|
||
<p>The <a class="link" href="GtkBin.html" title="GtkBin"><span class="type">GtkBin</span></a> widget is a container with just one child.
|
||
It is not very useful itself, but it is useful for deriving subclasses,
|
||
since it provides common code needed for handling a single child widget.</p>
|
||
<p>Many GTK+ widgets are subclasses of <a class="link" href="GtkBin.html" title="GtkBin"><span class="type">GtkBin</span></a>, including <a class="link" href="GtkWindow.html" title="GtkWindow"><span class="type">GtkWindow</span></a>,
