RE: FW: Making a custom widget scrollable

["Raul Davis" <raul_james_davis hotmail com>]

You need to create Gtk::Adjustment widgets and set them on a 
Gtk::ScrolledWindow to make the scroll bars to work.

Widgets that have native scroll support are for examples, Gtk::TreeView, 
Gtk::TextView and Gtk::Layout.

For other widgets that lack native scrolling, such as a Gtk::VBox or in your 
case, a Drawing Area, you probably want to add this widget to a 
Gtk::Viewport. Then add the viewport to your area of interest.
