For instance, one might be drawing a small preview of a larger image. GtkAspectFrame derives from GtkFrame, so it can draw a label and a frame around the child. The frame will be "shrink-wrapped" to the size of the child.<br> <p> <hr noshade> <h2>Function Member Descriptions:</h2> <a name="117"><font size=+1><b>Gtk::AspectFrame::AspectFrame</b></font></a> - Constructor with label.<br> <hr size="1" width="70%" align="left" noshade="noshade"><tt></tt> <a href="Gtk%3A%3AAspectFrame.html#117"><tt><font color=blue><b>AspectFrame</b></font></tt></a><tt>(<tt>const</tt> <tt><font color=navy>string</font></tt>& <tt><font color=blue>label</font></tt>, <tt><font color=purple>gfloat</font></tt> <tt><font color=blue>xalign</font></tt>, <tt><font color=purple>gfloat</font></tt> <tt><font color=blue>yalign</font></tt>, <tt><font color=purple>gfloat</font></tt> <tt><font color=blue>ratio</font></tt>=1.0, <tt><font color=purple>bool</font></tt> <tt><font color=blue>obey_child</font></tt>=false)</tt>;<br><blockquote> label: Label text. <P> xalign: Horizontal alignment of the child within the allocation of the GtkAspectFrame.
