<a name="GtkViewport.description"></a><h2>Description</h2>
<p>
The <a class="link" href="GtkViewport.html" title="GtkViewport"><span class="type">GtkViewport</span></a> widget acts as an adaptor class, implementing
scrollability for child widgets that lack their own scrolling
capabilities. Use <a class="link" href="GtkViewport.html" title="GtkViewport"><span class="type">GtkViewport</span></a> to scroll child widgets such as
<a class="link" href="GtkTable.html" title="GtkTable"><span class="type">GtkTable</span></a>, <a class="link" href="GtkBox.html" title="GtkBox"><span class="type">GtkBox</span></a>, and so on.
</p>
<p>
If a widget has native scrolling abilities, such as <a class="link" href="GtkTextView.html" title="GtkTextView"><span class="type">GtkTextView</span></a>,
<a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> or <span class="type">GtkIconview</span>, it can be added to a <a class="link" href="GtkScrolledWindow.html" title="GtkScrolledWindow"><span class="type">GtkScrolledWindow</span></a>
with <a class="link" href="GtkContainer.html#gtk-container-add" title="gtk_container_add ()"><code class="function">gtk_container_add()</code></a>. If a widget does not, you must first add the
widget to a <a class="link" href="GtkViewport.html" title="GtkViewport"><span class="type">GtkViewport</span></a>, then add the viewport to the scrolled window.
The convenience function <a class="link" href="GtkScrolledWindow.html#gtk-scrolled-window-add-with-viewport" title="gtk_scrolled_window_add_with_viewport ()"><code class="function">gtk_scrolled_window_add_with_viewport()</code></a> does
exactly this, so you can ignore the presence of the viewport.
