obscure : Java Glossary


When one or component is painted fully or partially on top of another we say it obscures the previous object. Some people use the astronomical term occults. Cover is another favourite. The Xlib people make a subtle distinction between obscure and occlude. Occlude refers to the stacking order, whether or not the windows are actually displayed, where obscures implies actual intersection on the screen. However, the Xlib definition contradicts itself, so it may be the other way around. I personally don’t like the term occlusion because it has the connotation of congealed hair stopping up a drain, or ill fitting dentures rather than simply eclipsing.
