.

Enums and Flags

GtkWrapMode

Describes a type of line wrapping.

none

do not wrap lines; just make the text area wider

char

wrap text, breaking lines anywhere the cursor can appear (between characters, usually - if you want to be technical, between graphemes, see pangoGetLogAttrs)

word

wrap text, breaking lines in between words

word_char

wrap text, breaking lines in between words, or if that is not enough, also between graphemes.

Signals

event(tag, object, event, iter, user.data)

The ::event signal is emitted when an event occurs on a region of the buffer marked with this tag.

tag

the GtkTextTag on which the signal is emitted

object

the object the event was fired from (typically a GtkTextView)

event

the event which triggered the signal

iter

a GtkTextIter pointing at the location the event occured

user.data

user data set when the signal handler was connected.

Returns: [logical] TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.

Properties

accumulative-margin [logical : Read / Write]

Whether the margins accumulate or override each other.

When set to TRUE the margins of this tag are added to the margins of any other non-accumulative margins present. When set to FALSE the margins override one another (the default). Default value: FALSE Since 2.12

Whether the background color fills the entire line height or only the height of the tagged characters. Default value: FALSE

background-full-height-set [logical : Read / Write]

Whether this tag affects background height. Default value: FALSE

background-gdk [GdkColor : * : Read / Write]

Background color as a (possibly unallocated) GdkColor.

Whether this tag affects the font family. Default value: FALSE

font [character : * : Read / Write]

Font description as string, e.g. \"Sans Italic 12\".

Note that the initial value of this property depends on the internals of PangoFontDescription. Default value: NULL

font-desc [PangoFontDescription : * : Read / Write]

Font description as a PangoFontDescription struct.

foreground [character : * : Write]

Foreground color as a string. Default value: NULL

foreground-gdk [GdkColor : * : Read / Write]

Foreground color as a (possibly unallocated) GdkColor.

foreground-set [logical : Read / Write]

Whether this tag affects the foreground color. Default value: FALSE

Bitmap to use as a mask when drawing the text foreground.

foreground-stipple-set [logical : Read / Write]

Whether this tag affects the foreground stipple. Default value: FALSE

indent [integer : Read / Write]

Amount to indent the paragraph, in pixels. Default value: 0

indent-set [logical : Read / Write]

Whether this tag affects indentation. Default value: FALSE
