58 * SECTION:view
59 * @Short_description: Subclass of #CtkTextView
60 * @Title: CtkSourceView
61 * @See_also: #CtkTextView, #CtkSourceBuffer
62 *
63 * #CtkSourceView is the main class of the CtkSourceView library.
64 * Use a #CtkSourceBuffer to display text with a #CtkSourceView.
65 *
66 * This class provides:
67 * - Show the line numbers;
68 * - Show a right margin;
69 * - Highlight the current line;
70 * - Indentation settings;
71 * - Configuration for the Home and End keyboard keys;
72 * - Configure and show line marks;
73 * - And a few other things.
74 *
75 * An easy way to test all these features is to use the test-widget mini-program
76 * provided in the CtkSourceView repository, in the tests/ directory.
77 *
78 * # CtkSourceView as CtkBuildable
79 *
80 * The CtkSourceView implementation of the #CtkBuildable interface exposes the
81 * #CtkSourceView:completion object with the internal-child "completion".
82 *
83 * An example of a UI definition fragment with CtkSourceView:
84 * |[
85 * <object class="CtkSourceView" id="source_view">
86 * <property name="tab_width">4</property>
87 * <property name="auto_indent">True</property>
88 * <child internal-child="completion">
89 * <object class="CtkSourceCompletion">
90 * <property name="select_on_show">False</property>
91 * </object>
92 * </child>
93 * </object>
94 * ]|
95 *
96 * # Changing the Font
97 *
98 * Ctk CSS provides the best way to change the font for a #CtkSourceView in a
99 * manner that allows for components like #CtkSourceMap to scale the desired
100 * font.
101 *
102 * |[
103 * CtkCssProvider *provider = ctk_css_provider_new ();
104 * ctk_css_provider_load_from_data (provider,
105 * "textview { font-family: Monospace; font-size: 8pt; }",
106 * -1,
107 * NULL);
108 * ctk_style_context_add_provider (ctk_widget_get_style_context (view),
109 * CTK_STYLE_PROVIDER (provider),
110 * CTK_STYLE_PROVIDER_PRIORITY_APPLICATION);
111 * g_object_unref (provider);
112 * ]|
113 *
114 * If you need to adjust the font or size of font within a portion of the
115 * document only, you should use a #CtkTextTag with the #CtkTextTag:family or
116 * #CtkTextTag:scale set so that the font size may be scaled relative to
117 * the default font set in CSS.
