| Gtk::AspectFrame* | wrap (GtkAspectFrame* object, bool take_copy=false) |
| A Glib::wrap() method for this object. | |
A frame that constrains its child to a particular aspect ratio.
The Gtk::AspectFrame is useful when you want pack a widget so that it can resize but always retains the same aspect ratio. For instance, one might be drawing a small preview of a larger image. Because it derives from Gtk::Frame, it can draw a label and a frame around the child. The frame will be "shrink-wrapped" to the size of the child.
