4 There is now a user manual which can be read using yelp and can be found under
5 'development'. Please refer to this documentation for up-to-date information.
8 NOTE: This is only a draft version. Don't make major changes to your
9 documentation until we've agreed on all this.
12 GTK+ Reference Documentation Style Guide
13 ========================================
15 This file describes the way the GTK+ reference documentation should be written,
16 so that we produce consistent documentation.
18 We will also designate one or two of the template files as 'model' templates,
19 i.e. they are to be taken as the 'correct' way to write the documentation:
21 GtkFontSelectionDialog - contains example code and descriptions of enums.
22 GtkMisc - contains description of fields in a widget struct.
28 Use American spelling rather than British, i.e. color rather than colour,
29 organize rather than organise etc.
31 End all descriptions of functions & parameters with a period '.'.
37 The organization of the sections is determined by the glib-sections.txt,
38 gdk-sections.txt and gtk-sections.txt files.
40 Group related functions/macros/enums etc. and place a "<SUBSECTION>" tag
41 (on its own line) between groups. This results in a blank line in the synopsis
42 between the groups, which makes it a bit easier to read.
44 Order the groups sections by placing the most important/commonly-used
45 functions/macros etc. first. For pairs of accessor functions place them
46 together with the 'get' function first and then the 'set' function.
48 Private functions etc. should be placed at the end of the "<SECTION>",
49 after a "<SUBSECTION Private>" line. They will not appear in the HTML output
50 and they do not have to be documented (they will disappear form the template
51 files the next time 'make templates' is run).
53 Enumerations should appear after the first function which uses them.
59 For widgets, start the main description with -
61 <!-- ##### SECTION Long_Description ##### -->
63 The #GtkFontSelectionDialog widget ...
66 If you want to include subsections in the main description, to conform to
67 DocBook SGML you must have 0 or more leading paragraphs (or possibly other
68 DocBook tags - see the DTD), then 1 or more <refsect2> subsections, with
71 <!-- ##### SECTION Long_Description ##### -->
73 Introduction to the section....
76 <title>First Subsection</title>
78 This is the first subsection.
82 <title>Second Subsection</title>
84 This is the second subsection.
89 Functions & Macro Descriptions
90 ==============================
92 Start the description with a phrase like this:
93 'Looks up a key in a GHashTable'.
94 i.e. assume that 'This function' (or 'This macro') precedes it.
100 For object-oriented code, denote the object parameter with 'a',
101 e.g. 'a #GHashTable'.
103 Use 'the' for the rest of the parameters.
109 Some widget structs have fields which are useful to the developer, since
110 there are currently no accessor functions to retrieve the particular field.
112 These fields should be documented as follows:
114 -----------------------------------------------------------------------
115 <!-- ##### STRUCT GtkFixedChild ##### -->
117 The #GtkFixedChild-struct struct contains the following fields.
118 (These fields should be considered read-only. They should never be set by
122 @widget: the child #GtkWidget.
123 @x: the horizontal position of the widget within the #GtkFixed
125 @y: the vertical position of the widget within the #GtkFixed
127 -----------------------------------------------------------------------
130 If a widget struct is completely private, use this:
132 -----------------------------------------------------------------------
133 <!-- ##### STRUCT GtkFontSelectionDialog ##### -->
135 The #GtkFontSelectionDialog-struct struct contains private data only, and
136 should be accessed using the functions below.
138 -----------------------------------------------------------------------
140 Note that the links to the widget names go to the top of the page,
141 e.g. links to #GtkAccelLabel result in a link to the GtkAccelLabel page.
142 If you want to link to the widget struct, you must append '-struct',
143 e.g. #GtkAccelLabel-struct
145 Whether a particular field in a structure is output in the
146 documentation is determined by adding /*< public >*/ and
147 /*< private >*/ comments into the header files. For instance,
148 GtkEditable looks like:
150 -----------------------------------------------------------------------
158 guint selection_start_pos;
159 guint selection_end_pos;
160 guint has_selection : 1;
168 gchar *clipboard_text;
170 -----------------------------------------------------------------------
172 You should add these as you go along. Please send these changes
173 in along with your patches for the reference docs. Widget structures
174 are by default all private, other structures are by default all public.
180 A lot of the enumerations in GTK+ are currently placed in the "Standard
181 Enumerations" section. However, some of these are specific to a particular
182 widget and so should be moved to the widget's section and documented there.
184 The enumeration values should be documented as follows:
186 -----------------------------------------------------------------------
187 <!-- ##### ENUM GtkFontFilterType ##### -->
189 A set of bit flags used to specify the filter being set
190 when calling gtk_font_selection_dialog_set_filter() or
191 gtk_font_selection_set_filter().
194 @GTK_FONT_FILTER_BASE: the base filter, which can't be changed by the user.
195 @GTK_FONT_FILTER_USER: the user filter, which can be changed from within the 'Filter' page
196 of the #GtkFontSelection widget.
197 -----------------------------------------------------------------------
203 To link to related widgets/pages, use a <variablelist> like below.
204 If there aren't any related pages, simply leave the See_Also section as it is,
205 and it will not be output.
206 Note that ancestors of widgets may automatically be added here, so
207 don't add them yourself.
209 -----------------------------------------------------------------------
210 <!-- ##### SECTION See_Also ##### -->
215 <term>#GtkFontSelection</term>
216 <listitem><para>the underlying widget for selecting fonts.</para></listitem>
221 -----------------------------------------------------------------------
224 Including Hypertext Links
225 =========================
227 Use the <ulink> tag to include hypertext links, e.g.
229 Gnome's home page is at <ulink url="www.gnome.org">www.gnome.org</ulink>.
231 Remember that the documentation may be printed, so it is probably best
232 to repeat the URL within the link.
