<h2>Description:</h2> <tt><font color=navy><b>Gtk::ScrolledWindow</b></font></tt> is a <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3ABin.html"><tt><font color=navy><b>Bin</b></font></tt></a></tt> subclass: it's a container that accepts a single child widget. <tt><font color=navy><b>Gtk::ScrolledWindow</b></font></tt> adds scrollbars to the child widget. <P> The scrolled window can work in two ways. Some widgets have native scrolling support; these widgets have <i>slots</i> for <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AAdjustment.html"><tt><font color=navy><b>Adjustment</b></font></tt></a></tt> objects. The scrolled window installs <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AAdjustment.html"><tt><font color=navy><b>Adjustment</b></font></tt></a></tt> objects in the child window's slots using the set_scroll_adjustments_signal, found in the <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AWidget.html"><tt><font color=navy><b>Widget</b></font></tt></a></tt> Class. (This is how it works in GTK+, not sure about GTK--). <P> The second way to use the scrolled window is useful with widgets that lack the set_scroll_adjustments_signal. The <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AViewport.html"><tt><font color=navy><b>Viewport</b></font></tt></a></tt> widget acts as a proxy, implementing scrollability for child widgets that lack their own scrolling capabilities. <P> If a widget has native scrolling abilities, it can be added to the <tt><font color=navy><b>Gtk::ScrolledWindow</b></font></tt> with <a href="Gtk%3A%3AContainer.html#989"><tt><font color=blue><b>add</b></font></tt></a>. If a widget does not, you must first add the widget to a <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AViewport.html"><tt><font color=navy><b>Viewport</b></font></tt></a></tt>, then add the <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AViewport.html"><tt><font color=navy><b>Viewport</b></font></tt></a></tt> to the scrolled window. The convenience function <a href="Gtk%3A%3AScrolledWindow.html#2685"><tt><font color=blue><b>add_with_viewport</b></font></tt></a> does exactly this, so you can ignore the presence of the viewport.<br> <p> <hr noshade> <h2>Function Member Descriptions:</h2> <a name="2685"><font size=+1><b>Gtk::ScrolledWindow::add_with_viewport</b></font></a> - Used to add children without native scrolling capabilities.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt><tt><font color=purple>void</font></tt></tt> <a href="Gtk%3A%3AScrolledWindow.html#2685"><tt><font color=blue><b>add_with_viewport</b></font></tt></a><tt>(<a href="Gtk%3A%3AWidget.html"><tt><font color=navy><b>Widget</b></font></tt></a>& <tt><font color=blue>child</font></tt>)</tt>;<br><blockquote> This is simply a convenience function; it is equivalent to adding the unscrollable child to a viewport, then adding the viewport to the scrolled window. If a child has native scrolling, use <a href="Gtk%3A%3AContainer.html#989"><tt><font color=blue><b>add</b></font></tt></a> instead of this function. <P> The viewport scrolls the child by moving its <tt><tt><font color=navy><b>Gdk::Window</b></font></tt></tt>, and takes the size of the child to be the size of its toplevel <tt><tt><font color=navy><b>Gdk::Window</b></font></tt></tt>. This will be very wrong for most widgets that support native scrolling; for example, if you add a <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3ACList.html"><tt><font color=navy><b>CList</b></font></tt></a></tt> with a viewport, the whole widget will scroll, including the column headings. Thus <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3ACList.html"><tt><font color=navy><b>CList</b></font></tt></a></tt> supports scrolling already, and should not be used with the <tt><a href="Gtk.html"><tt><font color=navy><b>Gtk</b></font></tt></a>::<a href="Gtk%3A%3AViewport.html"><tt><font color=navy><b>Viewport</b></font></tt></a></tt> proxy. <tt><font color=blue>child</font></tt>: Widget you want to scroll.</blockquote> <br><br> <a name="2678"><font size=+1><b>Gtk::ScrolledWindow::get_hadjustment</b></font></a> -
