Class CEScrollPaneLayout
java.lang.Object
javax.swing.ScrollPaneLayout
oracle.jdeveloper.ceditor.CEScrollPaneLayout
- All Implemented Interfaces:
- java.awt.LayoutManager, javax.swing.ScrollPaneConstants, java.io.Serializable
- public final class CEScrollPaneLayout
- extends javax.swing.ScrollPaneLayout
The CEScrollPaneLayout
lays out a custom view that looks like this:
G XXXXX V
G XXXXX V
G XXXXX V
G XXXXX V
HHHHHHHHH
Where G = Line Gutter, V = Vertical Scroll bar, H = Horizontal Scroll Bar, X = main view. This is so that we don't have blank corners that are unused, and also allows us to make the entire scrollpane non-opaque and leave it to the children to paint in.
