Description Mario Scalas CLA 2005-08-28 17:39:38 EDT 
It seems that SWT shows the GTK scrollbars with some gray padding: when  
scollbars are painted over a white background (as in the preferences dialog)  
the final effect is ugly. This has been verified with several GTK themes  
(ClearLooks 0.6.2, RH's BlueCurve and default GTK theme). In windows it seems  
there is no such side effect.  
 
With minor visibility the effect seems to be present in the Package Explorer 
view too, where it is minor in size and often shadowed by the thin colored 
contour eclipse draws around the currently focused view (shown in green in the 
attached screenshot). In the preferences dialog there is all white around and 
the gray padding is pretty obvious (shown in red). 
 
All screenshots comes from the ClearLooks attempt and while using Eclipse 3.1 
platform with GTK+ 2.6.7.

A GtkScrolledWindow puts 3 pixels of padding beside the scrollbars it creates:

http://developer.gnome.org/doc/API/2.0/gtk/GtkScrolledWindow.html#GtkScrolledWindow--scrollbar-spacing

This value is read-only and not something an application can set.  You will
notice this padding near the scrollbars of trees and tables in all GTK+
applications.

I think the layout of the preferences dialog is at fault here, they should not
have padding around this tree, or maybe use the BORDER style in some way. 
Moving to UI.

There are currently no plans to work on this however I would be happy to look over a contribution
