selectable label should auto-scroll
Submitted by Ben Liblit
Description
If a large text area is embedded within a scrollable window, drag-selecting beyond the visible area causes the text to scroll automatically. However, selectable labels do not exhibit the same behavior. Drag-select beyond what's visible and the label doesn't budge.
You can see this in action in the Nautilus2 "Credits" dialog. Start selecting the first listed author, and observe the lack of auto-scroll when you reach the bottom edge of the visible portion of the label.
This inconsistency is surprising, and makes it difficult to accurately select text in large scrolled labels. Scrolled labels should auto-scroll just like scrolled editable text widgets.
