- ApplicationWindow is JFace's abstraction of Shell.
- ApplicationWindow class represents a window in an application.
- ApplicationWindow contains support for a menu bar, a toolbar, a coolbar, and a status line.
|
If it has a parent Shell: |
|
ApplicationWindow(Shell parentShell)
|
|
If parentShell is null, the ApplicationWindow represents a top-level window.
Otherwise, it's a child of parentShell. |
