That is, their type specific implementations are 60 relocatable/unloadable during runtime. 61 </para></listitem> 62 <listitem><para> 63 A collection of fundamental type implementations, such as integers, 64 doubles, enums and structured types, to name a few. 65 </para></listitem> 66 <listitem><para> 67 A sample fundamental type implementation to base object hierarchies 68 upon - the GObject fundamental type. 69 </para></listitem> 70 <listitem><para> 71 A signal system that allows very flexible user customization of 72 virtual/overridable object methods and can serve as a powerful 73 notification mechanism. 74 </para></listitem> 75 <listitem><para> 76 An extensible parameter/value system, supporting all the provided 77 fundamental types that can be used to generically handle object 78 properties or otherwise parameterized types. 79 </para></listitem> 80 </itemizedlist> 81 </para> 82 </preface> 83 84 <part label="I"> 85 <title>Concepts</title> 86 87 &tutorial-Intro; 88 &tutorial-GType; 89 &tutorial-GObject; 90 &tutorial-GSignal; 91 </part> 92 <reference label="II"> 93 <title>API Reference</title> 94 95 &gobject-GType; 96 &gobject-GTypePlugin; 97 &gobject-GTypeModule; 98 &gobject-The-Base-Object-Type; 99 &gobject-Enumeration-and-Flag-Types; 100 &gobject-Boxed-Types; 101 &gobject-Generic-values; 102 &gobject-param-value-types; 103 &gobject-Varargs-Value-Collection; 104 &gobject-GParamSpec; 105 &gobject-Signals; 106 &gobject-Closures; 107 &gobject-Value-Arrays; 108 109 </reference> 110 <reference label="III"> 111 <title>Tools Reference</title> 112 113 &glib-mkenums; 114 &glib-genmarshal; 115 &gobject-query; 116 </reference> 117 <part label="IV"> 118 <title>Tutorial</title> 119 120 &tutorial-HowTo; 121 </part> 122 <part label="V"> 123 <title>Related Tools</title> 124 125 &tutorial-Tools; 126 </part> 127 128 <index> 129 <title>Index</title> 130 </index> 131 <index role="deprecated"> 132 <title>Index of deprecated symbols</title> 133 </index> 134 <index role="2.2"> 135 <title>Index of new symbols in 2.2</title> 136 </index> 137 <index role="2.4"> 138 <title>Index of new symbols in 2.4</title> 139 </index> 140 <index role="2.6"> 141 <title>Index of new symbols in 2.6</title> 142 </index> 143 <index role="2.8"> 144 <title>Index of new symbols in 2.8</title> 145 </index> 146 <index role="2.10"> 147 <title>Index of new symbols in 2.10</title> 148 </index> 149 <index role="2.12"> 150 <title>Index of new symbols in 2.12</title> 151 </index> 152 <index role="2.14"> 153 <title>Index of new symbols in 2.14</title> 154 </index> 155 <index role="2.18"> 156 <title>Index of new symbols in 2.18</title> 157 </index> 158 159</book> 160
