The Scrolled Window resource panel is a simple dialog for setting the resources specific to Scrolled Window and objects derived thereof: Main Window, Scrolled Text and Scrolled List widgets.
The Traverse Obscured button is for setting the Traverse Obscured Callback: press the button to display the Callbacks panel.
The Message Window and Main Window Margin resources are only applicable to Main Window.
Since Scrolled Text and Scrolled List internally handle scrolling actions, most of the Scrolling resources are not available for these objects: they set these resources internally.
NOTES
If you cannot find the resource you want to set in this resource panel, try in the Core Resources Panel (selected from the Widget menu at the top of the WorkShop Visual Window).
