Implementation Recommendations
- Where possible, use the built-in scrollbar handling by other widgets.
- If you need scrollbars around custom widgets, you might want to derive from GtkScrolledWindow rathern than directly interacting with a GtkVScrollbar
Cross-Widget Interactions
- Sends signals to attached widget.
