|
||
<p>The <a class="link" href="GtkAccessible.html" title="GtkAccessible"><span class="type">GtkAccessible</span></a> class is the base class for accessible
|
||
implementations for <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> subclasses. It is a thin
|
||
wrapper around <a href="/usr/share/gtk-doc/html/atk/AtkObject.html#AtkObject-struct"><span class="type">AtkObject</span></a>, which adds facilities for associating
|
||
a widget with its accessible object.</p>
|
||
<p>An accessible implementation for a third-party widget should
|
||
derive from <a class="link" href="GtkAccessible.html" title="GtkAccessible"><span class="type">GtkAccessible</span></a> and implement the suitable interfaces
|
||
from ATK, such as <a href="/usr/share/gtk-doc/html/atk/AtkText.html#AtkText-struct"><span class="type">AtkText</span></a> or <a href="/usr/share/gtk-doc/html/atk/AtkSelection.html#AtkSelection-struct"><span class="type">AtkSelection</span></a>. To establish
|
||
the connection between the widget class and its corresponding
|
||
acccessible implementation, override the get_accessible vfunc
|
||
in <a class="link" href="GtkWidget.html#GtkWidgetClass" title="struct GtkWidgetClass"><span class="type">GtkWidgetClass</span></a>.</p>
