Some widgets have nativescrolling support; these widgets have "slots" for <AHREF="gtkadjustment.html">GtkAdjustment</A>objects. The scrolled window installs <AHREF="gtkadjustment.html">GtkAdjustment</A> objects in thechild window's slots using the set_scroll_adjustments_signal, found inGtkWidgetClass. (Conceptually, these widgets implement a "Scrollable"interface; because GTK+ 1.2 lacks multiple inheritance, this interfaceis hackily implemented as a signal in GtkWidgetClass.) </P><P> The second way to use the scrolled window is useful with widgets thatlack the set_scroll_adjustments_signal. The <AHREF="gtkviewport.html">GtkViewport</A> widget acts asa proxy, implementing scrollability for child widgets that lack theirown scrolling capabilities. </P><P> If a widget has native scrolling abilities, it can be added to the<AHREF="gtkscrolledwindow.html">GtkScrolledWindow</A> with <AHREF="gtkcontainer.html#GTK-CONTAINER-ADD">gtk_container_add</A>(). If a widget does not, youmust first add the widget to a <AHREF="gtkviewport.html">GtkViewport</A>, then add the GtkViewportto the scrolled window. The convenience function<AHREF="gtkscrolledwindow.html#GTK-SCROLLED-WINDOW-ADD-WITH-VIEWPORT">gtk_scrolled_window_add_with_viewport</A>() does exactly this, so you canignore the presence of the viewport. </P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN38720"></A><H2>Details</H2><DIVCLASS="REFSECT2"><ANAME="AEN38722"></A><H3><ANAME="GTKSCROLLEDWINDOW-STRUCT"></A>struct GtkScrolledWindow</H3><TABLEBORDER="0"BGCOLOR="#D6E8FF"WIDTH="100%"CELLPADDING="6"><TR><TD><PRECLASS="PROGRAMLISTING">struct GtkScrolledWindow;</PRE></TD></TR></TABLE><P> There are no public fields in the <AHREF="gtkscrolledwindow.html">GtkScrolledWindow</A> struct; it should only be accessed using the functions below. </P></DIV><HR><DIVCLASS="REFSECT2"><ANAME="AEN38728"></A><H3><ANAME="GTK-SCROLLED-WINDOW-NEW"></A>gtk_scrolled_window_new ()</H3><TABLEBORDER="0"BGCOLOR="#D6E8FF"WIDTH="100%"CELLPADDING="6"><TR><TD><PRECLASS="PROGRAMLISTING"><AHREF="gtkwidget.html">GtkWidget</A>* gtk_scrolled_window_new (<AHREF="gtkadjustment.html">GtkAdjustment</A> *hadjustment, <AHREF="gtkadjustment.html">GtkAdjustment</A> *vadjustment);</PRE></TD></TR></TABLE><P> Creates a new scrolled window.
